- 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.
