Why does the Casparian strip form more slowly in some areas? What are these areas called? What is the difference between a root hair and a lateral root? How does the structure of a root hair contribute to its function? What type of environmental conditions might select for a netted root system? Explain your answer.

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.
