Question

the mass change in the cell above is due to which of the following processes? (sc 912 l 14 2)
a. osmosis
b. active transport
c. diffusion
d. endocytosis

Explanation:

Osmosis is the movement of water molecules across a semi - permeable membrane from an area of higher water potential to an area of lower water potential. A change in cell mass can occur due to osmosis as water enters or leaves the cell. Active transport requires energy and is for moving substances against a concentration gradient. Diffusion is the movement of substances other than water (e.g., gases, small molecules) from high to low concentration. Endocytosis is the process of a cell engulfing substances. Since the question is about mass change in a cell likely due to water movement, osmosis is the most appropriate answer.

Answer:

A. Osmosis
