What is the surface area of a cell? A. the amount of DNA contained inside the cell
B. the amount of waste leaving the cell
C. the amount of workable space that the cell has
available for exchange
D. how many nutrients are needed in the cell

C.

Explanation:

Here, surface area is the area of the outside of the cell, called the plasma membrane. The volume is how much space is inside the cell. The ratio is the surface area divided by the volume. This indicates how much surface area is available compared to how big the cell is.

C. the amount of workable space that the cell has available for exchange.

Explanation:

The surface area of a cell is its plasma membrane, and it is where nutrients and wastes are exchanged.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
