Fertilization is the process of fusion of pollen, the male gamete and egg, the female gamete. Fertilization results in the formation of a zygote. Zygote is one celled stage of an individual which divides to form embryo.

Fertilization: The process of combining the male gamete, or sperm, with the female gamete, or ovum. The product of fertilization is a cell called a zygote.

Plant Fertilization: the process of fusion of the female gamete, the ovum or egg and the male gamete produced in the pollen tube by the pollen grain. The male gametes of the flower are transferred on to the female reproductive organs through pollinators.

Egg cell or ovum: haploid female gamete (egg cell in plants, ovum or egg in animals) forming a zygote after fertilization, which gives rise to the diploid embryo. Egg apparatus: structure at the micropylar end of the embryo sac in seed plants, consisting of the egg cell and usually two synergid cells.

In plants, fertilization is a process of sexual reproduction, which occurs after pollination and germination. Fertilization can be defined as the fusion of the male gametes (pollen) with the female gametes (ovum) to form a diploid zygote. It is a physicochemical process which occurs after the pollination of the carpel.

The four main parts of a flower are the petals, sepals, stamen, and carpel (sometimes known as a pistil). If a flower has all four of these key parts, it is considered to be a complete flower.

A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Magnoliophyta, also called angiosperms). The biological function of a flower is to facilitate reproduction, usually by providing a mechanism for the union of sperm with eggs.

Most flowers have four main parts: petals, stamen (anther and filament), pistil (stigma, style and ovary), and sepals.

Flowering plants are divided into two groups – monocots and dicots.

Different types of flowers (the Angiosperms) can easily be identified by dividing them into Monocots or Dicots….The Plant Kingdom.

• Angiosperms – Flowers.
• Gymnosperms – Cones.
• Bryophytes – Mosses, Liverworts, Hornworts.
• Pteridophytes – Ferns, Horsetails and Club Mosses.
• Legumes – Beans, Peas and Lentils.
