Photosynthesis SJCHS

Photosynthesis Photosynthesis: C in CO 2 made into glucose

Chloroplasts Chloroplast Outer, Inner membrane Thylakoids: Holds chlorophyll (only reflects green light and absorbs other colors) Stroma: Fluid in inner membrane Has ribosomes, DNA

Photosynthesis

Water saving adaptations C 3 plants: Stomata close when too much water is lost Most common (soy,oats, rice, wheat) C 4 plants: CO 2 still mined when stomata closed Common in dry areas (corn, sugarcane) CAM plants: Stomata opened at night, CO 2 stored and used during the day Common in very dry areas (cacti, pineapples, aloe)
