Study Notes
Permanent Tissues
- In biology, permanent tissues are a type of tissue that has lost the ability to divide and are specialized to perform specific functions.
Simple Permanent Tissues in Plants
- Examples of simple permanent tissues in plants include parenchyma, collenchyma, and sclerenchyma.
Meristematic Tissues
- The main characteristic of meristematic tissues is that they have the ability to divide and differentiate into different types of cells.
- Meristematic tissues play a crucial role in plant growth as they provide new cells that can differentiate into various tissues, allowing the plant to grow and develop.
- The apical meristem is responsible for the increase in plant height.
- The procambium, a type of meristem, is where sclerenchyma fibers are found.
Sclerenchyma Tissue
- Sclerenchyma tissue is composed of dead cells that provide mechanical strength and support to the plant body.
- Sclereids, a type of sclerenchyma cell, are commonly found in fruits, seeds, and stems of plants.
Plant Tissues
- The most abundant tissue in plants is parenchyma tissue.
