Chloroplastskloros - green plastos - formed

• Endosymbiosis Theory - Came from Prokaryotes• Only Found in Plant Cells & Some Protists – Algae• Reproduce through Cell Division• Organelle – Pigment Containing Plastid• Capture light energy to produce food for the cell.• Create their own food by making sugars & starches.

Main FunctionPHOTOSYNTHESIS

Photosynthesis Converts carbon dioxide & water into glucose and oxygen.

CO2 + Water Sugar + Oxygen

Chlorophyll - Pigments in thylakoids.Traps sunlight and gives plants green color.

Generate ATP - Adenosine Triphosphate

Power transport across cell membranes and movement of cells.
