producing gametes

Fertilisation is the fusion of the female gamete (Egg or Ovum) produced in the embryosac and the male gamete produced in the pollen tube by the pollen grai..

Sexual reproduction is seen in nearly all animals. In animals reproduction also involves production of gametes that are haploid cells . In unicellular organisms like the protozoans, the gamete-producing individuals are called gametocytes. The gametes may be similar - i..

During the formation of gametes, the females will have only one type of gametes, all with one X chromosome. However, the males will produce two types of gametes or sperms, half with X chromosome and half with Y chromosome. Thus the sex of a zygote is de..

In flowering plants, flowers have taken the place of conventional sex organs, and the ovules which later on develop into seeds are enclosed within an ovary. The sexual reproduction in angiosperms involves the fusion of two gametes, the male and the female. The male gametes are h..

The pollen grains which produce the male gametes and the ovules which bear the female gametes are borne on different structures. It therefore becomes necessary that for sexual union to occur, the pollen grains must be transferred to the stigma. The transfer and d..

is a condition, which describes the nature of a plant based on its genetic composition. A homozygous plant is one, which has both the factors responsible for the same characters. Such a plant produces only one type of gametes..

Gametogenesis - Sexual reproduction involves the fusion of two haploid gametes to form a diploid individual. The process by which gametes are produced in the gonads is known as gametogenesis. Gamete formation starts at puberty, an average of 9 - 11 years in g..

Sex Determination - During the formation of gametes, the females will have only one type of gametes, all with one X chromosome. However, the males will produce two types of gametes or sperms, half with X chromosome and half with Y chromosome. Thus the sex of ..
