They aren't, the palacaid layer, the spongy layer and guard cells all contain chloroplasts.

On which layer of epidermis are guard cells found?

Guard cells are found on the epidermis of plant leaves, specifically within the lower epidermis. These specialized cells control the opening and closing of stomata to regulate gas exchange and water loss in the plant.


Why the epidermal cells do not have chloroplasts?

Chloroplasts are necessary for photosynthesis. This must in some way be necessary to operate the opening and closing of stoma. The neighboring epidermal cells do not have chloroplasts and do not require large amounts of energy from photosynthesis do to their simple job of being the "skin" of the leaf. These epidermal cells are fed by lower layers which do have chloroplasts.


Which type of dermal cell has more chloroplasts than any other dermal cells because it has greater energy needs?

Guard cells have more chloroplasts than any other dermal cells because they need energy to facilitate the opening and closing of stomata for gas exchange and water regulation in plants.


The cells that make up the epidermis are both living and?

The cells that make up the epidermis are both living and dead. The top layer of the epidermis, known as the stratum corneum, is made up of dead cells called corneocytes. However, the lower layers of the epidermis contain living cells that are actively dividing and producing new skin cells.


Like your skin a leafs what protects its more tender inner cells?

tissues are layers of similar cells. the outside layer of a leaf is called the epidermis tissue. the epidermis is made of flat cells . this layer is like the top layer of your skin. it protects the plant.

How many kinds of cells does the lower epidermis have?

The lower epidermis typically consists of a single layer of cells, mainly containing guard cells, subsidiary cells, and stomata. Guard cells control the opening and closing of stomata to regulate gas exchange and water loss in the leaf. Subsidiary cells provide support to the guard cells in carrying out their function.

Why lower epidermis has more guard cells?

The lower epidermis of a leaf typically has more guard cells because it is exposed to the external environment and plays a crucial role in regulating gas exchange and water loss through stomata. Having more guard cells allows for a higher density of stomata, which helps optimize the balance between gas exchange for photosynthesis and water conservation.


What will an epidermis cell look like?

If it is a upper epidermal cell then it will looktransparentclose fittingrectangulara horizontal shapeThe upper epidermal cells are transparent and close fitting, containing no chloroplasts, which are present in other leaf cells. They allow light to pass straight through them. The epidermis is covered by a waterproof cuticle, which reduces water loss from the leaf, since it is a waxy substance.If it is a lower epidermis cell then it will look like cells covered in tiny pores (holes)The lower epidermis has tiny pores (holes)in it's surface called stomata.These are very important for the leaf to exchange gases with the air. The stomata pores can be opened or closed by special cells on either side of the pore called guard cells. thes sausage shaped ceel are green and are thae only epidermal cells to contain chloroplasts

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.


Where are mesophyll cells located?

Below the upper epidermis and above the lower epidermis.


Which has more stomata the upper or lower epidermis?

Typically, the lower epidermis has more stomata compared to the upper epidermis. This arrangement helps plants regulate gas exchange, such as carbon dioxide intake and oxygen release, more efficiently.


How many layers does the epidermis have in hair?

how many layer of cells make up upper epidermis and lower epidermis


Where does photosynthesis usually occur in epidermis?

The epidermis of most plants is made of transparent cells that allow light into the mesophyll cells below them, which contain chloroplasts and are the site of photosynthesis. Additionally, the epidermis contains stomata, which are pores that allow for the exchange of gases with the atmosphere. This lets the plants take in carbon dioxide and release oxygen, as well as allowing for transpiration (evaporation), which ultimately helps to move water into leaves. Waters is also needed for photosynthesis.


Are the outermost cells of the epidermis living or dead?

Cells in the lower layers of the epidermis divide continually, producing new cells that constantly push through the layers of the epidermis. By the time those cells reach the outer layer of the epidermis, they are dead and ready to slough off.
