Question

Which of the following reproduces using fission?
1. Rhizopus
2. Hydra
3. Planaria
4. Amoeba

Answer 1

Correct Answer - Option 4 : Amoeba

Concept

• Amoeba is a unicellular organism that has the ability to alter its shape.
• Grouped under the Kingdom Protista.
• Commonly found in water bodies like ponds and lakes.
• Based on records amoeboid organism was produced in 1755 by August Johann Rösel von Rosenhof.
• The structure of Amoeba consists of cytoplasm, plasma membrane, and nucleus.

​Explanation

• Amoeba, Paramecium, and Bacteria use binary fission as a means of propagation.

• Binary fission is an asexual mode of reproduction.

• In binary fission, The parent organism divide to form 2 new organism.

• Bacteria is the most common example for binary fission.

• The simultaneous occurring of DNA replication and segregation is an important feature if binary fission.

Multiple fission	Process of asexual reproduction. Many daughter cells are produced from the parent cell. Sporozoans and algae are examples of multiple fission.
Sexual reproduction	Production of a new organism from two parents using their sex cells or gametes. Sexual reproduction is the most common mode of reproduction in eukaryotes, such as animals, fungi, and plants.
Budding	Budding is the formation of a bud from an organism and the bud is capable of developing into a new individual. Hydra and yeast are examples of budding.
