Which of the following statements accurately describe meristems? Select each correct answer. a. Apical meristems allow a plant to grow taller above ground and to extend deeper into the ground. b. C. A meristematic cell has the ability to differentiate into one of multiple different cell types. Lateral meristems become active later in the life of a plant and allow an older plant to grow through elongation of the roots and shoots. d. The morphology of woody eudicot stems differs with age due the action of lateral meristems. e. In monocots, secondary growth is a product of apical meristems.

Answer
The following statements accurately describe meristems:
a. Apical meristems allow a plant to grow taller above ground and to extend deeper into the ground.
- Explanation: Apical meristems are responsible for the primary growth of plants, which includes elongation of stems and roots. This growth allows the plant to increase in height and depth.
b. A meristematic cell has the ability to differentiate into one of multiple different cell types.
- Explanation: Meristematic cells are undifferentiated cells that can give rise to various types of specialized cells, contributing to the formation of different tissues and organs in the plant.
d. The morphology of woody eudicot stems differs with age due to the action of lateral meristems.
- Explanation: Lateral meristems, such as the vascular cambium and cork cambium, contribute to secondary growth in woody eudicots, leading to changes in stem morphology over time, including the formation of growth rings and an increase in girth.
Incorrect Statements:
c. Lateral meristems become active later in the life of a plant and allow an older plant to grow through elongation of the roots and shoots.
- Explanation: Lateral meristems are involved in secondary growth and contribute to an increase in girth, not elongation. Elongation is primarily the role of apical meristems.
e. In monocots, secondary growth is a product of apical meristems.
- Explanation: Monocots generally do not exhibit secondary growth, as they lack the lateral meristems that are responsible for secondary growth. Apical meristems are responsible for primary growth in monocots, not secondary growth.
