Sometimes they contain a supply of nutrients. This process is unique and results in a mass of spores that are held up on a tapering stalk. Living organisms … In the free-swimming stage, Euglena reproduce rapidly by a type of asexual reproduction method known as binary fission. The algal component provides food to host paramecium … Understands the signifi cance of asexual reproduction.

Amoebiasis is characterized by pains in the … Within just a few days lots of Amoeba proteus will be caught and spawned in the jar. After several cycles of reproduction, when unfavorable conditions for a vegetative individual come, it is covered with a shell, forming a cyst. Amoeba proteus reproduces by a process called binary fission, which is a type of asexual reproduction. Students can solve NCERT Class 12 Biology Reproduction in Organisms MCQs Pdf with Answers to know their preparation level. L iving organisms show a life cycle involving birth, growth, development, maturation, reproduction and death. In favorable conditions, paramecium can undergo asexual multiplication for at least three times a day. During starvation, the amoeba cells come together to form aggregates that in turn elongate for form a migratory slug composed of over 100,000 cells.
