Pollination is the transportation of pollen grains from the stamens to the flower parts by which they are produced. On the other hand, Fertilisation, also known as impregnation, is the combination of fusion of gamut to give rise to a new offspring organism and carve up its development. The continuous process cycle of fertilisation and development of the new offspring is known as sexual reproduction. When a male haploid gamete combines with the two haploid polar nuclei and forms a triploid primary endosperm nucleus, the process is known as vegetative fertilisation, and it is processed during the double fertilisation process.
What is Pollination?
Pollination transfers pollen grains from the male part, also known as anther in flower, to the female part, known as stigma. This whole process is known as pollination. Later, the fertilisation occurs as the production of seeds or mostly by the animals or wind. Pollinating agents can be of various types, such as birds, bats, water, wind plants, and insects. There are two types of pollination self-pollination and one with a different breed known as a hybrid. When the plant itself pollinates, self-pollination happens inside a closed flower. On the other hand, the pollination process between two different species produces different organisms or offsprings in the environment, also known as work in plant breeding.
After the male part, also known as anther or angiosperms, has landed on the female part, known as stigma, it develops and germinates a pollen tube which increases till it reaches an ovary. It’s two gametes, also known as gametophytes, which contain female gametes that reach down or travel down and are held back within the carpel. This whole process is considered to be double fertilisation. In the production of this double fertilisation, processes are also known as seeds made of nutrition of both embryo and tissues.
What is Fertilisation?
Fertilisation, also known as syngamy, or generative fertilisation is the process of female and male gametes producing a new organism or offspring and originating its development. The fusion of gametes before pollination is sometimes also known as fertilisation. The process of development in these organisms and the continuous cycle of these new offspring is called sexual reproduction. In the process of fertilisation, when a female and male gamete fuse to form a single cell, they form a hybrid gamete or mixed gamete of male and female by fusion together known as a zygote. Then, the zygote develops into a fully functioning being by mitosis.
The fertilisation process is necessary for all the offspring of organisms that have sexual intercourse. There are two types of fertilisation, external fertilisation, and internal fertilisation. The eggs produced and fertilised within the reproductive tract of a female are known as internal fertilisation.
On the other hand, the eggs fertilised outside the body are external fertilisation.
External Fertilisation
The process of external fertilisation generally occurs in the aquatic environment. It requires both female and male offspring to release gametes into their surroundings, generally in water. This whole process of broadcasting gametes into their surroundings by the female and male organisms or offspring is known as spawning. Mammals like fish, corals, and amphibians reproduce by external fertilisation.
Internal Fertilisation
The animal that uses the internal fertilisation process is unique in developing and defending its eggs. Sometimes the organism or the offspring are born from an egg before it is born, or sometimes it encloses in an egg upon its birth. Many birds and big reptiles used to cover their eggs with a protective shell that is resistant to damage and water loss to protect their eggs.
Fertilisation and Pollination: Difference
Pollination | Fertilisation |
Pollination is only restricted to an external process | Fertilisation can be internal or external |
The process of fertilisation takes place before the process of fertilisation | The fertilisation process takes place after The process of pollination is completed |
Pollination occurs when the male part is known as anther, which sticks to the female part, known as stigma | Fertilisation is when the male gametes and female gametes amalgamate together |
When the pollination process is done, it results in the process which directs fertilisation | The process of fertilisation leads to the manufacture of seeds |
The requirement for the pollen tube is not there | The requirement for the pollen tube is there |
Requires no external factors | It requires external factors |
Conclusion
The two main processes of producing offspring are fertilisation and pollination. Both the process is natural. The reproduction process occurs in the male part known as an anther and the female part known as the stigma in the flower; therefore, in plants, they are also considered the reproductive organs of a plant. Fertilisation is a process in which the gametes of males and females fuse to form a zygote. Pollination does not require any external factors, but fertilisation does require it.
