2) Most of the growth and cell division takes place in a collection of cells called the apical meristem. From an evolutionary standpoint, why would it make sense for the root to be able to continually over the course of the plant's lifecycle? 3) The vascular tissue in plants is similar to the human circulatory system in that its function is to carry fluid all over the plant. Vascular tissue in the plant is comprised of xylem and phloem tissues with the cells being larger and essentially dead at maturity. Why do you think that is given that the xylem carries water and the phloem carries sugars. 4) Name and describe the key differences in monocots and eudicots, focusing on the veins in the leaves, the arrangement of the vascular tissue in the stem and the number of cotyledons.
