Fertilisation
>double fertilisation..
>double fertilisation..Post fertilisation changes:
As a result of fertilisation, the following changes are observed in a flower: 1. A diploid zygote is formed and develops into an embryo which is the future plant. 2. The triploid endosperm tissue serves as a source of nutrition for the developing embryo. 3. The ovule becomes s..
Special Modes of Reproduction
In angiosperms, the fruits are usually formed after the process of fertilisation. In certain plants, however, the fruits are formed without the act of fertilisation. Such fruits are called parthenocarpic fruits and the phenomenon is known as parthenocarp..
c. Self incompatibility:
In some plants even if self pollination takes place, fertilisation is prevented as the pollen fail to germinate. Such plants can produce seeds only after cross pollination. E.g., Brassi..

Summary

Pollination refers to the transference of pollen grains from the anther of a flower to the stigma of the flower. It occurs..
Chemical Fertilizers
These are nutrient supplements for plants manufactured in fertilizer factories from chemicals. They are nutrient specific i.e., they may provide only nitrogen, only phosphorus or only potassium to the soil. They are often used when a particular nutrient is required in the soil for a parti..
