Question

Enumerate the differences between asexual and sexual reproduction. Describe the types of asexual reproduction exhibited by unicellular organisms.

Accepted Answer

Features Asexual Reproduction Sexual Reproduction

Gamete It does not involve formation and fusion of gametes. It involves formation and fusion of gametes.

Parents It is uniparental. It is generally biparental.

Cell type Reproductive units are somatic cells of parent. Reproductive units are germ cells of parent.

Features Asexual Reproduction Sexual Reproduction

Cell division It involves only mitotic divisions. It involves meiosis during gamete formation.

Offsprings Offsprings are genetically similar to parents. Offsprings are genetically different from parents.

Complexity Fast and simple process. Slow, elaborate and complex process.

The types of asexual reproduction exhibited by unicellular organisms are:

i) Binary fission: Many single-celled organisms reproduce by binary fission, where a cell divides into two halves and each daughter cell rapidly grows into an adult. e.g. Amoeba, Paramecium

ii) Multiple fission: In this process, the parent body divides into many similar daughter individuals. e.g. Amoeba

iii) Budding: In this, small buds are produced. It grows in size and gets separated and mature into a new organism. e.g. yeast

iv) Zoospore formation: Zoospores are motile spores which possess flagella produced inside the zoosporangia. e.g. Chlamydomonas
