ANSWERS

Amoeba

Paramecium

Paramecium is a unicellular organism which lives in fresh water habitats such as lakes, ponds, streams, rivers and puddles.These tiny microscopic creatures has transparent body wall called Pellicle covered with several tiny hair like structures called Cilia. Several cilia produce lashing movements and enable paramecium to move in water. It feeds on bacteria, algae and other protists. It has a opening for feeding called Cytostome or oral groove, through which it takes its food by ciliary movements. The flower like stuff which you see in the top and bottom are Contractile vacuoles, they excrete excess salts to out side. It reproduces asexually  by Binary fission where the Paramecium literally splits its body vertically into two daughter paramecia. It is also known as Slipper animalcule because of its typical slipper shape

Euglena is unicellular creature which lives in Ponds. It is known for its dual modes of nutrition. Euglena can prepare its own food by photosynthesis like Plants and even can feed on algae and bacteria. It has a long whip like Flagellum by which it swims in water. This organism responds to light through a photosensitive Eyespot.It reproduces asexually by longitudinal fission.
