The upper epidermis has several functions. It protects against water loss, regulates gas exchange (there are only a few stomata on the uppermost layer of the leaf) and produces the waxy substance that becomes part of the cuticle.
The previous answer to this question implies that leaves have a SPINAL CORD - note, this is not true!
What else can I help you with?
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.
The portion of the leaf between the upper and lower epidermis is called the?
The portion of the leaf between the upper and lower epidermis is called the mesophyll. It is where photosynthesis primarily takes place, with the palisade mesophyll located closer to the upper surface for maximum light absorption and the spongy mesophyll situated beneath for gas exchange.
Which part of the leaf can best ne compared be your skin?
The epidermis of a leaf can be compared to the outer layer of human skin. Just like skin, the epidermis acts as a protective barrier, regulates water loss, and helps prevent damage from external factors. Both the epidermis and skin play a crucial role in maintaining the health and function of their respective organisms.
What are cells between the upper and lower epidermis of the leaf called?
Mesophyll In between upper and lower epidermis of leaf is mesophyll tissue. In the dorsiventral leaves, mesophyll is divisible into upper palisade cells and lower spongy parenchyma. The palisade cells are mainly involved in photosynthesis and spongy parenchyma in gaseous exchange.
What is the outer layer of the leaf called and what are its functions?
The outer layer of a leaf is called the epidermis (from a Greek word meaning "over-skin"). Its function is to protect the insides of the leaf, which carry out the chemical reaction known as photosynthesis.
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.
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
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.
What is the function of the epidermis in a monocot stem?
The function of the epidermis in the stem is to protect the underlying tissues.
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. 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.
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.
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.
