Plants Flashcards
what are the three parts of a plant
dermal tissue
vascular tissue
ground tissue
what is dermal tissue
the outer covering of a plant which consists of epidermal cells
what do epidermal cells make up
dermal tissue
what is the waxy outermost layer called
cuticle
what is the cuticle
a non-cellular protective layer produced by the epidermal cells
what does the cuticle do
helps protect the plant against water loss and injury
what are trichomes
- epidermal cells have these projections
- help protect leaf and gives fuzzy appearance
what are guard cells
- regulate water loss and gas exchange
- located on the underside, dermal tissue
what is found in root dermal tissues
root hair cells
what are root hair cells
provie a large number off surface area and aid in water absorption
what do vascular tissues form
a transport system that moves water and nutrients throughout the plant
what are vascular tissues made of
xylem - water conducting tissue
phloem - food conducting tissue
plants contain what which cells specialized to conduct water
tracheids
what are tracheids
make up xylem - transport system that carries water from the roots to every part of plant
what are the two types of xylem cells
- tracheids
- xylem vessel
