EXCERPT

All organisms multiply or reproduce their own kind.
In plants there are two modes of reproduction, asexual and sexual.
There are several methods of asexual reproduction such as fragmentation, budding, spore formation and vegetative propagation.
Sexual reproduction involves the fusion of male and female gametes.
Asexual reproduction is the process in which new plants are produced by involving only one parent.
Flowerless plants such as algae reproduce by fragmentation; yeasts reproduce by budding, while moulds and mosses reproduce through spores.
Vegetatively, plants reproduce with the help of roots, bulbs, rhizomes, tubers, corms, and adventitious buds.
There are many artificial methods by which plants multiply. These include cutting, grafting, and layering.
Flower is the reproductive part of a plant.
A flower may be unisexual with either the male or the female reproductive parts.
A bisexual flower has both the male and the female reproductive parts.
The male gametes are found inside the pollen grains and female gametes are found in the ovule.
Pollination is the process of transfer of pollen grains from the anther of one flower to the stigma of the same or another flower.
Pollination takes place in plants with the help of wind, water and insects.
The fusion of male and female gametes is called fertilization.
Fertilized egg is called zygote. Zygote develops into an embryo.
Fruit is the mature ovary whereas ovule develops into a seed, which contains the developing embryo.
Seed dispersal is necessary to separate the seed from the parent plant so that the seed can grow into a new plant.
