Transpiration is the loss of water vapour from the plant from the stomata of the leaves..

the answer is C because it is asking for the ratio of the phenotype and genotype i.e how many pairs of offspring have the same phenotype and how many pairs of offspring have the same phenotype.

Humidity : alot of humidity makes transpiration slow
Light: more light more transpiration
Temperature : high temp means more transpiratoins
Area: larger area means more transpiration

It is the process inside the leaf inwhich glucose is changed to sucrose and transported to all parts of the plant (from the leaf) through the phloem!
