Reproduction means creating new offspring. There are two main types: sexual and asexual reproduction. In sexual reproduction, an organism mixes genetic information from both parents, making the offspring unique. In asexual reproduction, one parent produces a copy of itself, resulting in an offspring that is genetically identical.
What is Reproduction?
Reproduction is the way living things make new living things that are like themselves. This process helps keep species alive through generations. It is an essential part of life on Earth.
Let's look at what reproduction is, its different types, and how it happens in plants and animals.
Types of Reproduction
There are two main types of reproduction:
- Asexual Reproduction
- Sexual Reproduction
Asexual Reproduction vs. Sexual Reproduction
Asexual Reproduction:
Asexual reproduction is a type of reproduction where offspring are produced from a single parent, without the involvement of gametes (sex cells). Here's how it works:
- Process: Organisms reproduce by simple cell division, budding, or fragmentation.
- Genetic Material: Offspring are genetically identical to the parent (clones).
- Examples: Examples include budding in yeast, binary fission in bacteria, and regeneration in starfish.
Sexual Reproduction:
Sexual reproduction involves the fusion of male and female gametes (sperm and egg) to produce offspring with genetic variation. Here are its key aspects:
- Process: It requires the formation of gametes through meiosis and their fusion during fertilization.
- Genetic Variation: Offspring inherit traits from both parents, leading to genetic diversity.
- Examples: It is common in most animals, plants, and some fungi.

Frequently Asked Questions
Reproduction is the process by which organisms produce offspring, ensuring the continuation of their species.
In Class 12, reproduction is studied in detail, covering both sexual and asexual methods in plants and animals.
The three types of reproduction are sexual reproduction, asexual reproduction, and vegetative reproduction.
Reproduction in plants involves the production of new plants through seeds, spores, or other plant parts.
Sperm is released in females during sexual intercourse, where it travels through the vagina to reach the egg.
Sperm is transferred from the male to the female through the process of ejaculation during sexual intercourse.
Reproduction in pregnancy refers to the process where a fertilized egg develops into a baby inside the mother's womb.
The reproductive process in plants involves pollination, fertilization, and seed formation to produce new plants.
The five steps of plant reproduction are pollination, fertilization, seed development, seed dispersal, and seed germination.
