Specialized Cells in Plants Xylem, Phloem, Root Caps, and Guard Cells

Specialized Cells Not only do animals (humans) have specialized cells, so do plants. Cell differentiation: the process by which specialized cell types develop a specific function. One plant cell will give rise to a new plant cell with a new function.

xylem Vascular tissue in plants Used for transporting WATER and other nutrients

Phloem Vascular tissue in plants Used for transporting FOOD(sugar aka glucose)

Guard cells Located in the epidermis of plants Purpose: to regulate TRANSPIRATION (the movement and evaporation of water through plants) Closing and opening of stomata

Root caps Covers the tip of the root Cause the roots to grow downward (gravitational pull) If the root cap is removed, the roots will grow in any direction.

Root hairs Absorption of water
