|What is a chloroplast in a cell?
|Question Date: 2014-09-10|
A chloroplast is an organelle (like an organ, but
for a cell) that collects light and turns it into
energy that the cell can use. It is the place
where carbon dioxide and water are broken down and
put back together again as oxygen and sugar, and
sugar being the energy source for (nearly) all
life, plant and animal alike.
A chloroplast is an organelle found in plant
cells. It is responsible for harvesting light
energy (photons) from the sun and converting it
into chemical energy (sugar) so that the plant can
use it for grow, among other things.
A cool fact about chloroplasts is that
scientists think that a very long time ago,
chloroplasts were individual organisms and at one
point in evolutionary history became incorporated
into other cells, effectively converting them into
organelles that generate energy for the plant
It is an organelle. This means it's like an
organ is to the body, but much smaller because it
is inside a cell. Like the stomach has the
chemicals and functions to break down food, the
chloroplasts have the right structure to perform
the chemical reactions that let them take energy
in from sunlight. Basically, they build sugars
using sunlight and carbon dioxide from the air and
water from the soil.
Chloroplast is the structure in plant cells
that performed photosynthesis, where sunlight is
transformed into energy. The chloroplast makes
and stores the cell's energy. The chloroplast is
usually a green color because of the chlorophyl
that is inside it.
