cell size

As the cells become larger _____

The surface area: volume ratio decreases

How does the shape of the amoeba allow to become much larger than other single cell organisms

It’s shape shifting ability, allowing for it to constantly change it shape in size in order to capture the resources in food and needs

What is diffusion?

The movement of molecules from an area of high concentration to an area of low concentration down a concentration gradient

How does diffusion work in a cell?

Diffusion allows substances to move in and out of cells

Measuring the volume of a box=

A X B X C

Smaller cells are more efficient because ____

Materials can move in and out of them faster

cells must exchange ______

Materials like oxygen nutrients and waste with its environment

If a sale gets too large it ___

Divides or stop growing killing the cell

Formula for surface area=

L X W X 6 sides

Total surface area formula=

2( a X b) + 2(b X c) + 2(a X c)

Surface area: volume ratio =

Surface area:volume (divide both sides by volume to reduce)

Formula for volume=

L X w X h
