A human cell is normally 0.1 mm in the size. Human cells cannot be seen by the naked eyes without the help of magnification.
no, if that were true we would all still be a single cell
True
True
The side are always the same size and length.
true
E.Electrons move away from the anode.
Yes, but it is not always true.
A cell is small because small is a lot! Cells are not always the same size. Cell sizes vary for different cell types in the same species. A chicken egg that we eat is a cell.
No. Its size is limited by the cell's surface area to volume ratio. If the volume increases quicker than the surface area, the cell cannot release waste or take in nutrients as effectively. Also, the cell's DNA would not be able to keep up with the cell's functions.
There are two differences which are always true. Animal cells do not have a cell wall or a permanent vacuole, plant cells do.
becuase small is a lot...! it is not always the same size (in micrometers), the size varies from different cell types in the same species (human; sperm cells & neuron are longer!). Meantime, egg what we eat is also a cell! trust me!
the negative terminal of the voltage source is attached to cathrode.
