Q2 of 16 Page 72

In order to observe protozoa like amoeba and paramecium, collect the petals of some flowers. Place them in water for a day or two. Observe a drop of this water under a microscope.

You will observe Amoeba and Paramecium are single celled. Like most plant and animal cells, it has cytoplasm,

Nucleus, cell membrane and cell organelles in the cytoplasm, contractile vacuoles.


They exhibit all the essential functions of any living organism.


Amoeba has projections of varying lengths protruding out of its body.


These are called pseudopodia (pseudo: false; podia: feet). These projections appear and disappear as Amoeba moves or feeds.


Unlike amoeba, paramecium has a particular permanent slipper shape and certain areas of cytoplasm, (Cell organelles) carry out specific functions. Cilia are present all over the body surface for movement.
