Plant Tissue Overview

Plant Tissue Overview

Plant tissue is a group of similar cells that perform a specific function in a plant.

Types of Plant Tissue

Meristematic Tissue

• Consists of undifferentiated cells that can divide and differentiate into various types of cells
• Found in areas of growth such as tips of stems and roots
• Functions: growth, differentiation, and development

Permanent Tissue

• Consists of differentiated cells that have lost the ability to divide
• Can be classified into three main types: simple, complex, and specialized tissues

Simple Tissues

• Parenchyma Tissue
  • Consists of living cells with thin walls
  • Functions: storage, photosynthesis, and secretion
• Collenchyma Tissue
  • Consists of living cells with thick walls
  • Functions: support, structure, and flexibility
• Sclerenchyma Tissue
  • Consists of dead cells with thick walls
  • Functions: support, protection, and structure

Complex Tissues

• Xylem Tissue
  • Consists of tracheids, vessels, and xylem parenchyma cells
  • Functions: transport of water and minerals from roots to leaves
• Phloem Tissue
  • Consists of sieve cells, companion cells, and phloem parenchyma cells
  • Functions: transport of sugars and other organic compounds from leaves to roots

Specialized Tissues

• Epithelial Tissue
  • Consists of cells that cover the surface of the plant
  • Functions: protection, absorption, and secretion
• Muscle Tissue
  • Not found in plants
• Nerve Tissue
  • Not found in plants

Functions of Plant Tissue

• Support and structure
• Transport of nutrients and water
• Storage of food and water
• Photosynthesis
• Protection and defense
• Secretion and excretion
