Mode of feeding in free living protozoan is
1 holozoic
2 saprozoic
3 both [a] and [b]
4 none of these
Explanation:
The mode of feeding in free living protozoa is both holozoic and saprozoic. The intake of the complex substance, then breaking them down in simpler forms and gradually absorbing nutrition from it, is called holozoic nutrition whereas, the intake of simpler substances and absorbing nutrition from it, is called as saprozoic nutrition.

Which is correct?
1 Pellicle is absent in Euglena
2 Slime moulds are haploid
3 Protozoan lack cell wall
4 Dinoflagellates are immotile
Explanation:
The Protozonas lack cell wall. They are unicellular organisms found in freshwater and marine water. The slime moulds are diploid whereas dinoflagellates are motile. Pellicle is present in Euglena.

Pseudopodia are produced by
1 Plasma cell
2 Mast cell
3 Adipose cell
4 Fibroblast cell
Explanation:
The pseudopodia are produced by fibroblast. They are the cells of the connective tissue. They produce the fibres like collagen and the extracellular matrix.

During conjugation in Paramecium
1 Out of the four micronuclei formed, three nuclei degenerate
2 Out of six macronuclei formed, four nuclei degenerate
3 Zygote nucleus undergoes eight successive division in each conjugates
4 Out of 16 nuclei, only four degenerate
Explanation:
In Paramecium, during conjugation, the micronucleus undergoes two successive divisions one of which is meiosis. The four haploid daughter nuclei are formed out of them three degenerate and one divides from them, to form two gametic nuclei, one male and one female.
