ANIMAL CELL ORGANELLES

1.       Nucleolus

Ø  Inside the nucleus

Ø  The place where ribosomes are assembled

2.       Nucleus

Ø  Contains chromatin or DNA (the protein building instructions)

Ø  Controls the cell

3.       Nuclear Envelop

Ø  Double membrane between nucleus and cytoplasm

Ø  Dotted with thousands of nuclear pores which allows material to move into and out of the nucleus

4.       Ribosome

Ø  Small complexes of RNA and Protein

Ø  Known as the “Factory”

Ø  Sites of protein synthesis (where amino acids connect to each other making a polypeptide chain)

                 

5.       Rough ER (Endoplasmic Reticulum)

Ø  Internal membranes studded with ribosomes which then carry out protein synthesis and exported

Ø  Produces membrane

Ø  Continuous with the nucleus

6.       Smooth ER (Endoplasmic Reticulum)

Ø  Contains enzymes.

Ø  The enzymes produce the synthesis of membrane lipids and detoxify drugs.

7.       Golgi Complex

Ø  Collects packages and sends it to the right place

Ø  Adds carbs

8.       Cell Membrane

Ø  Consists of lipid bilayer with embedded proteins

Ø  Regulates the entrance and exit of substances trying to maintain internal balance

Ø  Protects inner cell from damage

9.       Centrioles

Ø  Help cell when dividing

Ø  They are put to work in both the process of mitosis and meiosis

10.   Mitochondrion

Ø  Generates energy  (ATP) for the cell
