Plant tissues are multicellular eukaryotes that have tissue systems made up of different cell types that perform specific functions. These plant tissues are made up of similar cells that each serve a specific purpose. Organs are formed when tissue types combine. Each organ is also tailored to a specific function.
They are divided on their basis of ability:
- Meristematic tissue.
- Permanent tissue.
Meristematic Plant Tissues:
Made up of cells with the ability to divide. These tissues are made up of small, cuboidal, densely packed cells that divide to form new ones. As they mature, these tissues can stretch, enlarge, and differentiate into other types of tissues.
Types of Meristematic tissue includes;
- Apical Meristem
These are located at the tips of the roots and shoots and contribute to the plant’s ability to grow taller. Different cell divisions aid in cellular enlargement and the growth of the cells in the roots and shoots.
- Intercalary Meristem
These contribute to the internodes lengthening. It is situated at the intercalary location in the leaves and internodes and increases the plants height, it is a component of the apical meristem.
- Lateral Meristem
It is found in the lateral side of the stems and roots. The plant becomes thicker as a result. The two lateral meristems are the vascular cambium and the cork cambium.
Permanent Tissues:
Derived from meristematic tissues and have lost their ability to divide. These are further divided into two types;
- Simple Permanent Tissues.
These also go by the name of homogeneous tissues. They are composed of just one kind of cell, typically with the same origin, makeup, and purpose.
- Complex Permanent Tissues
Heterogeneous, or made up of various cell types, are complex permanent tissues. All types of cells behave as one cohesive unit in these tissues, which serve as conducting tissues. Because they are made of vascular bundles, these tissues are also known as vascular tissues.
