Please select the letter corresponding to the cell
part to know more about it.
Cell Membrane
It is a thin layer of protein and fat that surrounds the cell.
The cell membrane is semipermeable, allowing some
substances to pass into the cell and blocking others.
Back to Diagram
Lysosome
It is a round organelles surrounded
by a membrane and containing
digestive enzymes. This is where
the digestion of cell nutrients
takes place. It is also called cell
vesicles.

Nucleus
It is a membrane-bound organelle and
is surrounded by a double membrane.
It communicates with the surrounding
cytosol via numerous nuclear pores.
The nucleus houses the DNA which
stores genetic information for a cell.
The DNA contains instructions for the
production of the cell's proteins and
for reproduction.

Nucleolus
It is an organelle within the
nucleus – it is where ribosomal
RNA is produced. Some cells
have more than one nucleolus.
Back to Diagram
Nuclear Membrane / Pore
It is the membrane that surrounds the nucleus.
Back to Diagram
Vacuole
It is a fluid-filled, membrane surrounded cavities inside a cell.
The vacuole fills with food being
digested and waste material that
is on its way out of the cell.
Back to Diagram
Mitochondrion
It is spherical to rod-shaped organelles
with a double membrane. The inner
membrane is infolded many times,
forming a series of projections
(called cristae). The mitochondrion
converts the energy stored in glucose
into ATP (adenosine triphosphate)
for the cell.

Golgi Body
A flattened, layered, sac-like
organelle that looks like a
stack of pancakes and is
located near the nucleus. It
produces the membranes
that surround the lysosomes.
The Golgi body packages
proteins and carbohydrates
into membrane-bound
vesicles for "export" from the
cell.
Back to Diagram
Ribosomes
Small organelles composed of
RNA-rich cytoplasmic
granules that are sites of
protein synthesis.
Back to Diagram
Smooth Endoplasmic Reticulum (ER)
A vast system of interconnected, membranous, infolded and convoluted tubes
that are located in the cell's cytoplasm (the ER is continuous with the outer
nuclear membrane). Smooth ER transports materials through the cell. It
contains enzymes and produces and digests lipids (fats) and membrane
proteins.
Back to Diagram
Rough ER
A vast system of interconnected, membranous, infolded and
convoluted sacks that are located in the cell's cytoplasm
(the ER is continuous with the outer nuclear membrane). Rough ER is
covered with ribosomes that give it a rough appearance.

Cytoplasm
The jellylike material outside the cell
nucleus in which the organelles are
located.
Back to Diagram
Centrosome
A small body located near the nucleus - it has
a dense center and radiating tubules. The
centrosomes is where microtubules are made.
During cell division (mitosis), the centrosome
divides and the two parts move to opposite
sides of the dividing cell. The centriole is the
dense center of the centrosome.
