PollinationPollination is defined as the process of transfer of pollen grains from the anther of a flower of a plant to the stigma of the same flower or of different flower of same plant or genetic...

What pollination? Differentiate between self-pollination and cross pollination.

Pollination is the process of transfer of pollen grains from anther to stigma of a flower.
The difference between self pollination and cross pollination are:

Self pollination	Cross pollination
It is the transfer of pollen grains from anther to stigma of same flower.	It is the transfer of pollen grains from anther to stigma of different flower.
Zygote of same identical characters are formed.	Zygote of hybrid characters are formed.

a. Binary and Multiple fusion.

Binary fusion	Multiple fusion
In this process, mother organism splits into two daughter organism.	In this process, mother organism splits into more than two daughter organisms.

b. Sperm and Ovum.

Sperm	Ovum
It is male gamete.	It is female gamete.
It is produced by male reproductive organ.	It is produced by females reproductive organs.
It is motile and smaller in size.	It is non-motile and larger in size.

A new rose plant is obtained by planting a piece of its stem in a soil. What type of asexual reproduction? Give three reasons why such method of reproduction is beneficial for farmers.

It is the natural vegetative propagation arial stem.
It is beneficial for farmers because:
- It is cheaper, easier and faster method of reproduction.
- Large number of plants can be propagated by this method.
- Plants who don't produce the viable seeds can be reproduced by it.
- Plants reproduced by this method starts yielding faster.

What is layering ? Name the various method of layering.

Layering is the artificial method of reproduction in which roots are developed on the stem while the stem is still attached to the parent plant.
The various method of layering are:
- Simple layering.
- Compound layering.
- Tip layering.
- Mound layering.
- Air layering.
