Question

~~9. Using the appropriate osmotic terms (hypertonic, hypotonic, or isotonic) describe what would happen to each organism in the following settings: on. A single-celled freshwater protist is placed into a beaker of salt water. (3 points) b. A salt-water snail is mistakenly put into a freshwater tank. (3 points) c. A head of lettuce is placed soaked in a sink of salt water. (3 points) d. A bunch of carrots are placed soaked a sink of distilled water. (3 points)

Answer 1

A single-celled freshwater protist in hypertonic salt water would shrivel; a salt-water snail in hypotonic freshwater would swell; lettuce in hypertonic salt water would become limp; and carrots in hypotonic distilled water would become crisp.

Step-by-step explanation:

Using the terms hypertonic, hypotonic, and isotonic to describe the osmotic effects on organisms in different environments:

• a. A single-celled freshwater protist in salt water: The salt water is hypertonic compared to the protist's cytoplasm. Water would move out of the protist, potentially causing it to shrivel and die.
• b. A salt-water snail in freshwater: The freshwater is hypotonic relative to the snail's body fluids. Water would rush into the snail, which may result in swelling or bursting of its cells.
• c. A head of lettuce in salt water: The salt water is hypertonic. The lettuce cells would lose water and the lettuce would become limp due to dehydration.
• d. A bunch of carrots in distilled water: The distilled water is hypotonic to the carrot cells. Water would enter the cells, and the carrots would become firm and crisp.
