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. (c) Which organism/organisms undergo aerobic respiration? (d) Which organism/organisms undergo anaerobic respiration?
