Does the size of a leaf affect the rate of transpiration?

Answer 1

The more leaves the plant has, the more surface there is for photosynthesis. This means there will be more stomata so the plant can take in more carbon dioxide. This will also result in more water vapour leaving the plant.

Answer 2

Leaves that are big-sized are capable of increasing the rate of transpiration if there is great sun illumination. This is why the plants in dry areas should ideally have small and needle-like leaves.

Answer 3

Think of this as a question about how the leaves gather light.

Leaf color: greener leaves have more chlorophyll to trap the light.

Leaf shape: leaf blades are often broad and flat to have maximum exposure to the light. Compare this with the needles of a pine tree which don't allow as much light to hit them.

Leaf size: larger leaves have more surface area to be exposed to the light. Often plants that live in the shade have large leaves in order to get enough light.

Leaf position: think of a tree that has leaves on the outer parts of the branches and other leaves that are more within the crown of the tree. Leaves exposed to direct, unfiltered sunlight on the outside of the plant will be able to photosynthesize more than the leaves on the inside that get filtered light.

Answer 4

Yes, simply put the size of a leaf effects the temperature of a leaf and the temperature of the leaf effects the transpiration rate of the leaf; so leaf size has an indirect but substantial effect on the rate of transpiration.

Answer 5

If the surface area of the leaf was quite big then the rate of transpiration would increase. This is because some water is lost through the cuticle of the leaf. Therefore the bigger the surface area of the leaf, the higher the rate of transpiration! :)

Answer 6

Yes, the size of a leaf can affect the rate of transpiration. Larger leaves generally have a larger surface area for water loss through stomata, which can lead to higher transpiration rates compared to smaller leaves. Additionally, larger leaves may have more stomata, increasing the potential for water loss.

Answer 7

Larger the size of the leaf has greater surface area for receiving the sunlight and more stomata will have higher rate of transpiration, if other factors remain normal.

Answer 8

Light affects transpiration because plants transpire faster in the light than in the dark. This is mostly because light stimulates the opening of the stomata.

Answer 9

Transpiration rate depends on leaf (surface area )more the surface area of leaf more the transpiration will occur.
