Charlotte wants to model a cell process she is learning about. She has two raisins, each measuring 3 mm in width. She places one raisin in a glass of fresh water and one raisin in a glass of salt water. After five minutes, she measures the width of each raisin and records her data in a table.

Question

Based on the data in the table, select the answer to complete the sentence.

This model demonstrates _____ because ______ moves into or out of the raisin.

a. endocytosis; water

b. osmosis; sugar

c. active transport; salt

d. osmosis; water

Answer 1

The correct answer is:

d. osmosis; water

Osmosis is the process through which water moves across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. In this case, the raisin in fresh water would absorb water, while the one in salt water would lose water due to the higher concentration of salt outside the raisin.
