Seeds can be dispersed by:
• Wind
• Water
• Animals
• Explosions
There are two types of pollination.
• Self-pollination
• Cross-pollination
The transfer of pollen grains from anther to stigma is called pollination.
Asexual reproduction is a mode of reproduction in which a new offspring is produced by a single parent.
The stages of sexual reproduction in plants are:
• Pollination
• Fertilization
• Seed formation
• Seed dispersal
• Germination
A species is a group of similar living things that can reproduce together and have offspring that can also reproduce.
Reproduction is a process by which an organism reproduces an offspring that is biologically similar to the organism.
Sexual reproduction of plants involves the fusion of male and female reproductive parts. The male gametes are produced in the anthers of the flower, while the female gametes are produced in the ovary.
Stamen is the male reproductive part of a flower. Stamen includes anther and filament.
Pistil is the female reproductive part of a flower. Pistil includes stigma, style and ovary.
Pollination is the process where pollen grains from a flower's male part (stamen) are transferred to the female part (pistil) of another flower.
After fertilization sepals, petals, anther and filament dry up and fall. Zygote develop into embryo. The Ovule containing embryo forms seed.
A seed consists of three parts.
Seed coat
It is the outer covering of seed that protects the seed.
Cotyledon
It is present inside the seed and surrounds the growing embryo (baby plant).
Embryo
It also supplies food to the new plant. When the conditions are right, embryo grows into a new plant.
This method involves growing new plants from cells or tissues of the parent plant. The cells or tissues are taken from the parent plant and placed in a sterile medium. The cells or tissues will eventually divide and grow into new plants.
