why do cells divide
they want to stay small because they function better
what is the largest single celled organism
cellular communication is more effective in a
the larger a cell becomes:
the more demand the cell places on its DNA
the smaller the cell:
the more effective it is
what is the equation for surface area
what is the equation for volume
what is the ratio about when it comes to size of cells
surface area : volume
about the ratio of surface area to volume: what increases faster?
volume increases faster than surface area
what happens to the ratio as the cell grows?
decreases making it very difficult to transport nutrients in and waste out
what are the 3 parts of the cell cycle? what happens in each
: chromosomes tighten, cell grows
: 4 parts, divides it nucleus
: divides cytoplasm
as organisms grow and develop,
the size of the cells don't change, just the quanity
when do daughter cells form
when one cell divides into two
how many chromosomes do human cells have?
what are somatic cells
cells in your body that don't include reproductive cells
how many chromosomes in reproductive cells
what are chromosomes made out of?
DNA and protein
when are chromosomes visible?
during cell division/mitosis
when does a cell copy its chromosomes?
where does a cell spend most of its life? and how long
