Two very small organisms X and Y both reproduce by the method of budding. Organism X is industrially very important because it is used in making alcohol from sugar. It is also used in making bread. Organism Y lives in freshwater. If organism Y gets cut into a number of parts accidently, each cut part can grow to form complete organism.(a) What are organisms X and Y?
(b) What is the name of the process in which X converts sugar into alcohol?
(c) To which class of organisms does X belong?
(d) Name an important body feature of organism Y.
(e) Which organism is multicellular and which one is unicellular?
(a) Organism X is Yeast (because it reproduces through budding and used in industrial production of alcohol and bread).
Organism Y is Hydra (because it reproduces through budding and lives in freshwater).
(b) Organism X (Yeast) converts sugar into alcohol through the process of fermentation.
(c) Organism X (Yeast) belongs to the family of Fungi.
(d) An important body feature of Organism Y (Hydra) is it possess tentacles over one end of its cylindrical-shaped body.
(e) Hydra is a multicellular organism while Yeast is an unicellular organism.
