Roots

leaf flower stem roots

fibrous, taproot, storage root, prop

Anchor plant in soil uptake water uptake dissolved nutrients store food reserves

comes from radicle of the embryo and gives rise to the taproot

roots that grow from the primary root

no visible primary root clumps of very thin roots usually in shallow soil. it knits up the soil. ex. grass.

large descending primary root, many secondary roots branching from primary root, typically grow in very deep soil. lots of space for storage ex. carrot

large primary root structure stores food reserves, found on biannual and perennial plants, regenerate vegetative growth after winter, agricultural root crops. ex. beets

growth at region of the tip of the roots

cell mass protecting meristem

outer skin of root

responsible for uptake of water and dissolved nutrients

xylem and phloem; the “plumbing” of the plant

meristematic; growth in girth

internal root tissues for storage

inner most layer of cortex

layer of cells that surrounds vascular tissue

simple permanent tissue in the plants. thin walled and makes up the bulk of the plants soft tissues

uses ATP

uses no ATP

can be anything- movement of particles from areas of higher concentration of areas of lower concentration until equilibrium.

is diffusion of water through a semipermeable membrane separating 2 solutions

water uptake through osmosis

lower H2O concentration outside of cell H2O moves out cell shrinks
