Meristematic Tissues
Tissues with actively dividing cells, responsible for primary and secondary growth in plants.
What is Meristematic Tissues?
A plant tissue composed of undifferentiated cells that are capable of active division, contributing to plant growth.
Key points
- Define meristematic tissue.
- Identify the characteristics of meristematic cells.
- Classify meristems based on location and function.
- Explain the role of meristems in plant growth.
Common exam trap
Confusing meristematic tissue with permanent tissue.
Definitions
- Term
Meristematic Tissue
- Meaning
A plant tissue composed of undifferentiated cells that are capable of active division, contributing to plant growth.
- Term
Primary Growth
- Meaning
Increase in the length of a plant organ, primarily due to the activity of apical and intercalary meristems.
- Term
Secondary Growth
- Meaning
Increase in the girth or diameter of a plant organ, primarily due to the activity of lateral meristems.
Learning objectives
