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.
Why removing the lower epidermis layer of the leaf and not the upper epidermis?
Removing the lower epidermis layer allows for easier observation of stomata and overall leaf structure. Stomata are mostly located on the lower epidermis, which regulates gas exchange for photosynthesis. Additionally, removing the upper epidermis may damage the leaf's cuticle, which can affect its ability to retain water.
Why dicot leaf is known as dorsiventral leaf?
Dicot leaf is also called dorsiventral leaf as it has both dorsal and ventral side with identifiable features. The protective layer is named as Epidermis and there is both upper and lower epidermis. In dorsiventral leafs the lower epidermis which is also called abaxial side will have more number of stomata compared to the adaxial side or upper epidermis. The gap between the two epidermis is termed as mesophyll and in dicot leaf we can see a differentiated mesophyll region. The region is differentiated into palisade and spongy tissue. The region just below upper epidermis have elongated parenchyma cells with chlorophyll filled in and they are called Palisade tissues. This is the main reason behind dark green colour at upper side of a dicot leaf.
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.
What is a palisade layer job in a leaf?
The palisade layer is responsible for photosynthesis in the leaf. It contains chloroplasts that capture sunlight and convert it into energy through the process of photosynthesis. The palisade layer is located beneath the upper epidermis and is where the majority of photosynthesis occurs in a leaf.
What best describes a leaf's epidermis?
The epidermis covers the lower and upper sides of the leaf.
What will happen if you only apply vaseline on the upper epidermis of a leaf?
The leaf would curve to the upper epidermis exposing the lower epidemis
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
What does upper epidermis mean?
The upperside of a leaf
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.
Where in the lieaf are most chloroplsts are found?
In a leaf,a most of the chloroplasts are found in the upper epidermis layer. A leaf has four distinct tissue layers, upper epidermis, lower epidermis, spongy layer, and palisade layer.
Which is the portion of the leaf between the upper and lower epidermis called?
mesopyll
Why removing the lower epidermis layer of the leaf and not the upper epidermis?
Removing the lower epidermis layer allows for easier observation of stomata and overall leaf structure. Stomata are mostly located on the lower epidermis, which regulates gas exchange for photosynthesis.

Where in a leaf would you expect to find palisade cells?
Palisade cells are typically found in the upper layer of a leaf called the palisade mesophyll. They are located directly beneath the upper epidermis and are responsible for carrying out photosynthesis due to their high concentration of chloroplasts.
How do you draw and label each part of leaf?
Can't draw a diagram for you but, from top to bottom: cuticle-waxy substance secreted by epidermis cells that waterproofs the leaf upper epidermis-closely fitted together like a jigsaw. no chlorophyll palisade layer-where most photosynthesis occurs. chlorophyll present spongy layer-gases diffuse through this layer. chlorophyll present lower epidermis (contains stomata)-like upper epidermis. stomata contain chlorophyll
What is the epidermis in a leaf?
The surface of the leaf that you see is the "epidermis".
