Binary Fission in Amoeba and Budding in Yeast

Introduction; How Does Binary Fission in Amoeba and Budding yeast happen?

In binary fission, a single-celled organism duplicates its genetic material, then splits in two. The process is similar to mitosis, the process by which normal cells divide.

In budding yeast, the process of binary fission is more complicated. The yeast cell first duplicates its genetic material, then forms a small bud on its surface. The bud grows until it separates from the parent cell and becomes a new, independent yeast cell.

Amoeba

An amoeba is a single-celled microscopic organism. Amoebas are found in both salt water and fresh water. They are shape-shifters and can move by using pseudopods, which are long, thin extensions of the cell membrane.

Classification of Amoeba

There are many different types of Amoeba, but they can generally be classified by their shape.

Some amoebas are unicellular and some are multicellular.

Amoebas that are unicellular typically have a blob-like shape.

Amoebas that are multicellular typically have a pseudopodia-like shape.

There are also several different types of amoeba based on their method of locomotion.

Amoebas that use pseudopodia for locomotion are typically called “true” amoebas.

Amoebas that use flagella for locomotion are typically called “salt water” amoebas.

There are also several different types of amoeba based on their mode of nutrition.

Amoebas that are heterotrophic are typically called “true” amoebas.

Amoebas that are autotrophic are typically called “salt water” amoebas.

Binary Fission in Amoeba Happens Through Various Steps, They Are:

1. The amoeba begins to divide by mitosis.

2. The nucleus divides, and the cytoplasm divides.

3. The amoeba splits in two, and each half becomes a new amoeba.

The Shape of Amoeba Under Compound Microscope

When viewing an amoeba under a compound microscope, it will generally appear as a round or oval shape with a smooth surface. Its size will also vary, depending on the species. Some amoebas may be smaller than a pinhead, while others may be larger than a grape. Amoebas typically have a single nucleus and one or more contractile vacuoles, which are used to expel excess water from the cell. They may also have other organelles, including Golgi bodies, lysosomes, and mitochondria.

Binary Fission in Amoeba

Binary fission is a form of asexual reproduction where a single celled organism splits in two. This process begins with the DNA in the nucleus of the cell dividing into two copies. The cytoplasm of the cell then splits in two, and the two new cells each grow a copy of the original cell’s nucleus.

Budding:

Budding is a type of asexual reproduction found in some plants and fungi. In budding, a small protrusion called a bud forms on the surface of the parent organism. The bud grows until it separates from the parent and becomes an independent organism.

How Budding in Yeast Occurs:

In yeast, budding is a type of asexual reproduction. It occurs when a small bud, or daughter cell, separates from the parent cell. The bud grows until it is large enough to survive on its own, and then it separates from the parent cell completely.
