Study Notes
Plant Internal Structure and Tissue Systems
- Plant anatomy studies the internal structure of plants
- Plants are made of cells, tissues, and organs
- Different plant organs have different internal structures
- Monocots and dicots have anatomical differences
- Internal structures adapt to different environments
Tissue Systems
- Three types of tissue systems in plants: -Epidermal tissue system -Ground tissue system -Vascular tissue system -Tissue structure and function vary based on location
Epidermal Tissue System
- Forms the outermost covering of the plant
- Includes epidermal cells, stomata, and trichomes (hairs)
- Epidermis is a single layer of compactly arranged cells -Cells are parenchymatous with a large vacuole
- Cuticle (waxy layer) prevents water loss (except in roots)
- Stomata regulate transpiration and gas exchange -Guard cells control stomatal opening/closing -Subsidiary cells surround stomata -Stomatal apparatus includes guard cells and subsidiary cells
- Trichomes (hairs) on stems and roots -Root hairs absorb water and minerals -Shoot trichomes prevent water loss, may be secretory.
Ground Tissue System
- All plant tissues except epidermis and vascular bundles
- Composed of simple tissues (parenchyma, collenchyma, sclerenchyma)
- Parenchyma cells are in cortex, pericycle, pith, and medullary rays.
- Leaf mesophyll is the ground tissue in leaves (chloroplast-containing cells)
