Leaf And Crap Flashcards
Hypertonicity?
There is more solute outside than inside. There is more water inside that outside.
Isotonic?
The solute inside and outside of the leaf is balanced. The water is also balanced.
Hypotonicity.
The solute inside is higher than the solute content outside. The water inside is lower than the content outside.
What is the epidermal cell?
Form protective layer. One cell thick. Transparent. No chloroplasts
Cuticle.
Covers epidermal. And prevents evaporation of water. Waxy. Secreted.
Palisade tissue cell
Located underneath upper layer.
Contains most chloroplasts.
Important photosynthesis. Green
Spongy mesophyll
Below palisade. Loose.
Help exchange gasses.
Stomata and guard cells
Small openings in epidermal layer.
Allows water to enter and leave.
Located mostly on underside.
2 lips.
Vascular tissue cells?
Series of tubes that transport fluid.
Xylem. Phloem.
Phloem.
Carries sugar produced in leaves to other parts of the plant.
Xylem?
Thick walled tubes. Inside.
Cohesion in water?
Water molecules are attracted to other water molecules.
Adhesion.
Water molecules are attracted to other substances.
Root pressure.
Dissolved minerals enter xylem cells through active transport. Dissolve minerals create hypotonic situation. Forcing more water in.
Lenticel?
Natural openings found on the stems of trees. Herbaceous. Provide path for gas exchange.
