Cell Growth & Division
As a cell increases in size, its ratio of surface area to volume _________________.
As a cell’s size increases, it places more demands on its ___________.
The ____________ the cell is, the more difficult it is for the cell to move enough materials across its cell
membrane.
Cell Division solves the problem of cell growth by _____________ cell volume.
Typically, the longest phase of mitosis is ________________.
A cell splits into two daughter cells during ________________.
Normal cells _______________ ____________________ when they come in contact with other cells.
As a cell becomes larger, its ______increases faster than its _______
______.
As a cell grows, it uses up __________________ & ______________ more quickly & has trouble moving
enough materials across its cell membrane.
Cell growth can cause problems for cells such as: ______ overload, obtaining enough ______________, &
expelling _________.
Compared to small cells, large cells have more trouble moving needed _____________ in and
______________ products out.
The process by which a cell divides into two daughter cells is called _____________ _______________.
