Root Anatomy Flashcards
Root apical meristem
mitosis
mucigel
helps reduce friction as root goes through soil
what is mucigel produced by
the dictyosomes of root cap cells
From inside to out how list 3 areas
procambium
ground meristem
protoderm
i think
procambium
center
primary xylem and phloem
protoderm
outside
epidermis
ground meristem
cortex in middle
what is the cortex made of
parenchyma cells
WHat happens to vacuoles in zone of elongation
a few sm vacuoles fuse to one large vacuole
do root epidermal cells have cutin
no
endodermis
band of cells that surrounds the vasc tissue of the root
innermost layer of parenchyma cells
what is suberin
wax (waterproof) that forms casparian strip
casparian strip
regulated the movement of water and nutrients
forces water to move inside cells or vasc tissue
is there a pith in a dicot root
no
Indeterminant growth
plants never stop growing
What type of plants have vasc cambium
woody plants
Do monocots have vasc cambium in roots and stems
no
What is another name for secondary root formation
lateral root formation
Where do new cells grow from in secondary root formation
pericycle
DOes each secondary root have its own root tip and apical meristem
yes
Is secondary growth secondary root formation
no- its primary growth
where does secondary growth occur
zone of secondary maturation
WHat does the vasc cambium do
produces new cells
Xylem 2 types of cells
vessels and tracheids
