A filamentous alga X is found in ponds, lakes and slow-moving streams. The filament of this alga simply breaks into two(or more) pieces on maturing and each piece then grows to become a complete new alga.(a) Name an alga which X is likely to be.
(b)What is the colour of X?
(c)What is the method of forming new algae by the breaking of parent alga known as?
(d)An Amoeba also breaks up to form two daughter Amoebae. What is the difference in the splitting of Amoeba and splitting of this alga as a method of reproduction?
(e)Name one marine animal which reproduces in the same way as alga X.
(a) A filamentous alga X found in ponds, lakes and slow-moving streams is likely to be spirogyra.
(b) The color of spirogyra is green.
(c) The method of forming new algae by the breaking of parent alga known as fragmentation.
(d) The difference in the splitting of Amoeba and splitting of this alga is their method of reproduction.
Amoeba, a unicellular organism, splits by the process of fission while, splitting of algae, multicellular organisms, is carried out by the process of fragmentation.
(e) A marine animal that reproduces by the fragmentation method, similar to spirogyra is a sea anemone.
