Which has the greater surface area one large cell or 27 smaller cells?
27 smaller cells would have a greater surface area than one large cell. This is because the total surface area of the smaller cells would be greater due to the additional surface area of the cell membranes around each individual cell.
Why do epithelial cells have a large surface area?
Because they're flat.
How have cells from the windpipe adapted to do their job?
they have a large surface area, a good blood supply close by, thin walls (often only 2 cells thick) and are moist. This all aids in effective gas exchange.
Do the round shape of blood cells give then extra surface area?
Yes, the round shape of blood cells (specifically red blood cells) allows for a larger surface area-to-volume ratio, which is important for efficient gas exchange. This shape helps oxygen and carbon dioxide diffuse more easily across the cell membrane.
What are the adaptions of a red blood cell and a root hair cell to make a large surface area?
Red blood cells have a biconcave shape, which increases their surface area relative to their volume, allowing for more efficient gas exchange of oxygen and carbon dioxide. Similarly, root hair cells possess long, thin extensions that increase the surface area available for water and nutrient absorption from the soil. These adaptations enhance their respective functions by maximizing contact with their environments.
What features of the alveoli mean that gas exchange is more efficient?
They Have A large surface area and they are full of red blood cells
How do red blood cells adapt to their functions?
red blood cells adapt to their functions by squeezing through tubes and have a large surface area too. :) They have a flexible shape, which allows them to squeeze through narrow capillaries They have no nucleus, to allow lots of room for haemoglobin (which reacts reversibly with oxygen and carries it to all the cells of the body) They have a large surface area.

Why do red blood cells need a hole in them?
more surface area to absorb oxygen
Why does a red blood cell have a large surface area?
To hold more oxygen.

What has a large surface area to help the cells absorb water quickly?
Root hair cell
Why can small cells exchange substances more readily than large cells?
Small cells have a higher surface area to volume ratio, which allows for a more efficient exchange of substances with their environment. This is because the surface area of a cell determines the rate at which substances can be exchanged, and smaller cells have a greater surface area relative to their volume compared to larger cells.
Why are red blood cells concave?
Red blood cells are concave to increase their surface area, allowing for more efficient uptake and release of oxygen and carbon dioxide. This shape also gives the cells flexibility to squeeze through narrow blood vessels without rupturing.
