<span>Sunlight emits light energy which is absorbed by the thylacoids in
the chloroplasts of a plant. Chloroplasts are organelles in a plant
cell whose funtion is photosynthesis (the use of light to make
energy). Thylacoids are a part of the chloroplast which absorbs
light. The thylaciods convert the light into energy molecules NADPH
and ATD. The Calvin cycle then takes place in the stroma
(gellatinous matrix of the chloroplast). The Calvin cycle is the
use of ATP and NADPH plus carbondioxide to produce starch. Starch
is the polysaccharide sugar formed from glucose synthesized in a
linear chain. The starch is the storage of the glucose which is
used as an energy source for the plant cells. </span>
