What is a halophyte?
Aquatic Plant
Heat tolerant Plant
Salt tolerant plant
Cold tolerant plant
I. To get rid of excess CO2
II. To allow transpiration
III. To exchange gases with the environment
Why is transpiration an inevitable consequence of gas exchange in the leaf?
Water creates a hypertonic environment in the leaf, but hypotonic environment everywhere else in the plant
When stomata open, only molecules containing oxygen may enter or leave the leaf
When stomata open for carbon dioxide absorption, water vapor leaves simultaneously
When stomata open for oxygen absorption, water vapor leaves simultaneously
What is the function of root hair?
it is a place to store the food and gas
it increases surface area to absorb more water
Which of these is TRUE?
Xylem carries water and dissolved minerals up the plant
Phloem carries water and dissolved minerals up the plant
Stomata carry water and dissolved minerals up the plant
When photosynthesis takes place during the day, stomata will...
open
close
What is the name of the part of the root that allows water and minerals to enter?

root hairs
phloem
phyla
Water and minerals move in which direction within the plant
Upward
Down
What part of the leaf prevents water loss?
Spongy mesophyll
Palisade mesophyll
Waxy cuticle
Xylem
Within a leaf, chloroplasts are found in abundance within the
Waxy cuticle
Guard cells
Xylem tissue
Palisade mesophyll
Which of the following is not an adaptation of a xerophyte?
Reduced leaves
Rolled leaves
Stomata in pits
Salt excretion
Within a stem, the vascular bundle is made up of
pith and cortex
guard cells
xylem and phloem
mesophyll cells
Guard cells are responsible for
protecting the roots from water loss
producing glucose for plant growth and metabolism
controlling the opening and closing of the stomata
producing xylem
