4. Cell Organelles
1
You explored the cell during the
webquest
Now we will discuss a few of the more
common cell organelles
2
Vocabulary:
organelles
Parts of a cell that do different jobs in
the cell
3
Cell Membrane
1. Can find in both plant
and animal cells
2. Gives support and protection to
the cell
3. Controls entry in and out of the
cell
4
Vocabulary:
Cell membrane
A part of the cell that controls entry in
and out of the cell
5
Nucleus
1. Large and oval in appearance
2. Controls cell activity
3. The brain (or boss)
6
Vocabulary:
nucleus
A part of the cell that controls the
activity of a cell (brain)
7
Cytoplasm
1. Clear, thick jelly like substance
that holds the organelles
2. Supports and protects the
organelles
8
Vocabulary:
cytoplasm
A part of the cell that supports and
protects organelles
9
Endoplasmic Reticulum
1. Network of tubes or
membrane
2. Carries materials through the cell
3. The “conveyor belt” of the cell
10
Vocabulary:
Endoplasmic reticulum
Part of the cell that carries materials
throughout the cell
11
Ribosome
1. Small round bodies attached to the
endoplasmic reticulum or floating
in the cytoplasm
2. Produces proteins
3. Looks like little ticks
12
Vocabulary:
ribosomes
Part of the cell that produces proteins
for the cell
13
Mitochondrion
1. Bean shaped with inner
membranes
2. Breaks down sugar molecules into
energy
3. The “power plant” of the cell
14
Vocabulary:
mitochondria
Part of the cell that breaks down sugar
molecules to make energy
15
Vacuole
1. Fluid filled sacs
2. Stores food, water, and wastes
3. The “storage containers” of the
cell
16
Vocabulary:
vacuole
Part of the cell that stores food, water
and wastes in a cell
17
Lysosome
1. Small and round with a membrane
2. Breaks down food molecules
3. Digests old cell parts
18
Vocabulary:
lysosome
Part of the cell that breaks down food
molecules and digests old cell parts
19
Chloroplast
1. In plant cells only
2. Green and oval with chloroplasts
3. Uses energy from the sun to make
food
20
Vocabulary:
chloroplast
Part of the plant cell that uses energy
from sun to make food
21
Cell Wall
1. In plant cells only
2. Rigid outer layer that
gives support and
protection to the cell
3. Allows H2O, CO2, and O2 to pass
in and out of the cell
22
Vocabulary:
Cell wall
Part of the plant cell that provides
support and protection
