Study Notes
Meristematic Tissues Overview
- Composed of immature, undifferentiated cells that continuously divide.
- Found primarily at shoot and root tips in plants.
Characteristics of Meristematic Tissues
- Consist of small, immature cells.
- Highly active metabolism, characterized by dense cytoplasm.
- Minimal to negligible intercellular spaces.
- Thinner cell walls with distinct, prominent nuclei.
Types of Meristematic Tissues
-
Apical Meristem:
- Located at tips of stems, roots, and branches.
- Responsible for axial (vertical) growth of the plant.
-
Intercalary Meristem:
- Situated at the base of internodes.
- Facilitates growth in the internodal regions.
-
Lateral Meristem:
- Found on the lateral sides of stems and roots.
- Responsible for radial (width) growth of the plant.
- Includes vascular cambium and cork cambium as examples.
Meristematic Tissues
- Defined as a group of immature and actively dividing cells located at specific regions in plants.
- Essential for plant growth and development, primarily found in shoot and root tips.
Characteristics of Meristematic Tissues
- Composed of undifferentiated cells, allowing for growth and development.
- Cells are small and metabolically active, featuring dense cytoplasm.
- Minimal to no intercellular space between cells.
- Thinner cell walls that allow for flexibility, with a prominent nucleus.
Types of Meristematic Tissues
-
Apical Meristem:
- Located at the tips of stems, roots, and branches.
- Responsible for vertical/axial growth (increasing height).
-
Intercalary Meristem:
- Found at the base of internodes.
- Facilitates growth in the internodal regions, contributing to lengthening of stems.
-
Lateral Meristem:
- Positioned on the sides of stems and roots.
- Responsible for radial growth (increasing thickness).
- Includes vascular cambium and cork cambium.
