Chapter 1: Living World
This chapter is entitled "What does it mean to live?" Expands on basic concepts such as Diversity in the living world, classification categories, taxonomic aids, and more. The living world is rich with diversity. Millions of plant and animal species have been identified and described to date, but many remain. Various plant and animal taxonomic studies are useful in agriculture, forestry, industry, and in general to find out our resources and their diversity. Taxonomists have developed a variety of taxonomic aids to facilitate the identification, naming and classification of organisms.
Chapter 2: Biological Classification
In this chapter, we study the properties of Monera, Protista and fungi of the classification of the Whittaker system. The Plante and Animalia states, commonly called plant and animal states, are dealt with separately in Chapters 3 and 4, respectively. You will also study Kingdom Monera, Kingdom Protista, Kingdom Fungi, Kingdom Shen, Kingdom Animalia, Virus. Viroids and lichens.
Chapter 3: Plant Kingdom
In the previous chapter, we looked at a broad classification of organisms under the system proposed by Whitaker (1969), in which he referred to the five kingdom classification. Monera, Protista, Fungi, Anemia and Plantae. In this chapter, we will go into detail with further classification in the Kingdom Plante or ‘Plant Kingdom’. Along the way, you will learn concepts such as algae, bryophytes, peridophytes, gymnosperms, angiosperms, plant life cycles and the substitution of genera.
Chapter 4: Animal Kingdom
When we look around, we notice different animals with different structures and forms. With more than a million species of animals described so far, the need for classification is above all important. Taxonomy also helps to provide a systematic condition for newly described species. It teaches the classification of Aadhaar, classification of animals and more.
Chapter 5: Morphology of Flowering Plants
In Chapters 2 and 3, we talked about plant classification based on morphological and other characteristics. For a successful attempt to understand taxonomy and any superior plant (or any organism), we need to know the standard technical terms and standard definitions. We also need to be aware of the possible variations in the different parts that plants perceive as adaptations to their environment, adapting to different habitats for conservation, climbing and storage. It describes aspects such as root, stem, leaf, inflorescence, flowers, fruits, seeds, semi-technical description of a particular flowering plant, description of some important families, and more.
Chapter 6: Anatomy of Flowering Plants
This chapter introduces the internal structure and functional organization of most plants. Anatomy is the study of the internal structure of plants. Plants contain plants as their primary units, cells form tissue, and tissues are organized in different parts of the plant. Within angiosperms, monocots and dicots are anatomically distinct. Infrastructures also show adaptation to different environments. This includes Tissues, The Tissue System, Anatomy of Dicotyledonous and Monocotyledonous Plants, Secondary Growth and so on.
Chapter 7: Structural Organisation in Animals
In previous chapters, we have seen a large number of single-cell and multiple cellular organisms of the animal kingdom. In unicellular organisms, all functions such as digestion, respiration, and reproduction are performed by a single cell. In a complex body of multi-cellular animals, the same basic function is carried out systematically by different groups of cells. There are only four basic types of tissues in all complex animals. These tissues are held in specific locations to form organs such as the stomach, the kidneys, the heart and the kidneys.
Chapter 8: Cell The Unit of Life
When you look around, you see living and lifeless things. You may be asking yourself - "What keeps a creature alive?" Or, "What does the inanimate object lack in living things?" The answer is the existence of a cell in all living things - the primary unit of life. All living things are made of cells. Some are made up of a single cell and are called unicellular organisms. On the contrary, others, like us, are made up of many cells and are called multiple cellular organisms.
Chapter 9: Biomolecules
There are many kinds of organisms in our biosphere. A few more topics covered in this chapter include how to analyze chemical composition. Primary and secondary metabolites, biomacromolecules, proteins, polysaccharides, nucleic acids, protein structure, nature of monomers linking in polymer, dynamic state of body movement - diabetes of metabolism, metabolism of metabolism, living condition, enzyme.
Chapter 10: Cell Cycle and Cell Division
Growth and reproductive cells are, in fact, the characteristics of all living things. All cells divide and reproduce, each time the two daughter cells divide in each parent cell. These newly formed daughter cells can grow and divide on their own, leading to new cell populations that are formed by the growth and division of a single parent cell and its offspring. In other words, such cycles of growth and division create a single cell with millions of cells. Other subtypes mentioned in the chapter are the cell cycle, M phase, the importance of mitosis, meiosis, meiosis.
Chapter 11: Transport in Plants
Topics in this chapter include transport routes, plant-water relationships, water transport, transpiration, mineral nutrients and nutrients, phloem, transport: flow from source to sink. Plants derive a variety of inorganic elements (ions) and salts from their surroundings, especially water and soil. In high plants, there is a vascular system consisting of xylem and phloem, which is responsible for translation. Phloem is responsible for transporting food (mainly) from the food source to the sink. The translation pressure in the phloem is explained by the flow - flow hypothesis.
Chapter 12: Mineral Nutrition
This chapter focuses primarily on the nutrition of inorganic plants, in which we study the criteria for identifying and establishing the essential elements for plant growth and development. We also study the role of the essential elements, their major drawbacks, and the way they perceive these important elements. This chapter provides a brief introduction to the importance and mechanism of biological nitrogen fixation.
Chapter 13: Photosynthesis in Higher Plants
All animals, including humans, depend on plants for their food. Green plants produce or make the food they need through photosynthesis, so it is called autotrophs. Green plants perform yn photosynthesis, a physicochemical process that uses light energy to drive the synthesis of organic compounds. Photosynthesis is important for two reasons: it is the basis for all known food chains on Earth. It is also responsible for the release of oxygen into the atmosphere by green plants. This chapter focuses on the structure of photosynthesis and the various reactions that convert light energy into chemical energy.
Chapter 14: Respiration in Plants
This chapter deals with the trapping of this energy for cellular respiration or the breakdown of foods within the cell to release energy and the synthesis of ATP. This chapter also expands on topics such as "suck the plants". Glycolysis, fermentation, aerobic respiration, respiratory balance sheet, amphibian route, respiratory quota.
Chapter 15: Plant Growth and Development
We have already studied the organization of flowering plant in chapter 5. In this chapter, we explore some of the factors that govern and control these development processes. These factors are both internal (external) and external (external) to the plant. Growth Differentiation, Dedifferentiation and Redifferentiation, Development, Plant Growth Regulators, Photoperiodism, Vernalization and many other sub-developments.
Chapter 16: Digestion and Absorption
Food is one of the basic needs of all living things. The main components of our diet are carbohydrates, proteins and fats. Even small amounts of vitamins and minerals are required. Diet provides energy and biological materials for the growth and repair of tissues. The water we consume plays an important role in metabolic processes and also prevents dehydration of the body. Biomacromolecules in food cannot be used by our bodies in their basic form. They need to be broken down and turned into normal ingredients in the digestive tract. This process of converting complex foods into simple absorptive forms is called digestion and is carried out by our digestive system in mechanical and biochemical ways.
Chapter 17: Breathing and Exchange of Gases
As you may have read earlier, oxygen is used indirectly by organisms to break down common molecules, such as glucose, amino acids, fatty acids, and energy to perform various functions. Harmful carbon dioxide is also released during metabolic reactions. Therefore, it is clear that the cells must constantly provide oxygen and excrete the carbon dioxide that the cells produce. This process of exchanging oxygen from the atmosphere with carbon dioxide produced by the cells is called breathing. It is also called respiration.
Chapter 18: Body Fluids and Circulation
We have learned that nutrients, oxygen, and other essential substances must be provided to all living cells. Also, the waste or harmful substances produced for the healthy functioning of the tissues must be constantly removed. Blood is the most commonly used body fluid in most organisms, including humans. Another body fluid, lymph, also helps in the transport of certain substances. In this chapter, we explore the structure and properties of the blood and lymph (tissue fluid), and the mechanism of blood circulation.
Chapter 19: Excretory Products and their Elimination
This chapter describes aspects of the human excretory system, the formation of the urine, the function of the vessels, the filtration system, the control of renal function, the role of other organs in diffusion, excretion, and defects of the excretory system.
Chapter 20: Locomotion and Movement
Movement is one of the most important characteristics of living things. Animals and plants make a variety of moves. Such voluntary movements are called motions. Walking, running, climbing, jumping and swimming are all locomotive moves. Locomotive structures do not need to be different from those that affect other types of movement. The way animals move is adapted to their habitat and condition. Locomotion is necessary for many reasons including survival from food, shelter, companions, suitable breeding grounds, favorable climatic conditions or predators.
Chapter 21: Neural Control and Coordination
Coordination is the process by which two or more organs interconnect and complement each other. In our body, the nervous system and the endocrine system jointly coordinate and integrate all the activities of the organs so that they function in a balanced manner. In this chapter, we will learn about the physiology of the human nervous system, the mechanisms of neurodegeneration, the mechanisms of nerve coordination, impulse circulation and reflex action across synapses.
Chapter 22: Chemical Coordination and integration
We already know that the nervous system coordinates rapidly between organs. Nervous coordination is fast, but short-lived. Since nerve fibers cannot infect all cells of the body, and cellular functions need to be constantly controlled; Special coordination and integration must be provided. This work is done by hormones. The nervous system and the endocrine system jointly coordinate and regulate the physiological functions of the body.
