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.

VacuoleCentral 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. Both4. Both**** color this organelle

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.

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

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. Both4. 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.

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. Both4. Euk.

MitochondriaMitochondrion (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. Both4. 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 ERsometimes free in cytoplasm

3. Both4. Both

Nucleolus

1. Job: Makes ribosomes

2. Location in cell:Dark spot inside nucleus

3. Both

4. Euk.
