The uppermost layer of the packed cell column is formed by red blood cells, also known as erythrocytes. Red blood cells are the most abundant type of blood cell and are responsible for carrying oxygen from the lungs to the rest of the body. They are disc-shaped cells that lack a nucleus and contain hemoglobin, a protein that binds to oxygen.
What else can I help you with?
Why are the cells of the palisades layer packed so tightly togehter?
Packing palisade cells tightly together means that the maximum amount of light can be intercepted. If there are big gaps between the cells then more of the light hitting the leaf will just pass straight through.
What is the uppermost layer of the atmostphere?
In the case of bodies with substantial atmospheres, such as Earth's atmosphere, the exosphere is the uppermost layer, where the atmosphere thins out and merges with interplanetary space. It is located directly above the thermosphere.
Is the uppermost layer of skin full of keratin?
Yes, the uppermost layer of skin, called the epidermis, is full of keratin. Keratin is a tough protein that gives the skin its structure and helps protect it from external factors such as water loss and infection.
What structures are found in the palisade layer in the mesophyll?
Lying just beneath the cuticle layer on a leaf, the palisade layer resides very close to the surface. The palisade layer is critical to growth because it is the layer of the leaf that contains the chloroplast.
What is a large mass of closely packed leaf like bundles of nerves cells?
A large mass of closely packed leaf-like bundles of nerve cells is known as the cerebral cortex. This outer layer of the brain is responsible for higher brain functions such as thinking, planning, and processing sensory information.
What is the uppermost layer of skin consisting of flat keratin-filled cells?
The uppermost layer of skin is the the stratum corneum.
When the urinary bladder is distended with urine the epithelial cells in the uppermost layer are?
squamouslike
What are column like cells the lie just under the epidermis?
Palisade cells are the column like cells that lie just under the epidermis. Palisade layer is one layer of the mesophyll.
What is the uppermost layer of dirt?
The uppermost layer of dirt is typically called topsoil. It is the outermost layer of soil that is rich in organic matter and nutrients, making it ideal for plant growth.
The lower portion of the mesophyll usually consisting of loosely packed spherical cells?
spongy layer
The uppermost layer of skin that is sloughed?
blipe
Do The uppermost layer of the soil?
It is called 'topsoil'
What is the name of the uppermost layer of atmosphere?
exosphere
Why are cells of the palisades layer packed so tightly together?
Packing palisade cells tightly together means that the maximum amount of light can be intercepted. If there are big gaps between the cells then more of the light hitting the leaf will just pass straight through. Tightly packed palisade cells is one way in which leaves are adapted for photosynthesis.
The Uppermost atmospheric layer?
The uppermost atmospheric layer is the THERMOSPHERE. here temperature again increases with altitude because many of the gases are absorbing solar radiation.
Why are the cells of the palisades layer packed so tightly togehter?
Packing palisade cells tightly together means that the maximum amount of light can be intercepted. If there are big gaps between the cells then more of the light hitting the leaf will just pass straight through.
What is the uppermost layer of soil called?
The uppermost layer of soil is called topsoil. It is the layer that contains the highest concentration of organic matter and nutrients, making it crucial for plant growth.
