Cell Function:
Waxy cuticle- prevents water loss
Upper epidermis- thin --> allows light to absorb through efficiently to the palisade cells for photosynthesis
Palisade cells- numerous chloroplasts --> for photosynthesis
Chloroplasts-
Waxy cuticle- prevents water loss
Upper epidermis- thin --> allows light to absorb through efficiently to the palisade cells for photosynthesis
Palisade cells- numerous chloroplasts --> for photosynthesis
Chloroplasts-
- arranged in the best place to collect the maximum amount of sunlight
- typically disk shape
- chlorophyll for photosynthesis to occur
- chloroplast envelope (highly selective in what enters & leaves chloroplast)
- has a stroma (colourless matrix)
- starch grains --> E store for CBH during photosynthesis
Spongy layer- allows air to circulate
Lower epidermis- Stoma- allows gas exchange when open (guard cells spread apart) Xylem- transports water Phloem- transports glucose & minerals |
