Modes of Reproduction
- Reproduction with the help of sex organs are called sexual reproduction.
- Flowers are the reproductive parts of a plant .
Transfer of pollen grains from anther to stigma of a flower is called pollination
The transfer of pollengrains from anther to stigma of the same flower is called self pollination
Transfer of anther to stigma of the flower in the different plant or different flower in the same plant is cross pollination.
Fusion of male and female gamete is called Fertilisation and the cell which results after it is called a Zygote
New plants are obtained without production of seeds or spores.
It is a type of asexual reproduction in which new plants are produced from the vegetative parts of the plant.Example - Rose
Small bulb like projection coming out from some single celled organism that gradually grows and gets detached from parent cell and forms a new organism.Example - Yeast
During fragmentation an Organism breaks up into fragments and these fragments or pieces grow into new individuals.Example - Spirogyra
The spores are asexual reproductive bodies. Under favourable conditions, spore germinates and develops into a new individual.Example - Fungus
- All living Organisms reproduce their own kind.
- In Plants there are two modes of reproduction- sexual and Asexual.
- Flower is the reproductive part of a plant.
- Pollination is the transfer of pollen grains from the Anther to the Stigma of the same or another flower.
- The fusion of male and female gametes is called Fertilisation.
