Summary Introduction
Concept introduction: Root hair is the hair-like outgrowth of a plant root that absorbs the water and minerals from the soil. The important function of the root hairs is the collection of water and mineral nutrients present in the soil and takes them through the roots to the rest of the body. The root hairs do not have chloroplast as it does not carry out photosynthesis.

- Which of the following statements are true for root endodermis?I. Endodermal cells constitute the innermost layer of root cortex and surrond the vascular cylinder (xylem and phloem). II. Endodermal wall is covered with waxy layer of casparian strip which blocks apoplastic transfer of minerals.III. Due to presence of casparian strip, water and minerals can only eneter the vascular cylinder if they will be able to cross the plasma membrane of an endodermal cell.arrow_forwardThe Casparian strip… I. is a waxy layer in the walls of the endodermal cells of the root II. promotes apoplastic movement of water and minerals across the endodermis III. provides an opportunity for regulation of mineral uptake by the plantarrow_forwardDetermine which of the following statements is/are true for root endodermis?

Select one: a. They are found in the zone of cell elongation and help the root to fix nitrogen. b.They are found in the root cap and help the root sense gravity. c.They are found in the zone of cell division of the root and help anchor the plant in the soil. d.They are found in the root apical meristem and help the root to absorb water. e.They are found in the zone of cell differentiation in the root.

The region found above the region of cell division can be seen in different young roots because of the presence of numerous root hairs that increase absorption. III. The meristematic region is has cells that elongate several times their original length and push the root tip through the soil. IV. The meristematic region is the growing apex of the rootarrow_forwardThe structure of the C4 leaf shows a. how mesophyll cells hug the epidermis of the leaf. hug the bundle sheath cells. b.
