Golgi apparatus is one of
the important organelles
found in eukaryotic cells.
Directing the
carbohydrates and
proteins, needed by the
body, to their proper
destination is the main
function of this cell
organelle.
In the process of
directing protein and
carbohydrate molecules
to their appropriate
destinations, they are
tagged with details
about the destination
and structural
modifications.

Cytoskeleton


The cytoskeleton (also CSK) is a
cellular scaffolding or
skeleton contained within a
cell's cytoplasm.
The cytoskeleton is present in all
cells; it was once thought to be
unique to eukaryotes, but recent
research has identified
the prokaryotic cytoskeleton.
It forms structures such
asflagella, cilia and lamellipodia a
nd plays important roles in both
intracellular transport (the
movement of vesicles and
organelles, for example)
and cellular division.

Lysosomes are the cell's
waste disposal system
and can digest some
compounds
Transport undisgested
material to cell membrane
for removal

Centrioles



A centriole is a cylinder shaped cell
structure found in
most eukaryotic cells, though it is
absent in higher plants and most fungi.
An associated pair of centrioles,
arranged perpendicularly and
surrounded by an amorphous mass of
dense material, called the
pericentriolar material, or PCM, makes
up a compound structure called a
centrosome.
Centrioles are involved in the
organization of the mitotic spindle and
in the completion of cytokinesis
