How does:
i) the thickness of cuticle
ii) the distribution of stomata
iii) the size of the leaf
influence the amount of light and the amount of CO2 entering the leaf?
Please mention whether they are directly or inversely proportional to the factors mentioned above.

Dear student,
i) the thickness of cuticle is inversely proportional to the influence of light and carbon dioxide entering into the leaf.The cuticle is the waxy layer present on all above-ground tissue of a plant and serves as a barrier to water movement out of a leaf. so less light will enter and less transpiration will occur. In general, plants from hot, dry climates have thicker cuticles than plants from cool, moist climates. In addition, leaves that develop under direct sunlight will have much thicker cuticles than leaves that develop under shade conditions.

ii) the distribution of stomata is directly proportion to the influence of light and entrance of carbon dioxide. as more will be the stomata more will be the absorption of light and co2 . thus more will be the process of photosynthesis .

iii) the size of the leaf is also directly proportional the amount of light and carbon dioxide entering in the leaf. as more the surface area of leaf more will be number of stomata thus increasing tha absorption of both light an carbon dioxide.

  • The cuticle on this epidermis is unusually thick, almost one-half the thickness of the lumen of the cell.
  • Distribution of StomataDistribution of stomatavaries between monocots and dicots, between plant species, and between the underside and top side of the leaves on a plant. ... Usually the lower surface of a dicot leaf has a greater number of stomata while in a monocot leaf they are more or less equal on both surfaces.​​
  • Most were the dimension on that Raunkiaer classification, Ms, or mesophyll. An Ms-B leaf is 5 cm (2 inches) to 7 cm (2.75 inches) wide. There is something important to leaf size and shape.
