Answers
1
How is water carried through the plant?
phloem
xylem
2
What processes move particles from a high concentration to a low concentration?
diffusion and osmosis
osmosis and active transport
diffusion and active transport
osmosis and photosynthesis
3
The correct equation for photosynthesis is:
carbon dioxide+water-----glucose+oxygen
glucose+oxygen------carbon dioxide+water
glucose+carbon dioxide------oxygen+water
water+sunlight------carbon dioxide
4
Most chloroplasts are found in the ....
cuticle
palisade cells
stomata
spongy cells
5
The phloem carries
glucose and starch
wind
water
6
How is water lost from the leaves?
melting
evaporation
condensation
somebody collects it
7
The top layer of the leaf is called the ...
spongy layer
cuticle
palisade layer
epidermis cells
8
What is the process called that plants loose water from their leaves?
respiration
photosynthesis
transpiration
translocation
9
The stomata are found
on top of leaf
on bottom (underside) of leaf
10
The stomata will close
when there is enough light
when there is not enough light
11
What piece of equipment measures the rate of transpiration?
potodriver
potometer
plant leaves
12
what is this?
palisade cell
muscle cell
animal cell
root hair cell
13
Which factor is
not
a limiting factor of photosynthesis?
carbon dioxide concentration
light intensity
oxygen concentration
temperature
14
Gas exchange occurs in the...
palisade
guard cells
spongy layer
epidermis
15
Why are leaves thin?
because it makes them look nice
so water can pass from one side to another
so gases can exchange quickly
16
What is glucose in the plant used for?
making new plant molecules (growth)
respiration
eating
sending messages
17
Why would a dry environment, like the desert, increase the rate of transpiration
there is little water in the air- the water is lost quicker.
there is lots of water in the air,so water wants to join it.
the plant doesn't need water
