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
