The correct Answer is:
To determine which statements are correct, let's analyze each statement one by one: ### Step 1: Analyze Statement I **Statement I:** Mitochondria are the sites of anaerobic respiration. - **Analysis:** This statement is incorrect. Mitochondria are primarily known as the sites of aerobic respiration, where oxygen is used to produce ATP (adenosine triphosphate). Anaerobic respiration occurs in the cytoplasm and does not require oxygen. ### Step 2: Analyze Statement II **Statement II:** Mitochondria are typically sausage-shaped. - **Analysis:** This statement is correct. Mitochondria are often described as having a sausage or rod-like shape, which is typical for these organelles. ### Step 3: Analyze Statement III **Statement III:** Chlamydomonas cell is having one chloroplast and one mitochondrion in it. - **Analysis:** This statement is incorrect. Chlamydomonas, a unicellular green algae, typically has one chloroplast, but it usually contains more than one mitochondrion. Therefore, this statement is misleading. ### Step 4: Analyze Statement IV **Statement IV:** Stroma part of chloroplast contains enzymes required for the synthesis of proteins and carbohydrates. - **Analysis:** This statement is correct. The stroma of chloroplasts contains enzymes that are involved in the Calvin cycle, which is essential for the synthesis of carbohydrates and also plays a role in protein synthesis. ### Conclusion After analyzing all statements: - **Correct Statements:** Statement II and Statement IV are correct. - **Incorrect Statements:** Statement I and Statement III are incorrect. ### Final Answer The correct answer is that Statements II and IV are true. ---
