What else can I help you with?
Do all eukaryotic cells have cell walls?
No, only plant cells have cell walls! Animal cells have a cell membrane.
Bacteria that produce thick walls around themselves are called?
Bacteria that produce thick walls around themselves are called Gram-positive bacteria. These bacteria have a thick peptidoglycan layer in their cell wall that retains the purple stain in the Gram staining technique. This thick wall provides structural support and protection to the bacterial cell.
How many layers thick is a capillary?
Capillaries are only one cell layer thick, which allows for the exchange of nutrients and gases between the blood and tissues. This thin structure promotes efficient diffusion and transport across the capillary walls.
What is a bacterial genus that has waxy mycolic acid in the cell walls?
Mycobacterium is a bacterial genus that has waxy mycolic acid in the cell walls. This acid helps make the cell walls impermeable to many substances, contributing to the resistance of the bacterial cells.
What provide the greatest surface area for gas exchange?
Alveoli in the lungs provide the greatest surface area for gas exchange in the body. They are tiny air sacs that are surrounded by capillaries where oxygen and carbon dioxide are exchanged during respiration. The numerous alveoli increase the total surface area available for this gas exchange process.
How many cells thick are the walls of capillaries?
They walls are a single layer of squamous epithelial cells.
How many cells have cell walls?
plant cells have cell walls
Why do many desert homes have thick walls?
Thick walls moderate the temperature. The home remains cooler in summer and warmer in winter.
Do all eukaryotic cells have cell walls?
No, only plant cells have cell walls! Animal cells have a cell membrane.
Are alveoli cells?
Yes. Alveolus is composed of many cells that work for a common function, to take out carbon dioxide and oxygenate the blood.
How many cells thick is the wall of an alveolar sac?
ONE CELL THICK !
Is your body made of many different cells or cell walls?
many cells. cell walls are found in plants, where the need stability and support to stay upright.
Why do they often thick walls and small windows?
Homes in the desert often have thick walls and small windows to keep out the sand. If there are too many openings the sand can accumulate quite rapidly.
How many cells thick is leaflet?
1 - 2
How is Alveoli well adapted to diffusion?
The alveoli have very thin walls, which allow for rapid diffusion into the surrounding capillaries. There are also many alevoli in the lung, and that increases the surface area dramatically, allowing for more diffusion to occur
How are the alveoli designed to maximise the exchange of gases?
the paouch like air secs at the smallest lenchioles is called alveoli.the walls of alveoli are very thin and they are sorrounding thin blood capllaries .it is in alveoli exchange of gaseouse takes place there are so many alveoli in blood so they provides very larges surface srea for cxchanges of gaseouse
Which kingdoms organism have no cell walls?
Animal cells do not have cell walls. Many animal-like protists also lack cell walls.
