I. a cell structure found in plants that captures energy from sunlight and converts it into chemical energy

Answer 1

The cell structure you are referring to is called a chloroplast. Chloroplasts are organelles found in plant cells (and some other organisms) that contain chlorophyll, the pigment responsible for capturing sunlight. This process is known as photosynthesis, where light energy is converted into chemical energy in the form of glucose, which the plant can then use for growth and energy.
