CELL ORGANELLES

Mitochondria Transfers energy to

ATP which powers most of the cell’s reactions

“Powerhouse” of the cell

Ribosomes

The site where proteins are made

Found of the rough E.R.

Endoplasmic Reticulum Prepares

proteins for export and synthesizes steroids

Rough ER makes proteins in ribosomes, they leave in vesicles and go to the Golgi apparatus

The Cytoskeleton

The system of microscopic protein fibers that supports the shape of a cell

Function in cell structure and movement

Golgi Apparatus Processes and

packages

substances

produced by

the cell

Lysosome A vesicle that

digests

molecules & old organelles

Chloroplast Enables

plants to make carbs from carbon dioxide and water

Cilia and Flagella Hairlike structures that enable cell

movement or move substances across a cell’s surface

Examples:

Cilia Flagella

Respiratory tract Bacteria cell

Features unique to plant cells Cell walls Plastids Central vacuoles

Central Vacuole

When filled with water; keeps plant cells rigid

Also stores waste, enzymes, pigments, toxins etc.

Plastids-contain their own DNA Include chloroplasts, chromoplasts, and

leucoplasts
