2. THREE BASIC PARTS OF
THE CELL
1. Cell Membrane
2. Nucleus
3.Cytoplasm
3. Cell Membrane
-Every cell is surrounded by a
cell membrane.
-It is sometimes called a plasma
membrane.
-The cell membrane separates
the cell from its external
environment and from the
neighboring cells.
4. Nucleus
-The nucleus is the most
important organelle (Little Body)
within the cell. It has two vital
functions; to control the
activities of the cell and to
facilitate cell division.
-This spherical organelle is
usually located in or near the
center of the cell.
5. Cytoplasm
- Cytoplasm is a sticky, semi
fluid material found between
the nucleus and the cell
membrane. Chemical analysis
of the cytoplasm shows that it
consists of proteins, lipids,
carbohydrates, minerals, salts,
and water.
9. Mitochondrion
"powerhouse of the
cell" breaks down
sugar molecules to
release energy, site of
cellular respiration,
double membrane,
self-replicating,
contains own DNA,
cristae
12. Endoplasmic
Reticulum
(ER)
*Transportation network for
the cell, moves materials
around in the cell.
*Rough Endoplasmic
Reticulum (RER)-
endoplasmic reticulum that
has ribosomes attached.
*Smooth Endoplasmic
Reticulum (SER)- does not
have ribosome's attached
13. Lysosome
"Stomach of the cell“
or “Suicide sacs”.
Helps the cell digest
food, waste and worn
out cell parts
14. Chloroplast
A special plastid that
contains chlorophyll
a pigment that
captures the sun's
energy to produce
glucose in a process
called
photosynthesis
15. Cell Wall
Rigid outer layer
made of cellulose
that supports and
protects the cell
(plant, fungi, and
bacterial cells)
18. Centriole
Organizes special
parts of the
cytoskeleton called
microtubules for cell
division, migrates to
opposite ends
(poles) of the cell to
assist with cell
division
