Structure of Chloroplast

Double membrane, thylakoid memb. arranged in stacks called granum/grana, chlorophyll on thylakoid, thylakoid filled with fluid containing enzymes for water photolysis for photosyn., stroma has 70s ribosomes+DNA+RNA+enzymes+starch grains+lipid droplet

1 of 6

Cuticle + upper epidermis

transparent, no chloroplasts, allow light to pass through

2 of 6

Palisade layer

closely packed, many chloroplasts, max. light absorption

3 of 6

Spongy layer

air spaces between, allows diffusion of gases via stomata to and from photosynthetic cells

4 of 6

Vein (midrib)

Xylem+phloem: transports water to photosynthetic cells, transports made food as sucrose and amino acids to other parts

5 of 6

thin leaf

distance for diffusion is small so faster
