Introduction to Reproduction in Organisms
What is Reproduction?
Reproduction is the biological process by which organisms produce new individuals of the same species. It is essential for the continuity of life and ensures genetic inheritance from one generation to the next.
Why is Reproduction Important?
- Maintains the existence of a species.
- Helps in the transfer of genetic material (DNA).
- Promotes variation and evolution in living organisms.
Types of Reproduction
Reproduction can be broadly classified into two types:
- Asexual Reproduction – Involves a single parent and produces genetically identical offspring (clones).
- Sexual Reproduction – Involves two parents and leads to genetic variation in offspring.

Introduction – Part 1 (Class 12 / NEET)
What is Reproduction?
Reproduction is a biological process by which living organisms produce new individuals of the same species, ensuring the continuity of life.
Why is Reproduction Important?
- Maintains species continuity.
- Ensures genetic variation (especially in sexual reproduction).
- Helps organisms adapt and evolve over generations.
Types of Reproduction
Asexual Reproduction (Only 1 parent involved)
- Offspring are genetically identical to the parent (clones).
- Common in unicellular organisms and simple multicellular organisms.
Sexual Reproduction (Involves 2 parents)
- Offspring are genetically diverse.
- Involves formation of male and female gametes and fertilization.
Asexual Reproduction – Examples:
| Mode | Organism | Description |
|---|---|---|
| Binary Fission | Amoeba, Bacteria | Cell splits into two |
| Budding | Hydra, Yeast | Small bud forms & detaches |
| Fragmentation | Spirogyra | Body breaks into pieces |
| Sporulation | Fungi, Algae | Spores develop into new organism |
| Vegetative Propagation | Plants (e.g., potato, rose) | Through roots, stems, leaves |
Lifespan & Reproduction
- Lifespan: Time from birth to natural death.
- Reproduction typically occurs during the mature phase of the organism’s lifespan.
- Death is inevitable, but reproduction ensures species survival.
Key Terms to Remember:
| Term | Meaning |
|---|---|
| Clone | Offspring identical to the parent |
| Gamete | Reproductive cell (sperm/egg) |
| Fertilization | Fusion of male and female gametes |
| Zygote | First cell formed after fertilization |

A) Hydra
