Plant Cell & cycle

Powerhouse of the plant cell The chloroplast is the site
where light energy is used to produce the organic molecules
required by the plant cell. In this image, the flattened and stacked
membranes of the grana can be seen inside the chloroplast.
Chlorophyll and other pigments embedded in the chloroplast
membranes capture the sun’s energy, the first step in the process
essential to life—photosynthesis.
