Reproduction (or procreation or breeding) is the biological process by which new individual organisms – “offspring” – are produced from their “parents”. Reproduction is a fundamental feature of all known life; each individual organism exists as the result of reproduction. Reproduction is the sine-qua-non of ‘Continuity of Life’ and without it, all life will cease to exist. This article is based on reproduction in plants.
There are two forms of Reproduction: Asexual and Sexual. In asexual reproduction, an organism can reproduce without the involvement of another organism; while Sexual reproduction typically requires the sexual interaction of two specialized organisms, with typically a male fertilizing a female of the same species to create offspring organisms whose genetic characteristics are derived from those of the two parental organisms.
Reproduction in plants is no different. It takes place via both Sexual and Asexual mechanisms and differs according to the plant species.
Parts of the Reproductive System in Plants:
Process of Sexual Reproduction in Plants:
The sexual reproduction ins plants is carried out majorly by the process of Pollination. It is a process through which the pollen grain from an anther (male gamete) lands on to the stigma and gradually mates with the ovule (female gamete
Pollination can be of two types:
Self Pollination Cross Pollination
Pollen grains are transferred to the stigma of the same flower Pollen grains are carried to stigma of another flower of the same plant type
Occurs in bisexual plants having anther and stigma maturing at same time Occurs in unisexual flowers or in bisexual flowers having anther and stigma maturing at different times
Example: Plants like Wheat, Peas Example: Plants like Lady Finger, Tomato, Brinjal
Process of Fertilization:
The difference between asexual reproduction and sexual reproduction
Asexual Reproduction Sexual Reproduction
Reproduction occurs through a single parent plant Both male and female parent plants are required
It occurs in unisexual plants It can occur in only bisexual plants
Morphologically underdeveloped plants use asexual mechanism Morphologically developed plants use sexual mechanism
Reproductive parts are not present Fully developed reproductive parts such as anther and pistil are present
In most methods, original parent ceases to exist after process of reproduction The original parent continues to exist after process of reproduction
The characteristics of the offsprings are identical to parent plant The characteristics of the offsprings are derived from both the parent plants.
No requirement of seeds Seeds are required to produce new plants
