Study Notes
- Shoot system consists of vegetative (non-reproductive) parts like leaves and stems, and reproductive parts like flowers and fruits.
- Root system provides support to plants, absorbs water and minerals, and is usually underground.
- Meristematic tissue is undifferentiated and contributes to plant growth through cell division.
- Different types of meristematic tissue include apical (tips of stems and roots), lateral (girth or thickness growth), and intercalary (length increase in monocots).
- Permanent tissues like dermal (protection, gas exchange), vascular (transportation), and ground (photosynthesis, support, storage) tissues no longer actively divide.
- Trichomes are epidermal outgrowths that reduce transpiration and protect against herbivory, while root hairs facilitate water and nutrient uptake.
- Stomata are openings that allow gas exchange in plants, regulated by guard cells to control carbon dioxide uptake and water loss.
