The waxy waterproof coating on stems and leaves of plants that prevent water loss
|
cuticle
|
|
a broad, flat structure of a plant that traps light energy for photosynthesis
|
leaf
|
|
pores of the leaf. openings in the cuticles of leaves that control water loss
|
stomata
|
|
cells that controll the size of the openings in the stomata according to the amount of water in the plant.
|
guard cells
|
|
loss of water through the stomata
|
transpiration
|
|
a plant organ that absorbs water and minerals from the soil, transports the nutrients to the stem, and anchors the plant in the ground
|
root
|
|
provides structural support for upright growth and contains tissues for transporting food, water, and other materials.
|
stem
|
|
tissues that provides a covering for the plant.
|
dermal tissues
|
|
tissues that transport food and water throughout the plant.
|
vascular tissues
|
|
tissues that produce and store food.
|
ground tissues
|
|
produce new growth
|
meristems
|
|
plant tissue composed of tubular cells that transport water and minerals from the roots to the rest of the plant.
|
xylem
|
|
made up of a series of tubular cells that are still living and transport sugars from the leaves to all parts of the plant.
|
phloem
