## Step 1The question is asking us to identify the true statement about photosynthesis. Photosynthesis is a process that converts light energy, usually from the sun, into chemical energy that can be later released to fuel the organisms' activities. This process is carried out by plants, algae, and some bacteria.## Step 2The first option states that photosynthesis converts carbohydrates and oxygen into carbon dioxide and water. This is incorrect. In photosynthesis, carbon dioxide and water are converted into carbohydrates (glucose) and oxygen, not the other way around.## Step 3The second option suggests that photosynthesis occurs when light energy is not available. This is also incorrect. Photosynthesis requires light energy to convert carbon dioxide and water into glucose and oxygen.## Step 4The third option proposes that photosynthesis converts chemical energy into light energy. This is not true. Photosynthesis does the opposite: it converts light energy into chemical energy.## Step 5The fourth option states that photosynthesis occurs only in cells that contain chlorophyll. This is true. Chlorophyll is a pigment that absorbs light energy and is essential for photosynthesis. It is found in the chloroplasts of plant cells.
