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?
