|
What name is given to the cells highlighted on the diagram above?
|
What name is given to the openings indicated on the diagram above?
|
opaque / transparent / smooth / palisade / mesophyll / guard
The upper epidermis is so that light can pass through it. This means that as much light as possible can reach the mesophyll cells below, and be used in photosynthesis.
|
Which structures help to minimise water loss?
(Select all that apply)
Lots of spongy mesophyll cells
Guard cells which can close stomata
Transparent upper epidermis
Waxy cuticle
|
flaccid / turgid / opens / closes / enter / leave
If there is plenty of water in the leaf, guard cells become , which the stomata. This allows carbon dioxide to the leaf, but also allows water to escape.
|
Most of the stomata are found on the ________ of the leaf.
bottom
top
|
At night time, when photosynthesis can't take place, are the stomata normally open or closed?
Open
Closed
|
What is meristem tissue and where is it found?
