(e) Which organism is multicellular and which one is unicellular?

There are four tiny organisms A, B, C and D. organism A is a parasitic protozoan that causes a disease known as kala-azar. The organism B is a microscopic single-celled animal that causes malaria disease in human beings. The organism C is a unicellular animal that can change its body shape according to need, it has no fixed shape. The organism D is also a unicellular animal that is slipper-shaped having a large number of tiny hair all around its body.

(b) Name one characteristic body feature of organism A.
(c) Name the insect which carries organism B and transmits it from one person to another.
(d) What name is given to the asexual method of reproduction of (i) organism A, and (ii) organism B?
(e) Where do organisms C and D live?

An organism X having breathing organs A lives on land. When organism X goes under water, it cannot survive for a long time unless carrying an oxygen cylinder. On the other hand, the organism Y having breathing organs B always lives in water and if taken out of the water, it dies after a short while. A third organism Z having to breathe organs C and D which lives on the banks of ponds, lakes and rivers can survive on land as well as in water equally well.
(a) What could organism X be? Name the breathing organs A.
(b) What could the organism Y be? Name the breathing organs B.
(c) What could the organism Z be? Name the breathing organs C and D.
(d) Out of X, Y and Z, which organism is (i) amphibian, (ii) aquatic, and (iii) terrestrial?

A , B and C are three living organisms. The organism A is a unicellular fungus which can live without air. It is used in the commercial production of an organic compound P from molasses. The organism B is a unicellular animal which lives in water and feeds and moves by using pseudopodia. It breathes through an organelle Q. The organism C is a tiny animal which acts as a carrier of the malarial parasite. It breathes and respires through a kind of tiny holes R and air-tubes S in its body.
(a) What are organisms (i) A (ii) B, and (iii) C?
(b) Name (i) P (ii) Q (iii)R, and (iv) S.
