Photosynthesis

• In photosynthesis, green plants use light energy to make carbohydrate.
• Photosynthesis occurs in the chloroplast.
• The role of photosynthesis is to provide food and oxygen for all organisms.
• 6C0, + 6H,0 + light + chlorophyll > C,H,206 + 60г.
• The light stage of photosynthesis needs light and occurs in the granum of the chloroplast.
• The dark stage of photosynthesis does not need light and occurs in the stroma of the chloroplast.
• The products of the light stage of photosynthesis are ATP and NADPH, which are used in the dark stage.
• The by-product of the light stage of photosynthesis is 0г, which is used in plant respiration or released into the air.
• The structure of a chloroplast consists of the stroma (dark stage) and the granum (light stage).
• The pathways of the light stage of photosynthesis include pathway 1 - cyclic electron flow and pathway 2 - non-cyclic electron flow.
