Reproduction in organisms

Asexual Reproduction (Group A)

We know that all organisms produce offsprings of their own kind. The process by which parents give rise to new individuals is known as reproduction. Plants also reproduce like all other organisms. What parts of plants are involved in reproduction?

Vegetative and reproductive parts of plants

Vegetative parts of plants are those which do not participate in the process of reproduction. The plant parts which give rise to new plants are known as reproductive parts. The given table lists the various vegetative and reproductive parts of plants.

Leaf

The flower is the reproductive part of a plant. It has either or both the male and female parts.

How does a plant reproduce?

There are two types of reproduction in plants.

  • Asexual reproduction is the process by which a plant gives rise to a new plant without producing seeds or spores.
  • Sexual reproduction is the process by which a plant gives rise to a new plant by producing seeds. When a plant reaches a certain period of its growth, it starts bearing flowers. The flowers then give rise to fruits, which contain seeds. When animals eat these seeds, they discard them, which later germinate to give rise to a new plant.

Let us now study how each plant part takes part in asexual reproduction.

Vegetative propagation is a type of asexual reproduction, where a new plant is produced from the roots, stem, leaves, and vegetative buds.

Plants produced through asexual reproduction or vegetative propagation

  • take less time to grow, and bear fruits and flowers earlier than plants produced through sexual reproduction.
  • are exact copies of the parent plant whereas plants produced through sexual reproduction show characteristics of both the parents.

Asexual reproduction in plants takes place by the following methods:

  • Budding
  • Fragmentation
  • Spore formation
  • Vegetative propagation

Budding

It involves the formation of a new individual from a protrusion called the bud. It is very common in plants and in yeasts. In yeast; the cells divide rapidly at a specific site and develop as an outgrow…
