What two cells make a What are the names of the two
cells that make up a stoma
singular for stomata? and in
what way might the cutin
affect the efficiency of
photosynthesis?
|
|
 |
|
|
 |
1) The Stoma are created by two Guard Cells. 2) Cutin is a waxy substance on leaves and could reduce the amount of light available and thus hinder photosynthesis (one hypothesis). Or it could reduce the amount of gaseous exchange through the leaves. |

When a leaf is coated with I know that coating a leaf
with petroleum jelly reduces
evaporation through from the
surface of the leaf, but can
water vapor still be lost
through its stoma?
|
|
|
|
|
|
when petroleum jelly is coated on a leaf surface,it blocks the stomata completely and conserves water and reduces rate of transpiration.so no loss of water vapour. |

What is the purpose of a In between the guard cells,
where the stoma is formed,
there is a thick wall. The
wall is designed to be thick
for a reason.
Can anyone please tell me what
that reason is?
Thank you!

ok if you remember biology the reason it is so thick is so water does not evaporate out of the cells but only thru the stoma. and it helps in keeping the plants rigid also with the help of turgur pressure which is basically water under pressure in the cell. |
