Cell Organelles
2010
Centrioles
1. Job: separates chromosomes during cell division
2. Location in cell:
There are only two centrioles found on opposite
sides of the cell, near the cell membrane
3. Animals only*** there are conflicting reports on this
4. Euk.
**** color this organelle
Vacuole
Central vacuole (in plants)
1. Job:
Storage of water, sugar, salt, etc. & support for
plants
2. Location in cell:
In plants there is one large vacuole in center of cell,
that provides support for the plant.
In animals there are many small vacuoles throughout
the cytoplasm.
• Both plant and animal
• Euk.

Cell Membrane
1. Job: hold in contents of cell, and control what
substances enter and leave the cell.
2. Location in cell:
Animals: outermost part of the cell.
Plants: just inside the cell wall.
3. Both
4. Both

Cell Wall
1. Job: Provides structural support for plants
2. Location in cell:
Outermost part of the plant cell.
3. Plants
4. Euk.

Chloroplasts
1. Job: makes food (sugars) from sunlight
2. Location in cell:
In cytoplasm, near the cell membrane.
** not found in plant roots. Why?
3. Plants
4. Euk.
**** color this organelle
Chromatin
**long stands of chromatin form chromosomes
1. Job:
Stores gentic information (it is long piece of
DNA)
2. Location in cell:
Inside nucleus
3. Both
4. Both
**** color this organelle
Cytoplasm
1. Job:
provides support and transportation to various
substances and organelles in the cell
2. Location in cell:
everywhere inside the cell, except in the nucleus.
** 65% water
3. Both
4. Both

ER
1. Job:
helps in making and packaging proteins,
steroids, glycogen, etc.
2. Location in cell:
Near nucleus
*** rough ER has ribosomes on the outside, smooth
ER does not.
3. Both
4. Euk.
**** color this organelle
Golgi Body
1. Job:
Packages, stores, and transports proteins and
other materials made in ER
2. Location in cell:
Between ER and cell membrane
3. Both
4. Euk.

Lysosomes
1. Job: contain enzymes to break down bacteria and
harmful substances and recycle old cell parts.
2. Location in cell:
floating in cytoplasm
*** white blood cells, which fight disease have very
high # of lysosomes.
3. Both
4. Euk.

Mitochondria
Mitochondrion (singular)
1. Job: converts food into energy for the cell.
AKA: “powerhouse of the cell”
2. Location in cell:
in cytoplasm
*** muscles cells, which use a lot of energy, contain
high # of mit.
3. Both
4. Euk.

Nucleus
1. Job: Stores DNA, and directs all of cells
activities. AKA: “the brain”
2. Location in cell:
Animals: center of the cell
Plants: as close to center as vacuole will allow.
3. Both
4. Euk

Nuclear Membrane
1. Job: protects nucleus, controls what goes in or out
2. Location in cell:
Surrounding the nucleus
3. Both
4. Euk.

Ribosomes
1. Job: Produce/ make proteins
2. Location in cell:
sometimes on ER
sometimes free in cytoplasm
3. Both
4. Both

Nucleolus
1. Job: Makes ribosomes
2. Location in cell:
Dark spot inside nucleus
3. Both
4. Euk.
