Which of the following processes are involved in the reproduction ofprotists?
1 Binary fission and budding
2 Cell fusion and zygote formation
3 Spore formation and cyst formation
4 All of the above
Explanation:
(d) In protists, reproduction takes place by means of asexual and sexual methods. Asexual reproduction occurs through binary fission (e.g. Euglena), cyst formation (e.g., Entamoeba), budding; sporulation, etc. In sexual reproduction, fertilization occurs through syngamy and conjugation.

Which of the following is an example of amoeboid protozoans?
1 Trypanosoma
2 Gonyaulax
3 Paramecium
4 Entamoeba
Explanation:
(d) Amoeboid protozoans are organisms that live in fresh water, sea water or moist soil. They move and capture their prey. by putting out pseudopodia (e.g. Amoeba). Some of them such as Entamoeba are parasites.
