If the cell is large the substances can not get into and out of the cell fast enough to deliver the things the cell needs to live.
The small unit would be cells
Not as small as your penis
why can small cells exchange substances more readily than large cells?
With smaller cells, there is a greater surface area.
expressed in the stomach, but not in the cells of the small intestine castlelearning. lol
1. surface area 2. volume
Animal cells have small vacuoles, whereas plant cells have large vacuoles.
very small
why can small cells exchange substances more readily than large cells?
No, all multicellular organisms have the same size cells.
small cells have a greater surface-to-volume ratio than larger cells.
it is mostly good for warming sanitary water or you can get electricity from it, but it has quite small efficiency, so i prefer solar systems then cells. We must consider energy used for cells... production.
I just learned about this in school. They need to be small in the ratio to make them more efficent in having molecules enter and leave them quickley.
existing
yes they are small and they have no nucleus unlike eukaryotic cells that do have a nucleus and are large.
There are trillions of cells in the body so, they have to be extremely small to fit.
Columnar epithelial cells.
