4. If a student is conducting a photosynthesis experiment, which part of the plant should she use to obtain a sample of chloroplasts? A stems B roots C bark D leaves

## Step 1<br />The question is asking about the part of the plant where chloroplasts are located. Chloroplasts are the organelles in plant cells where photosynthesis occurs. <br /><br />## Step 2<br />Photosynthesis is the process by which plants convert light energy, usually from the sun, into chemical energy in the form of glucose. This process is essential for the survival of plants and also for all life on Earth.<br /><br />## Step 3<br />The options given are stems, roots, bark, and leaves. Among these, the leaves are the primary site of photosynthesis in most plants. This is because the leaves contain a high concentration of chloroplasts, which are the organelles where photosynthesis takes place.
