adventitous roots
from base of stem

27
Q

adventitous roots

A

also fiborous roots from base of stem

28
Q

lateral roots

roots off of adventitious roots

29
Q

plant morphology

A

study of structures of external features

study of the structure of the internal features cellular and molecular levels

31
Q

What is the root cap made of

A

thin parenchyma cells

32
Q

function of root cap

A

push through soil
protect apical meristem

33
Q

zone of division what is found in it

A

apical meristem

34
Q

zone of elongation

A

where cells elongate

35
Q

what is zone of primary maturation also known as

A

root hair zone

36
Q

what do root hairs do

A

increase SA
easy wat to get water, not a lot of energy

37
