- Binary fission
- Multiple fission
Draw a labelled diagram to show that particular stage of binary fission in amoeba in which its nucleus elongates and divide into two and a constriction appears in its cell membrane.
Name the type of asexual reproduction in which two individuals are formed from a single parent and the parental identity is lost. Draw the initial and the final stages of this type of reproduction. State the event with which this reproduction starts.
A student has to focus his compound microscope to observe a prepared slide showing different stages of binary fission in Amoeba. The steps he is likely to follow are listed below in a haphazard manner:
I. Adjust the diaphragm and the mirror of the microscope so that sufficient light may enter to illuminate the slide.
II. Fix the slide on the stage carefully.
III. Adjust the microscope to high power and focus.
IV. Adjust the microscope to low power and focus.
The correct sequence of the above steps to observe the slide under the microscope is
(A) I, II, IV, III
(B) II, I, IV, III
(C) II, IV, I, III
(D) I, IV, II, III
For binary fission, Amoeba required .................... parent cells.
Study the following diagrams showing various stages of binary fission in Amoeba:
The correct sequence of these diagrams should be:
(A) I, IV, III, II, V
(B) I, III, IV, II, V
(C) I, II, IV, III, V
(D) I, II, III, IV, V
List any two modes of asexual reproduction in animals.Under which mode of reproduction is vegetative propagation placed and why?
