Ways to absorb water via Root: Symplast
Cell to Cell
Way to absorb water via root: apolast
Water flows in between Cells to the casparian strip.
Modified Roots: Pheumatophores
Snorkles, Better gas exchange for Underwater Plants.
Modified Roots: Aerial
Roots get water from the air
Modified Roots: Reproductive
Other Individuals grow out of Roots
What is a plant?
Non motile, Life cycle is alternation of generations, photosynthesis, Eukaryote.
Non Vascular Plants
Moss. No xylum, no phloem, Majority of life in is Gametophyte
Seedless Vascular Plants
Ferns. Have xylem. Makes a lot of spores.
Gymnosperms
First Seed Plants, No flowers, no fruit. Pine Tree.
Angiosperms
True Flowering Plant. Very effective xylem and phloem.
Angiosperms: Monocot
