As cell diameter increases, surface area to volume ratio decreases
This is because cell diameter increasing means cell volume is increasing, so SA:V ratio is smaller, as volume increases at a larger rate than surface area, and you are dividing by a larger number
valid points include:
- occurs through the semipermeable membrane of cells
- the movement of water molecules from an area of high concentration to low concentration
- the diffusion of water down a concentration gradient
- water moves from the hypotonic environment to the hypertonic
- hypotonic- lower concentration of solute than another solution. higher concentration of solvent (water)
- hypertonic- higher concentration of solute
- no energy is required, it is a passive form of transport
valid points include:
surrounded by a double membrane
contains a dense nucleolus
contains DNA in the form of chromatin, wrapped around histone proteins
the nuclear membrane has pores that allow for the transport of genetic material through the cell
