The Nucleus

Nucleus-structure

-2 membranes with fluid between them

-surrounded by nuclear envelope

-Nuclear pore

-has chromatin

-nucleolus inside nucleus

Function:

-has the cells genetic material

-Chromatin consists of DNA and proteins ( has instructions for making proteins)

-Nucleolus makes RNA and ribosomes 

Endoplasmic Reticulum

Endoplasmic Reticulum 

Structure

-Consists of flattened bound membrane sacs called cisteranae.

- ROUGH ER HAS RIBOSOMES, 

-SMOOTH ER DOES NOT

Function:

Rough ER transports proteins

Smooth ER makes lipids

Nucleus

Function:-has the cells genetic material

-Chromatin consists of DNA and proteins ( has instructions for making proteins) and

 Nucleolus makes RNA and ribosomes 

Golgi Apparatus 

Structure

-A stack of membrane bound flattened sacs

Function: Recieves proteins from rough endoplasmic reticulum and modifies them

-Adds sugar molecules

-Packages the modified proteins into vesicles.

Mitochrondia

Structure : Spherical= 2 membranes seperated by a fluid filled space

Function: Produces ATP= provides energy for cell

Chloroplasts 

Structure: Found in plant cells

- 2 membranes seperated by a fluid filled space

Function : site of photosynthesis

Lysosomes 

Structure 

-Spherical sacs surrounded by a single membrane

Function: contains powerful digestive enzymes that break down matter
