Which one among the following statements is not correct?
Updated On: Jun 21, 2022
- Contractile vacuoles perform osmo reguation in marine protozoans.
- Euglena shows holophytic nutrition.
- Trypanosoma belongs to the Class Mastigophora
- Class Sporozoa includes Plasmodium.
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Contractile vacuole is found in all fresh water protozoans. Contractile vacuoles take part in osmoregulation and excretion. Osmoregulation is required in fresh water habitat where water has tendency to enter the living cells.

Biological Classification
The process of grouping living organisms into categories is called biological classification. The most modern 5-kingdom classification was put ahead by an eminent scientist R.H.Whittaker. The five-kingdom classification is based on the criteria like cell structure, mode of nutrition, body form, and reproduction. One of the most important characteristics of this system is that it follows the evolutionary sequence of living organisms. The organisms are classified into distinct taxa or levels like Kingdom, Phylum, Division, Class, Order, Family, Genus, and Species. The 5 kingdoms are as follows:
