The root cap needs to be continually supplied with new cells by the root apical meristem (RAM) because: Select one: a. the root cap needs to recruit new cells from the RAM to develop lateral root hairs. b. the population of root cap cells needs to be replenished from the RAM as older root cap cells differentiate into epidermal, cortex, and vascular tissues. c. root cap cells are damaged or become separated as elongation in the tissue produced by the RAM forces it through the soil. d. the root cap must add cells to cover the additional surface area created by the growing root tip.   truck driver is transporting a load of unripened bananas in an air-tight vehicle and decides to stop and eat an apple after checking on his cargo. He opens the back of his truck and, while walking around the unripened bananas, he decides the apple is overripe and drops it. When the bananas are finally delivered days later, he is surprised to find that all of his bananas have ripened. Why has this occurred?…
Match the following plant cells and tissues with their definition: - v Collenchyma A. grouped in strands and help support young parts of the plant shoot. They have unevenly thickened primary cell walls. - v Sugar-conducting cells of the phloem B. are alive at maturity, but lack organelles. Each sieve-tube element is connected to a companion cell by plasmodesmata. Water-conducting cells of the xyleem v Sclerenchyma C. The two types of water-conducting cells, tracheids and vessel elements, are dead and lignified at maturity. - v Parenchyma D. rigid due to thick secondary walls containing lignin, dead at functional maturity and play a role in support in the plant. E. cells are flexible and provide the most diversity of functions (such as photosynthesis)
(a) Describe the role of mitosis in the growth of a plant. (b) Explain why there are more cells observed in mitosis in the root tip than in the woody stem.
