Intercalary Meristem
Located between mature tissues, responsible for regeneration and growth in grasses.
What is Intercalary Meristem?
A tissue composed of actively dividing cells responsible for plant growth.
Key points
- Identify the location and function of intercalary meristems.
- Differentiate intercalary meristems from other meristematic tissues.
- Explain the significance of intercalary meristems for plant survival, especially in grasses.
Common exam trap
Confusing intercalary meristems with apical meristems (both cause elongation but differ in location and persistence).
Definitions
- Term
Meristematic Tissue
- Meaning
A tissue composed of actively dividing cells responsible for plant growth.
- Term
Permanent Tissue
- Meaning
Tissues derived from meristematic tissues that have lost their power of division and have taken up specific functions.
- Term
Node
- Meaning
The part of a plant stem where a leaf is attached.
- Term
Internode
- Meaning
The part of a plant stem between two nodes.
Learning objectives
Identify the location and function of intercalary meristems.
Differentiate intercalary meristems from other meristematic tissues.
Explain the significance of intercalary meristems for plant survival, especially in grasses.
Prerequisites
Basic understanding of plant cell structure.
Knowledge of meristematic tissues (apical, lateral).
Understanding of plant growth and development.
Common mistakes
Confusing intercalary meristems with apical meristems (both cause elongation but differ in location and persistence).
Confusing intercalary meristems with lateral meristems (which cause increase in girth).
Assuming intercalary meristems are present in all plant types.
