Fertilisation results in the formation of a/an:

The correct answer is Zygote.

Key Points

• Fertilization is the process of fusion of male gametes with female gametes, it is also called Syngamy.
  • It results in the formation of a diploid zygote. Hence option 1 is correct.
  • This zygote develops in an embryo.
• There are two types of fertilization: External fertilization and Internal fertilization.
  • When the process of fertilization takes place outside the body of an organism, for example, in aquatic organisms like fishes, algae, and amphibians, it is called External fertilization.
  • When the process takes place inside the body of an organism, for example, in most terrestrial organisms like fungi, higher animals, and the majority of plants such as bryophytes, and gymnosperms, is called Internal fertilization.
• After fertilization, the ovary grows into a fruit and other parts of the flower fall off. The fruit is the ripened ovary.
  • The seeds develop from the ovules. The seed contains an embryo enclosed in a protective seed coat.

Additional Information

gamete

• A gamete is a reproductive cell of an animal or plant. In animals, female gametes are called ova or egg cells, and male gametes are called sperm.
  • Ova and sperm are haploid cells, with each cell carrying only one copy of each chromosome. During fertilization, a sperm and an ovum unite to form a new diploid organism. 

Ovary

• Ovary a of a pair of female glands in which the eggs form and the female hormones estrogen and progesterone are made. These hormones play an important role in female traits, such as breast development, body shape, and body hair.

germ

• A germ cell is a cell that develops into a reproductive cell, which is an egg in females and a sperm in males.
