How is the structure of cells in a root's transport system different from the structure of cells making up the epidermis?

∙ 10y ago
The plant's epidermis consists of three main cell types, pavement cells, guard cells, and trichomes. Pavement cells protect the plant body from the dry atmosphere and UV-rays. Guard cells are used for gas exchange in and out of a plant. Trichomes help increase the rate of water absorption and reduce the rate of water loss due to evaporation in order to keep the leaf surface cool. Trichomes also provide a defense against insects since the "hairiness" of the leaf impedes insect infestation. Also Glandular or secretory hairs provide a chemical defense against potential herbivores.
The vascular tissue also called the root's transport system is made up of xylem cells that transport water.

Why is graphite a good lubricant and diamond is an excellent abrasive?
