Chloroplast
The function of chloroplast is to convert light energy into
chemical energy. Chloroplast is an organelle found in some plant
cells and certain unicellular organisms. This is where
photosynthesis, the process by which plant use the sun's energy to
convert water and carbon dioxide to sugar takes place. The function
of the chloroplast for the plants is that it changes energy from the
sun into sugar for the plant to use as food. Chloroplasts are
membrane-bound plastids containing chlorophyll, thylakoids, grana,
and their own set of DNA molecules dispersed in the stroma. Each
component of a chloroplast has a unique role in photosynthesis and
photorespiration. Chloroplasts are organelles that enable plants and
certain algae to convert solar energy to chemical energy. They are
lens shaped organelles. They give color to the particular cell. For
example, plant leaves have green colored chloroplasts, and thus they
get a green color. Tomatoes have red colored chloroplasts, giving
them a red color. Chloroplasts are found in plant cells. Cell walls
allow plants to have rigid structures as varied as wood trunks and
leaves and vacuoles allow plant cells to change sides.
