Mitocondria

A

An organelle with a highly folded inner membrane surrounded by a second outer membrane. Mitchocondria is a site of aerobic cellular respiration, a chemical to power cellular processes. They also contain their own DNA and ribosomes

Golgi Body

A

Stacked flatten sacks that are sites of protien sorting, packaging, and modifiction for use in the cell or export. Protien filled vesicles often fuse with or bud off from the golgi apparatus

Q

Nucleus

A

The nucleus is surronded by a double membrane. Its role is to protect and confine the gentic information{DNA} of the cell. Inside the nucleus is a smaller structure known as the nucleoulus which is the site of ribosome production.

Q

Rough ER

A

A membranous chain of connected and flattended sacs which are coated with ribososmes. This allows the rough ER to synthesise and modify protiens. the rough ER reticulum typically surronds, or is close to, the nucleus

Smooth ER

A

A membranious chain of connected and flattend sacs which are not coated with ribosomes. The smooth ER is responsible for the production of lipids in a cell
