Chloroplasts Pete Tarby Kelley Thornton 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. Main Function PHOTOSYNTHESIS 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. CHLOROPLASTS STRUCTURES Inner & Outer membrane Thylakoids Absorb & Transport Light capturing disc shaped photosynthetic pigments Sunlight & energy 100 + Thylakoid Membrane Contains Chlorophyll Ribosome Stroma Metabolic enzymes Convert CO2 to Carbohydrates Grana Granum Stacked membranes of thylakoids DNA GRANUM FRESH WATER ALGAE CHLOROPLASTS LIVERWORT CHLOROPLASTS DISC SHAPED CHLOROPLASTS DISEASES Tobacco Mosaic Virus Turnip Mosaic Virus DISEASES Tomato Bushy Stunt Disease The following structures can be found in the chloroplast….. a. thylakoid, DNA, crista, granum b. granum, thylakoid, stroma, DNA c. cellulose, grana, thylakoid, stroma d. granum, golgi, stroma, DNA During photosynthesis the sun’s energy is used to convert carbon dioxide and water into….. a.
