Casparian strips are made from endodermal cells that are thickened with \(\underline{\hspace{1cm}}\)and \(\underline{\hspace{1cm}}\).

Difficulty Level: Medium

Report 4 / 5

Which of the following is correct about endodermis?

I.		Separates the cortex with vascular cylinder

II.		Endodermal cells are loosely arranged

III.		Allows water and mineral salts absorbed from the soil to enter the vascular cylinder

IV.		Involves secondary growth and the formation of lateral roots

Difficulty Level: Hard

Report 5 / 5

Which of the following is correct?

	Structure	Adaptation
(A)	Endodermis	Involved in secondary growth and the formation of lateral root
(B)	Epidermis	Have suberin or lignin thickening at the walls which forms Casparian strips to allow water and mineral salts to enter the vascular cylinder
(C)	Cortex	Has thin cell walls to facilitate water movement in the roots

Difficulty Level: Hard
