During a biology practical, teacher asked the students to study binary fission in Amoeba with the help of
permanent slides. Draw the different stages that were observed by the students
Answers
Experiment:
Objective:
To study (a) binary fission in Amoeba
Apparatus and Materials Required:
Permanent slides of Amoeba showing binary fissionand a compound microscope.
Procedure.
1. Observe each permanent slide first under the low-power magnification and then under the high-power magnification of a compound microscope.
2. Draw diagrams and compare their features.
Observations:
Binary fission in Amoeba:
1. In this division, two similar individuals are formed from a single parent.
2. A mature Amoeba cell is larger. Its nucleus elongates and gradually divides amitotically into two.
3. The division of the nucleus is followed by the division of the cytoplasm.
4. Thus two new amoebae are formed from a single parent and the parent’s identity is lost.
Result:
The prepared slides show asexual reproduction in which only one individual is involved in the production of new individuals.
