SCIENCE SPECIALIZED TISSUES IN PLANTS
roots
Absorbs water and minerals from the ground. Anchors plant in ground.
Stems
Carry substances between roots and leaves; provide support for plant; holds leaves up to sunlight
Trichomes
Give leaf a fuzzy appearance, help reduce the evaporation of water from the plant.
STEMS TRANSPORTING SYSTEM
MUST CONTAIN SUBSYSTEMS THAT CAN LIFT WATER FROM ROOTS UP TO THE LEAVES AND CARRY THE PRODUCTS OF PHOTOSYNTHESIS FROM THE LEAVES BACK DOWN TO THE ROOTS.
THREE OF THE PRINCIPAL ORGANS OF SEED PLANTS ARE
ROOT, STEMS AND LEAVES
leaves
The main photosynthetic organs of vascular plants.
dermal tissue
The outer covering of a plant, consisting of a single layer of epidermal cells. also outer covering covered with a thick waxy layer coating.
The two types of vascular tissue in most plants are
Xylem and phloem
*Plants consist of three main tissue systems:
dermal tissue, vascular tissue, ground tissue
guard cells
on the underside of leaves, regulate water loss and gas exchange
vascular tissue
specialized tissue in plants that carries water and nutrients throughout the plant.
