List some organelles found in an animal cell but NOT found in a plant cell.

The cellular structure of animals and plants is very
similar though there are a few organelles that are present in animal cells but not
present in plant cells.


Some of these
are:


Cilia: these are hair like structures found on the
outer surface of cells. Cilia have two purposes. The motile cilia help in locomotion
while sensory cilia detect substances on the cellular
membrane.


Flagella: these are similar to cilia but are
larger in size. They play the same roles of locomotion, moving substances over the cell
membrane and in sensing and in signal
transduction.


Centrioles: These are organelles without
membranes that are located outside the nucleus in animal cells. Each of these is a
cylinder made of nine sets of microtubule triplets.
