How is the spongy mesophyll adapted for gas exchange?
It is close to the palisade cells
It contains chloroplasts
It has air spaces and a large surface area
It contains lots of small cells
Where in a leaf does photosynthesis occur?
In chloroplasts
In palisade cells
In spongy mesophyll cells
All of the above
Why are palisade cells arranged at the top of the leaf?
So that they are far away from the stomata
So that sugars made on photosynthesis can be transported to the phloem
So that chloroplasts are concentrated in one place
So that chloroplasts receive the maximum amount of sunlight
What is the name of the clear layer of cells (H) on top of the leaf?
Cuticle
Air space
Guard cell
Upper epidermis
What is the name of cells (part D) that surround the pores of a leaf?
Palisade cells
Guard cell
Spongy layer
Lower epidermis
If guard cells are swollen with water, then they are more likely to be ...
OPEN with stomata
CLOSED with no stomata
Cannot tell - the water amount doesn't affect it at all.
