Study Notes
Tissues Overview
- A tissue is a group of similar cells working together for a specific function.
Plant Tissues
- Plant tissues provide structural support, differing from animal tissues due to plants' fixed habits.
Meristematic Tissues
- These tissues actively divide throughout a plant's life, located in growth regions like root and shoot tips.
- Meristematic tissues are living and contribute to the increase in plant length and girth.
Types of Meristematic Tissues
- Apical Meristem: Found at the tips of stems and roots, aiding in vertical growth.
- Intercalary Meristem: Located at the base of leaves or internodes, contributing to growth in length.
- Lateral Meristem: Found on the sides of stems and roots, responsible for growth in thickness.
Permanent Tissues
- Composed of cells that do not divide; possess permanent structure, size, and function.
- Formed from meristematic tissues after cell division stops.
Simple Permanent Tissues
- Comprised of one cell type.
- Parenchyma: Basic tissue, storage of food, provides support, characterized by thin-walled and loosely packed cells.
- Collenchyma: Living, elongated cells with thickened corners; found in leaf stalks, provides mechanical support and elasticity.
- Sclerenchyma: Thick-walled and lignified cells, offering strength and support under stress, present in stems and seeds.
Complex Permanent Tissues
- Made up of multiple cell types.
- Xylem: Vascular tissue responsible for water and mineral transport; known as wood.
- Phloem: Vascular tissue responsible for food transportation from leaves to other plant parts.
- Different Components of Xylem:*
- Tracheid: Long, narrow, dead cell facilitating water movement.
- Vessel: Wide, dead cell with sieve plates for efficient water passage.
- Xylem Fiber: Provides structural support, long and thick-walled.
- Components of Phloem:*
- Phloem Parenchyma: Living cells that store food.
- Companion Cell: Assists in regulating sieve tube function.
- Sieve Tube: Living cells for food transport, characterized by perforated end walls.
Features of Plant Tissues
| Tissue | Features |
|---|---|
| Parenchyma | Thin-walled, large vacuoles, loosely packed |
| Collenchyma | Elongated cells with thickened corners, provides support |
| Sclerenchyma | Thick-walled, lignin deposition, provides strength |
| Xylem | Dead cells, transports water and minerals |
| Phloem | Living cells, transports food |
