Question

Single maize root apical meristem gives rise to more than ______ cells/hour.

Options

• 20500

• 19500

• 18500

• 12500

• 17,500

Answer 1

Single maize root apical meristem gives rise to more than 17,500 cells/hour.

Explanation:

Growth in plants is often measured by the increase in cell number. In maize, the root apical meristem consists of actively dividing tissues that use rapid mitosis to produce new cells, allowing the root to quickly elongate and explore the soil for water and nutrients.
