What is the main function of the spongy layer of a leaf?
The spongy layer of a leaf, which lies beneath the palisade layer, consists of cells that are irregular in shape and loosely packed. Their main function seems to be the temporary storage of the sugars and amino acids that were synthesized in the palisade layer. The spongy layer also aids in the exchange of gases between the leaf and the environment.
Why calculate leaf surface area with transpiration?
The stomata on the underside of the leaf regulate transpiration. The leaf surface area helps to estimate the number of stomata, which could speed up or slow the rate of transpiration.
How does light affect the gradient of water potential of a plant leaf?
Transpiration regulates how much water moves through the plant. In hot dry air, more water will evaporate out of the stomates resulting in a higher transpiration rate. Light, or temperature, can therefore increase transpiration. Wind will evaporate more water from the leaf's boundary layer resulting in a higher transpiration rate. Humidity or moisture will lower transpiration because less water will evaporate out of the stomates.
Evaporation of water from surface of the leaf is called?
This phenomenon is called transpiration.
Why is the waxy cuticle on a leaf?
The wax cuticle covers the upper epidermis. The main task of the cuticle is to activate cuticular transpiration in a plant. Sometimes a very shiny cuticle may be present in a plant to minimize transpiration of the plant. It basically reflects back sunlight. These are the two main functions.
What is given out by the leaf?
Water is released by the leaf through transpiration.
Describe the differences in the shapes of the kinds of leaf cells that make food?
There are clear differences in the shapes of the kinds of leaf cells that make food. Some of them have a spongy layer while other will have a palisade layer. This will determine various processes like photosynthesis and transpiration.
What does the spongy layer of a privet leaf do?
Spongy Layer - A layer of the mesophyll. The spongy layer consists of chloroplasts and parenchyma cells, and relatively large intercellular spaces. It is far less ordered than the palisade layer, and the intercellular spaces are important in gas exchange and transpiration.
Why the stomata on undersurface of leaf?
To minimize the rate of transpiration from leaf surface
Compare the rate of transpiration from two surfaces of leaf and give reasons?
Compare the rate of transpiration from two surfaces of leaf and give reasons?"
What is the prosses in which water vapor escapes the leaf?
Transpiration
When water evaporates from a leaf what is that called?
transpiration
