Surface Area

Front

What is the definition of surface area?

Back

The total area on the surface of an object.

Front

How does surface area affect nutrient absorption in cells?

Back

The absorption of nutrients is determined by the cell's surface area.

Front

What are microvilli and what is their function?

Back

Microvilli are tiny projections that extend off the cell to increase the surface area, serving to increase absorption.

Front

What happens to the surface area to volume ratio as a cell's size increases?

Back

As a cell’s size increases, its ratio of surface area to volume decreases.

Front

Which type of cell will make greater demands for DNA?

Back

Large cells make greater demands for DNA.

Front

Why is a high surface area to volume ratio important for cells?

Back

A high surface area to volume ratio allows for more efficient exchange of materials with the environment.

Front

What is the relationship between cell size and metabolic activity?

Back

Larger cells may have higher metabolic activity but face challenges due to lower surface area to volume ratios.

Front

How can surface area be increased in biological systems?

Back

Surface area can be increased through structures like folds, microvilli, and branching.

Front

What is the significance of surface area in the context of diffusion?

Back

Increased surface area enhances the rate of diffusion, allowing for quicker exchange of substances.

Front

How does surface area relate to heat loss in organisms?

Back

Organisms with a larger surface area relative to volume lose heat more quickly than those with a smaller surface area.
