Plant Tissue Types and Functions

Meristematic tissue is responsible for the growth of plant roots and shoots, enabling plants to extend and develop in size.
Cork tissue, a type of protective tissue, forms the outer layer of plant organs, providing insulation and protection from physical damage and pathogens.
Parenchyma, collenchyma, and sclerenchyma are types of permanent tissue, while meristematic tissue, including apical and lateral meristems, is primarily involved in growth; therefore, permanent tissue is not considered a type of meristematic tissue.
The epidermis serves as the protective outer layer of plant organs, playing a crucial role in reducing water loss and deter pests.
Permanent tissue is commonly found in mature regions of the plant, including stems, leaves, and roots, where it performs specialized functions.

Meristematic Tissue

Secondary meristematic tissue enables lateral growth in plants, formed by lateral meristem.
Two main types of secondary meristem: vascular cambium and cork cambium.
Vascular cambium generates phloem (nutrient transport) and xylem (water transport) tissues.
Cork cambium produces the protective outer layer on woody and herbaceous plants.

Primary Meristematic Tissue

Responsible for primary (vertical) growth in plants.
In dicots, primary meristem is located in the apical meristem at the tips of shoots and roots.
In monocots, intercalary meristem is found at nodes, aiding stem growth after damage.
Differentiates into three specialized layers of plant tissue.

Types of Meristems

Three primary types of meristems:
- Apical meristem
- Intercalary meristem
- Lateral meristem
All types regulate mitotic division, where one cell divides into two identical daughter cells.

Characteristics of Meristematic Cells

Unique for being undifferentiated with self-renewal ability.
During division, one daughter cell remains meristematic while the other specializes.
Meristematic cells have thinner cell walls compared to differentiated plant cells.
Characterized by dense liquid in cytoplasm and absence of vacuoles.
Possess a large, prominent nucleus.

Functions of Meristematic Tissue

Primary function is to generate new growth in plants.
Collectively, meristematic cells form meristematic tissue, facilitating growth and development.
Able to create specialized cells that execute specific functions within the plant.

Examples of Meristematic Tissue

Observable in the bark of trees and the fresh growth on shoots and roots.
