why do cells divide

they want to stay small because they function better

what is the largest single celled organism

giant amiba

cellular communication is more effective in a

smaller cell

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

L*W*#of sides

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

interphase: chromosomes tighten, cell growsmitosis: 4 parts, divides it nucleuscytokinesis: 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
