All About Plant Tissues!
Introduction to Plant Tissues
Tissues are groups of similar cells that work together to do a specific job. Plants need tissues to grow, stay
strong, make food, and carry water!
Types of Plant Tissues
A. Meristematic Tissues - The Growers!
- Found in tips of roots and stems
- Keep dividing to help the plant grow
- Types:
- Apical (top growth)
- Lateral (width growth)
- Intercalary (in grasses)
B. Permanent Tissues - The Helpers!
These don't divide anymore. They help the plant with support, food storage, and transport.
Simple Permanent Tissues
- Parenchyma: Stores food and water, has large vacuoles, soft and flexible
- Collenchyma: Supports young parts, has thick corners
- Sclerenchyma: Very hard, dead cells, found in nutshells and stems
Complex Permanent Tissues
- Xylem - The Water Carrier:
- Carries water and minerals from roots
- Made of vessels, tracheids, fibers, parenchyma
