Roots Flashcards
4 major plant parts
leaf flower stem roots
types of roots
fibrous, taproot, storage root, prop
function of roots
Anchor plant in soil
uptake water
uptake dissolved nutrients
store food reserves
primary roots
secondary roots
fibrous roots
no visible primary root
clumps of very thin roots
usually in shallow soil. it knits up the soil.
ex. grass.
tap roots
large descending primary root, many secondary roots branching from primary root, typically grow in very deep soil. lots of space for storage
ex. carrot
storage roots
large primary root structure stores food reserves, found on biannual and perennial plants, regenerate vegetative growth after winter, agricultural root crops.
ex. beets
apical meristem
growth at region of the tip of the roots
root cap
cell mass protecting meristem
epidermal cells
outer skin of root
root hairs
responsible for uptake of water and dissolved nutrients
vascular tissue
xylem and phloem; the “plumbing” of the plant
cambium
meristematic; growth in girth
cortex
internal root tissues for storage
