1
What is translocation?
The movement of dissolved sugars through a plant
The movement of oxygen through a plant
The movement of water through a plant
The movement of carbon dioxide through a plant
2
What is the function of stomata?
Excreting gas
Gas exchange
Gas exchange and water loss
Water loss
3
What does the meristem tissue do?
Creat new cells for the growth of the plants.
Control gass exchange
produce nectars and auxins.
Retains water loss
4
How does water get to the palisade mesophyl?
Through the xylem
Through the roots
Through the phloem
Through the sun
5
Palisade cells are found in the roots of plants
True
False
6
The function of phloem tissue in a plant is to:
Protect the cell walls
Allow Osmosis to take place
True
Carry water and mineral ions from the roots
7
Where in the plant do you find meristem tissue
All over the plant
On the surface of leaves only
On root and shoot tips
Inside the pollen grains
8
Tissue is made of what?
organ systems performing a particular function
different cells working together o carry out a particular function
rubber
Similar cells working together to carry out a particular function
9

11
True or false: Plant cells do not contain mitochondria.
False
True
12
What is transpiration?
the loss of water from leaves
how plants get their color
None of the above
the female reproductive structure of a flower
13
The function of xylem tissue in a plant is to:
Carry water and mineral ions from the roots
Protect the cell walls
Allow Osmosis to take place
Carry sugars around the plant
14
What does the Epidermal tissue cover ?
Whole plant
Vessels

The roots only
15
Transpiration
doesn't
require:

16
The vascular tissue that has one-way movement in a plant is called the
lignin
phloem
companion cells
xylem
17
What is the function of the palisade cell?
To 'eat' bacteria
To carry genetic material
To carry out photosynthesis
To collect water and nutrients
18
The stomata are...
waxy layer on top of the leaf
cells that guard the gaps
tiny gaps in the epidermis of the leaf
the stem of the plant
19
Why do palisade cells contain many chloroplasts?
To increase the surface area
To absorb all the available light
Because the plant contains lots of chlorophyll
To make the plant greener
20

Vascular Bundle
Cuticle
Stomata
Mesophyll
