Life Science LAQs: Get a comprehensive guide to WBBSE Class 10 Life Science long answer questions with important topics and exam tips for better preparation.
WBBSE Class 10 Life Science long answer questions cover a variety of topics, testing students’ understanding of key concepts in biology. To prepare effectively for these questions, students should focus on key areas of the syllabus, such as the structure and function of cells, human physiology, plant physiology, genetics, and environmental science.
1. Cell Structure and Function: One common long answer question could ask about the structure and function of different organelles in plant and animal cells. Here, students are expected to explain in detail the roles of the nucleus, mitochondria, ribosomes, and other organelles, and how they contribute to the overall function of the cell.
2. Human Physiology: Questions related to the digestive, respiratory, circulatory, and excretory systems of humans often appear. Students might be asked to describe the structure of the heart, the process of digestion in humans, or the pathway of air during respiration. Understanding these systems, their functions, and the interconnections between them is essential for answering these questions.
3. Plant Physiology: In this section, students could be asked to explain processes like photosynthesis, transpiration, and respiration in plants. They should be able to describe the stages of photosynthesis, including the role of chlorophyll and the importance of sunlight, water, and carbon dioxide.
