First year science students 5 chapter imp questions for biology subject 🙀🌟

🧪🧫🔭 padho smart 🤓 For first-year science students studying biology, focusing on the most important and high-yield topics will help in preparing effectively for exams. Here are 5 key chapters along with important questions that are typically emphasized: 1. Cell Biology 🧫 Important Questions: __Describe the structure and function of the cell membrane. __Explain the difference between prokaryotic and eukaryotic cells. __Discuss the process of mitosis and its stages. __Define the structure of a plant and animal cell with labeled diagrams. __What is the role of ribosomes and the endoplasmic reticulum in protein synthesis? 2. Human Physiology Important Questions: __Explain the structure and function of the human digestive system. __Describe the human circulatory system and its components. __How does the respiratory system facilitate gas exchange? __Discuss the role of the kidney in excretion. __What are the major hormones of the human endocrine system and their functions? 3. Plant Physiology Important Questions: __Describe the process of photosynthesis, including the light and dark reactions. __What is transpiration, and how does it affect plant growth? __Explain the process of plant respiration. __Discuss the role of hormones in plant growth and development. __Describe the structure of the vascular tissue in plants and its functions. 4. Genetics and Evolution Important Questions: __Explain Mendel's laws of inheritance with suitable examples. __Discuss the structure and function of DNA. __What is genetic recombination and how does it contribute to genetic variation? __Discuss the process of evolution by natural selection. __Explain the concept of genetic mutations and their role in evolution. 5. Ecology Important Questions: __Define an ecosystem and explain its components. __Describe the energy flow in an ecosystem (food chains and food webs). __What is the significance of biodiversity? __Explain the biogeochemical cycles (e.g., nitrogen, carbon, water). __Discuss the impact of human activities on ecosystems. General Tips: {Diagrams: Be prepared to draw and label diagrams such as cell structure, digestive system, circulatory system, photosynthesis process,} etc. Key Terms: Understand the definitions of key biological terms like osmosis, diffusion, enzymes, and so on. Practical Applications: Some questions may ask you to apply theoretical knowledge to practical scenarios, such as how diseases or environmental changes affect human physiology or ecosystems.
