In Amoeba who gave contraction hydraulic theory?
1 Schultze
2 Claude
3 Simpson
4 Swan
Explanation:
Earlier it was given by Schultze and detailed explanation was given by Rinaldi. It explains how sol moves in the direction of locomotion. According to this, actin and myosin type of proteins are present in rear portion of Amoeba. Phase proteins produce hydraulic pressure by contraction. This pressure is maximum in front, minimum in middle and medium in rear.

In Plasmodium which one of the following is not distinct ?
1 Mitochondria
2 Golgi body
3 Cilia
4 Nucleus
Explanation:
The Plasmodium does not possess cilia. Plasmodium is a large genus of parasite protozoa. This parasite has two hosts in its life cycle, a mosquito vector, and a vertebrate host. It has all the organelles like mitochondria, golgi body, and nucleus. However, it does not possess cilia.

Diatoms belong to which class?
1 Phaeophyceae
2 Bacillariophyceae
3 Chlorophyceae
4 Xanthophyceae
Explanation:
Diatoms are placed in Protista as they are unicellular and eukaryotic. Diatoms are formally classified as belonging to the division Chrysophyta, class Baciliariophyceae.

Why Amoeba has been kept in Protozoa?
1 Due to contractile vacuole
2 Because of nutrition being insectivorous
3 Cell wall
4 Unicellular body
Explanation:
Protozoa is a group of microscopic, and unicellular, eukaryotic animalcules without tissue and organs, having one or more nuclei. The contractile vacuole is for osmo-regulation. Amoeba is carnivorous and its mode of nutrition is holozoic i.e. it feed by phagocytosis.
