Concept explainers
To explain: The number of times must each meristem cell divide to produce the 100 cells in the given observation.
Introduction: The plants are mainly multicellular, predominantly photosynthetic eukaryotes of the kingdom Plantae. The meristem is a tissue in the plants that consists of undifferentiated cells, which is capable of cell division.
Explanation of Solution
The meristem is classified by their location in the plant as lateral (in vascular and cork cambia), apical (located at shoot and root tips), and intercalary (at internodes). The root apical meristem is also called root apex. The root apical meristem is a small region at the tip of root in which all cells have the ability of repeated division and from which all the primary root tissues are derived.
Each time a meristem cell divides, one daughter cell contributes to a new tissue and others continue as meristem cell. Therefore, each meristem cell would have to divide 10 times for every 100 root cap cells that need to be replaced.

- 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.
