Watertransport
Root hairs = small hairs on the roots which the plant uses to absorb water and minerals.

Vessels = thin tubes through which water and dissolved substances are transported (located in vascular bundles).
  • Xylem (pronounced: zai-luhm):   roots → leafs
  • Phloem (pronounced:flow -em) : leafs → roots and flowers

Slide 11 - Tekstslide

Stomata
Stomata = small openings in the leaf through which substances can pass.

Slide 14 - Tekstslide

Why do trees shed their leaves?
Evaporation takes place through leaves.
Roots don't work well in the cold.

Abscission layer = layer between tree and petiole, so that less water and minerals reach the leaves in autumn.

Layer of cork = layer on the place where the leaf has fallen (against water loss and pathogens).

Leaf scars = Place where the leaf used to be attached to the branch.

Plastids
Dye granules = granules with dye in a plant cell.
  • Green (chloroplasts = for making nutrients)
  • Red, yellow or orange (chromoplasts)
  • Colorless (starch granules = starch is stored here)
