Chloroplasts Pete Tarby Kelley Thornton
2
Chloroplasts kloros - 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.
3
Main Function PHOTOSYNTHESIS Photosynthesis Converts carbon dioxide & water into glucose and oxygen. CO 2 + 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.
