ANATOMY OF FLOWERING PLANTS

Image
  What is Plant Anatomy? Plant anatomy is the study of internal structure and organization of tissues in plants. It helps in understanding: Functional adaptation Transport system Growth patterns Tissue Organization in Flowering Plants Flowering plants have three major tissue systems :  Epidermal Tissue System Components: Epidermis Single layer of compact cells No intercellular spaces Covered by cuticle (except roots) Cuticle Made of cutin Prevents water loss Stomata Present mainly on leaves Composed of guard cells Regulate: Gas exchange Transpiration Root hairs Extensions of epidermal cells Increase surface area for absorption Trichomes (in stem) Hair-like structures Protection + reduce transpiration  Functions: Protection Water conservation Gas exchange 🌿 B. Ground Tissue System  Types of Ground Tissue: 1. Parenchyma Living cells, thin cell wall Large vacuole Functions: Storage Photosynthesis ( chlorenchyma ) Air storage ( aerenchyma ) 2. Collenchyma Living cell...
