  1. a. captures prey
  2. b. stores food
  3. c. expels water
  4. d. detects light

Summary Introduction

Concept introduction: Protists are eukaryotes and the interior of some freshwater protists like the euglena is saltier than its freshwater habitat. Due to this, the water will tend to diffuse into the cell of protists. Excess of water will cause the cell to burst. However, the contractile vacuole present in the cell will help to maintain the water concentration in the cell.

Explanation of Solution

Reasons for the correct statement:

Contractile vacuoles are the organelles present in some protists such as euglena. It collects the excess water present in the cytoplasm, then contracts and expels out the excess water from the cell through a pore.

Option c. is given as “expels water”. As the contractile vacuole functions to expel the water from the organism option c. is correct.
