The following points highlight the three main types of locomotion exhibited by protozoans. The types of locomotion are: 1. Amoeboid Movement 2. Flagellar Movement 3. Ciliary Movement. Protozoans: Type of Locomotion # 1. Amoeboid Movement: In Amoeba, movement of the animal is made by the throwing of pseudopodium (Fig. 10.60), called amoeboid movement. This is the most primitive kind of [...]
The following points highlight the three main classes of Phylum Porifera. The three classes are: 1. Calcarea or Calcispongiae— (Calcareous Sponges) 2. Hexactinellida or Triaxonida or Hyalospongiae—(Glass Sponge) 3. Demospongiae. Phylum Porifera: Class # 1. Calcarea or Calcispongiae— (Calcareous Sponges): [Calcarea, L. Calcarious = limy, Calcispongiae, L. Calcis = genitive of calx = lime or chalk] Features: (i) Exclusively marine, [...]
