5. Morphology Of Flowering Plants
This chapter focuses on the external structure, or morphology, of flowering plants, describing the parts like the root, stem, leaf, and flower, along with their various modifications. Evaluate your ability to identify and describe these plant structures by answering the Multiple-Choice Questions provided for this chapter.
6. Anatomy Of Flowering Plants
This chapter takes you inside the plant to study its internal structure, or anatomy. It details the different types of plant tissues, including the transport tissues xylem and phloem, and explains the process of secondary growth. Test your ability to differentiate between various plant tissues and structures by attempting the set of MCQs designed for this chapter.
7. Structural Organisation In Animals
This chapter explains how animal cells are organized into the four primary animal tissues: Epithelial, Connective, Muscular, and Nervous. It illustrates this organization through a detailed study of the anatomy of the earthworm, cockroach, and frog. Test your knowledge of histology with the set of MCQs available for this chapter.
8. Cell - The Unit Of Life
This chapter reinforces the cell as the fundamental unit of life. It details the structure and function of various cell organelles, such as the mitochondria and the nucleus, and distinguishes between prokaryotic and eukaryotic cells. Assess your understanding of cell biology by solving the MCQs provided in this section.
9. Biomolecules
This chapter explores the chemistry of life, detailing the structure and function of the four major classes of biomolecules: Carbohydrates, Proteins, Lipids, and Nucleic Acids (DNA and RNA). It also introduces enzymes as biological catalysts. To deepen your understanding of these vital molecules, this section provides a range of Multiple-Choice Questions.
10. Cell Cycle And Cell Division
This chapter describes the life of a cell, the cell cycle, and the two crucial types of cell division: Mitosis (for growth and repair) and Meiosis (for sexual reproduction). It details the distinct stages of both processes and the significance of crossing over. To practice these complex cellular events, attempt the set of MCQs available through the link for this chapter.
11. Transport In Plants
This chapter explains how plants transport water, minerals, and food through their vascular tissues. The upward movement of water through the xylem is explained by the transpiration pull theory, and the translocation of sugars through the phloem is explained by the pressure-flow hypothesis. Reinforce your understanding of these vital transport mechanisms by answering the MCQs linked here.
12. Mineral Nutrition
This chapter focuses on the essential inorganic nutrients plants need, classifying them into macronutrients and micronutrients. A significant portion is dedicated to the crucial process of nitrogen metabolism, including biological nitrogen fixation. Have fun testing your knowledge of plant nutrition with the interactive MCQs provided for this chapter.
13. Photosynthesis In Higher Plants
This chapter provides a detailed biochemical understanding of photosynthesis, breaking it down into the light-dependent reactions and the light-independent reactions (the Calvin cycle). It also discusses alternative pathways like the C4 pathway. Challenge yourself with MCQs on this vital life-sustaining process by clicking the link for this chapter.
14. Respiration In Plants
This chapter details how plants release energy from food through cellular respiration. It focuses on the stages of aerobic respiration: Glycolysis, the Krebs cycle, and the electron transport system. Evaluate your understanding of these complex metabolic pathways by answering the Multiple-Choice Questions provided for this chapter.
15. Plant - Growth And Development
This chapter explores the processes that govern a plant's life, detailing the roles of the five major types of plant growth regulators (phytohormones). It also explains how plants respond to environmental cues through phenomena like photoperiodism and vernalisation. Test your grasp of plant physiology by solving the MCQs provided for this chapter.
16. Digestion And Absorption
This chapter explains the process of nutrition in humans, detailing the structure and function of the human digestive system. It describes how complex food molecules are broken down during digestion and then taken into the body during absorption. Evaluate your understanding of human physiology by attempting the MCQs provided in this section.
17. Breathing And Exchange Of Gases
This chapter details the mechanism of gaseous exchange in humans. It describes the anatomy of the human respiratory system and explains the mechanics of breathing and the exchange of gases in the lungs and tissues, which is driven by pressure gradients. Assess your knowledge of this vital process by solving the MCQs available for this chapter.
18. Body Fluids And Circulation
This chapter describes the internal transport system of the human body, detailing the composition of blood and the structure and function of the heart. It explains the cardiac cycle and the concept of double circulation. It also covers the ABO and Rh blood groups. To test your knowledge of the circulatory system, attempt the Multiple-Choice Questions provided in this section.
19. Excretory Products And Their Elimination
This chapter explains how the body removes metabolic wastes through the process of excretion. It focuses on the human excretory system and the three main steps of urine formation in the nephron: glomerular filtration, selective reabsorption, and tubular secretion. To practice these complex physiological concepts, attempt the set of MCQs available for this chapter.
