Diffusion does not occur through the upper epidermis primarily because it is covered by a waxy cuticle, which acts as a barrier to water loss and prevents the passage of gases and substances. Additionally, the upper epidermis consists of tightly packed cells that lack intercellular spaces, further restricting the movement of molecules. This adaptation helps protect the plant from desiccation and pathogen entry, ensuring that gas exchange primarily occurs through specialized structures like stomata located in the lower epidermis.

What passes through the upper epidermis of a leaf?
The upper epidermis of a leaf is primarily permeable to light and gases. It allows sunlight to penetrate for photosynthesis while also facilitating the exchange of gases, such as carbon dioxide and oxygen, through structures called stomata. Additionally, water vapor can exit the leaf through the upper epidermis during transpiration. The epidermis also serves as a protective barrier against environmental stresses.
Is The lower epidermis covered with cuticle?
No, the upper epidermis is covered by a cuticle.
What is the function of the plant upper epidermis?
The upper epidermis is responsible for preventing water loss by evaporation. It does this by having a waxy cuticle on the top of the leaf. The lower epidermis has stomata, which allow gases to enter and leave the leaf as a result of photosynthesis and respiration.
Is upper epidermis specialized for photosynthesis?
No, the upper epidermis of a leaf is not specialized for photosynthesis. Its main function is to protect the underlying mesophyll tissue and help reduce water loss through the leaf surface. Photosynthesis primarily occurs in the mesophyll cells located below the upper epidermis.
Why do the lemna form their stomata in the upper epidermis?
Lemna, also known as duckweed, form their stomata in the upper epidermis to increase gas exchange efficiency. Placing stomata on the upper surface allows for easier access to carbon dioxide from the air for photosynthesis while minimizing water loss through transpiration. This adaptation helps lemna thrive in their aquatic environment.
Why is the upper epidermis clear?
Upper epidermis is clear so that light can pass through and reach the palisade which are located below
What is upper epidermis?
upper epidermis is sadsadsa
Which is more advantageous to plants-more stomata on the upper epidermis or lower epidermis?
upper epidermis for sure>>>

What is the upper epidermis used for?

What is the medical term meaning surface layer of the skin?

Why is the upper epidermis thicker than the lower epidermis?
the epidermis is thicker.
How many layer thick is the epidermis?
Answer: the epidermis of a leaf includes: upper epidermis and lower epidermis but if you are referring to the epidermis of an onion: it is only one layer
Is The lower epidermis covered with cuticle?
No, the upper epidermis is covered by a cuticle.
Where are mesophyll cells located?
Below the upper epidermis and above the lower epidermis.
What do lower epidermis do?
protects against water loss the same as the upper epidermis do
How many layers does the epidermis have in hair?
how many layer of cells make up upper epidermis and lower epidermis
