Explanation / Answer

1. Root hairs are thin extensions of epidermal cells whereas lateral roots arise from the pericycle and they extend horizontally from the primary root. So, the correct option is option A, root hairs are thin extensions of epidermal cells. Lateral roots are organs.

2. Vascular cylinder is made up of xylem and phloem tissue. Water and minerals travel through xylem from roots to the shoot of a plant. So, the correct option is option D, Vascular cylinder.
