geotropism
turgor pressure
4
When comparing animal cells to plant cells, all of the following are unique to plants cells, except
chloroplast
cell wall
chlorophyll
cell membrane
5
How has the seed dispersal method developed by this plant given it a reproductive advantage?
the method lengthens the life cycle of each of these plants
the method reduces the chance that herbivores will consume the seeds
Method ensures that offspring will be dispersed and reduces competition
the method reduces the plants' need for water and other nutrients
6
Which of the following correctly identifies the roles of chloroplasts and chlorophyll in photosynthesis?
chloroplasts and chlorophyll are responsible for transpiration
chlotoplast absorb light energy, chlorophyll make CO2 from the energy
chloroplasts cellular respiration takes place, chlorophyll photosynthesis
chloroplasts are the site of photosynthesis, chlorophyll absorb light
7
What is the function of xylem
transports water and minerals up from the roots
forms a protective layer on the 2nd year perennials
transports sugars down from the leaves
gas exchange on the ventral side of the leaf
8
During its growing season, a corn plant can lose around 125L of water. What is a major source of this water loss? ?
diffusion of water from the roots to the surrounding soil
movement of water through the root hairs into the soil
leakage due to cells rupturing from osmotic pressure
transpiration from opening on the underside of the leaves
9
Which system carries cytokinins produced in the roots to the rest of the plant?
None
dermal system
reproductive system
vascular system
10
Which of these must happen for corn seeds to develop on the ear?
pollen must be transported to the silk through the phloem
more tassels than silks need to be present in the same plant
the tassels must come into direct contact with the silks of the ears
pollen grains must fall from tassels and land on the silks of the ear
11
fruits contain specialized structures that are adaptations for _
synthesizing new proteins
attracting pollinating insects
growing tall
aiding in seed dispersal
12
Which of the following most closely explains how plants obtain energy?

conversion of sugar into cellulose
13
What would most likely cause the closing of the stomata wouid most likely be caused by?
a reduced supply of oxygen
long periods of rainfall
little available rainwater
high concentrations of glucose
14
What is the function of phloem
gas exchange on the ventral side of the leaf
transports sugars down from the leaves
forms a protective layer on the 2nd year perennials
transports water and minerals up from the roots
15
What effect do hormones have on plants responding to stimuli?
they increase or decrease cell growth
they cause each cell to bend
they make the cell walls more rigid
they increase the rate of photosynthesis
16
The cuticle of a plant
the extracellular, waxy layer that prevents water loss from the plant
the vascular tissue that carries water, nutrients, and hormones
is the area(s) of the plant where new growth occurs
the simple carbohydrate that is produced by cells and provides energy
17

glucose, plasma membrane
cellulose, cell wall
glycogen, plasma membrane
sucrose, cell wall
18
Which statement best explains the importance of the root hairs to the stems and leaves of the plant?
root hairs stop water loss in leaves through transpiration and gas exchange
root hairs decrease the need for osmosis and diffusion in vascular tissue
root hairs increase the surface area for nutrient and water absorption
root hairs convert minerals into glucose for immediate use by cells
19
