(a) Protista has appendages like cilia and flagella for locomotion and gathering food. 

(b) ‘Angio’ means covered and ‘sperma’ means seed. This group is usually referred to as angiosperms because, as their name implies, their seeds are enclosed in a carpel (in a vessel). The carpel is the primary feature that distinguishes angiosperms from gymnosperms. 

(c) Firstly, it acts as a protective layer so that harmful objects, fungus, bacteria and parasites cannot enter the fish body Secondly, they are present in overlapping pattern and only small part of scale is visible which makes the fish body smooth but itself the scales are hard. Scales allows the fish to move easily in vertical and horizontal direction in water Thirdly, it protects their bodies from rotting in water.
