To study Binary Fission in Amoeba.
Budding in Yeast and Hydra, and to record observation and draw labelled diagrams.
Amoeba is a protozoa that lives in water and has an irregular shape.
In the centre of the Amoeba dense nucleus is seen.
In the second stage, Amoeba shows the nucleus division, i.e., karyokinesis.
In the third stage, we can see the cell body division, i.e., cytokinesis.
In the fourth stage, two daughter cells of Amoeba are formed.
The given slides showed the division of a single cell body into two equal halves. The division of nucleus and cell body are seen which led to the formation of two daughter cells. Hence, the kind of reproduction seen in Amoeba is binary fission.
Yeast is oval or spherical.
It is a unicellular organism.
In the second stage, yeast shows a small growth on it called ‘bud’.
In the third stage, yeast shows that in some situations many such chains of buds are seen on the parent cell. This process is called ‘budding’.
On maturity the buds get separated from the parent cell to form and grow’ as a new organism. This process is called budding.
The given slides showed the small growth (bud) of yeast. These buds on maturity separate from the parent cell and grow as a new organism, hence, yeast shows budding.
Bulblike projections called buds arise from the cell membrane of the parent body.
Mature hydra cells are larger and elongated in shape and have finger-like projections.
The nucleus of the parent cell divides and one of the daughter nuclei passes into the bud.
Finally, the bud is separated from the parent body into a new individual.
The given slides showed the buds arise on an individual which get separated on maturity to become a new individual.
