Oh! Plastids! What a
coincidence. Those are
my favorite part of the
cell! Lets get started.
Chloroplast
Lets begin with talking about the
three types of plastids. This includes
the Chloroplast, Chromoplast, and
the Leucoplast. They are all found in
the Plant Cell.
Chromoplast
Leucoplast
Chloroplasts
You can find Chloroplasts in
green plant cells. They are
responsible for Photosynthesis
and contain chlorophyll which is
where it takes place. Although
the chloroplast has no specific
location, it floats around the
cell, and is part of the
cytoplasm. It is lens-shaped and
about 5 microns long, although
size can vary.
Chromoplasts
Chromoplasts are found in flower, fruit, and some root
cells. They give them the distinct red, orange, or yellow
color because of caroteniod. Like the Chloroplasts, they are
lens shaped. Chromoplasts are responsible for pigment
synthesis and storage. They are also found in the
cytoplasm, floating around the cell.
Leucoplasts
Found in roots, seeds, and underground
stems. They are colorless and not exposed to
light. Their job is to store starch and protein.
Like the other plastids, They are lens shaped
and float around in the cytoplasm.
Have you ever wondered why
blueberries are blue? The
chromoplasts are not the reason.
The true blue color comes from
the high content of anthocyanin!
