Answers
1
State the name of the structure in which water transpires out of a leaf.
Mesophyll
Palisade
Guard Cells
Stomata
2
Explain why transpiration occurs.
The Sun evaporates water
Plant is thirsty and needs water
The roots draw up water
Due to dry conditions
3
Name "A"

Epidermis
4
Which water property/properties help pull water up the xylem?
Adhesion and cohesion
Density and adhesion
Cohesion and density
Density, adhesion, cohesion
5
State the nutrients required by plants.
Oxygen, organic nutrients, ions, water, urea
Carbon dioxide, oxygen, inorganic ions, water
Carbon dioxide, oxygen, organic nutrients, ions, water
Carbon dioxide, organic nutrients, organic ions, water
6
Describe why carbon dioxide and oxygen do not require a transport system to travel in plants.
They are processed in the plant leaves
Stomata
Active Transport
Diffusion
7
State the vessel responsible for the transport of water (and inorganic ions).

9
Define apoplastic pathway.
Water moves cell-to-cell through plasmodesmata.

12
State the role of the casparian strip.
Makes all water move via symplast pathway
Controls the amount of water going in the xylem
Makes all water move via apoplast pathway
Filters water and ions before going in the xylem
13
State the mechanism by which water enters root hair cells
Facilitated diffusion

Magic
Cell walls
18
Liquid water is found on the _______________ cells.
