Root anatomy, morphology and function

what meristem is behind the rootcap?

what are the three tissues the apical meristem produces?

what is the function of the rootcap

Are cells continuously sloughed off in the root cap as the roots push the ground (True/False)

what region in the root perceives gravity

plastid that is found in the root cap that act as gravity sensors

what meristem produces the rootcap

gives rise to an outer layer of cells that is called the epidermis

produces parenchyma cells to the inside of the cortex

produces primary xylem and primary phloem

absent in most dicots, produces the pith and cortex

4 regions that are in roots

protective layer on root

located behind the root cap, includes apical meristem (protoderm, ground meristem and procambium)

located behind the region of cell division, roots lengthen

located above the region of elongation, primary tissues mature into secondary tissues and where root hairs are formed

what are the three types of tissue found in roots

lacks a stomata and cuticle, outer absorbing surface

thin walled parenchyma cells found to the inside of the epidermis.

loosely packed to allow for water and minerals to move through without entering the cells

functions in food storage

protective layer, lined with suberin slows water and nutrient loss from the root.

slows water and nutrient loss from the root, hypodermal cells are lined with this

what are the two pathways that water and nutrients can travel through the root
