- plant tissues
- epidermal tissues
- waxy cuticle (top layer of leaf)
- reduces water loss from leaf
- guard cells and stomata
- guard cells open and close the stomata to control water loss
- allow for gas exchange (o2 and co2)
- waxy cuticle (top layer of leaf)
- palisade mesophyll
- palisade cells
- cells near the top surface of the leaf that are packed with chloroplasts that contain chlorophyll
- both adaptations maximise photosynthesis
- palisade cells
- spongy mesophyll
- air spaces in the leaf between cells
- increased surface area for gas exchange so that co2 can diffuse into photosynthesising cells
- air spaces in the leaf between cells
- xylem
- transpiration- dead cells
- carry water and minerals
- flows in one direction
- cell walls strengthened by lignin
- phloem
- translocation -living cells
- carries glucose
- flows in both directions
- cells have end plates with holes
- meristem tissue
- new cells are made here including root hair cells
- can differentiate into any cell type throughout the life of a plant
- epidermal tissues
