using what have you learnt about the effect of concentration gradient and surface area to volume ratio, explain the adaptations of a leaf for photosynthesis ​

Leaves have an increased surface area in order to increase light-harvesting and they are thin in order to increase the diffusion rate

Explanation:

Leaves have several adaptations to increase the photosynthesis rate. In the first place, leaves have a large surface area to increase light-harvesting and thus also increase photosynthetic energy conversion. Moreover, leaves are sufficiently thin to increase the gas exchange surface area, i.e., the entry of carbon dioxide (CO2) and the exit of oxygen from photosynthesis, which move by diffusion through stomata.

im not intirely sure but i think the anwser is d relative humidity

it is because according to the process , scientific inquiry is a process with many steps because each step occurs to the scientist and if you just skip a step there would be no steps to scientific inquiry.
