Two very small organisms X and Y both reproduced by the method of budding .Organism X is industirally very important because it is used in making alcohol from sugar. It is also used in making bread. Organism Y is a tiny animal having tentacles which lives in water.
c) To which class of organisms does X belong?

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 water, it dies after a short while. A third organism Z having breathing orgains 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 organism Y be? Name the breathing orgains B. (c) What could 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 ?

X and Y are the two types of organisms which are found in forests. Both types of organisms are considered to be cleansing agents of the forest environment in their own way. The organisms like X eat up the dead animals in the forest whereas the organisms like y break down the dead animals into simple substance which can be re-used for the growth of plants. Name one organisms like X.

A, B and C are three living organisms. The organism A is a unicellullar 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 an tiny animal which acts as a carrier of 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 (c) Which organism/organisms undergo aerobic respiration ? (d) Which organism/organisms undergo anaerobic respiration ?
