Key Topics to Revise

1

Introduction to Tissues

  • A tissue is a group of cells similar in structure and/or work together to achieve a particular function
  • Multicellular organisms show division of labour - different groups of cells perform different functions
  • Specialised cells grouped together form tissues for maximum efficiency
2

Differences Between Plant and Animal Tissues

  • Plants are stationary, animals move - this affects their tissue structure
  • Plants have more supportive tissue (often dead cells) to remain upright
  • Animals have more living tissues as they need more energy for movement
3

Plant Tissues - Meristematic Tissue

  • Located only at specific growing points in plants
  • Cells are very active with dense cytoplasm, thin cell walls, prominent nuclei
  • Lack vacuoles (to allow space for rapid division)
4

Plant Tissues - Simple Permanent Tissue

  • Formed from meristematic tissue after differentiation
  • Three main types: Parenchyma, Collenchyma, and Sclerenchyma
  • Parenchyma: most common, thin-walled living cells, stores food
