Question

Experiment - to study binary fission in amoeba and budding in yeast with the help of prepared slides?

Answer 1

Apparatus and Materials Required:

Permanent slides of Amoeba showing binary fission

yeast in budding

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:

In this division, two similar individuals are formed from a single parent. A mature Amoeba cell is larger. Its nucleus elongates and gradually divides amitotically into two. After the division of nucleus the division of cytoplasm occurs. 

yeast:

In this reproduction, bulb like projections called buds arise from the parent body. Mature yeast cells are larger, and spherical or oval in shape. The nucleus of the parent cell divides and one of the daughter nuclei passes into the bud.

Answer 2

Explanation:

Yeast is a unicellular organism which produces a chain of cells attached to the parent cell. Step 1: The slide is placed under compound microscope. Step 1: The slide is focused under low power and later high power of compound microscope. Step 2: The stages in binary fission and budding are observed carefully.
