What is fertilisation in chemistry?
Fertilizers are chemical substances supplied to the crops to increase their productivity. These are used by the farmers daily to increase the crop yield. The fertilizers contain the essential nutrients required by the plants, including nitrogen, potassium, and phosphorus.
What is the process of fertilization BBC Bitesize?
Fertilisation is the process in which the nucleus of a sperm cell fuses with the nucleus of an egg cell to produce a zygote which will eventually grow into offspring.
What is fertilization in human reproduction?
Fertilization: A Sperm and an Egg Form a Zygote They each contain half the genetic information necessary for reproduction. When a sperm cell penetrates and fertilizes an egg, that genetic information combines.
What is fertilization in environmental science?
Fertilization (nutrient enrichment) is the method of adding nutrients such as phosphorus and nitrogen to a contaminated environment to stimulate the growth of the microorganisms capable of biodegradation.
What is fertilization for Class 7th?
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.
What is fertilization and example?
Sexual reproduction starts with the combination of a sperm and an egg in a process called fertilization. This can occur either inside (internal fertilization) or outside (external fertilization) the body of the female. Humans provide an example of the former whereas seahorse reproduction is an example of the latter.
What is fertilisation GCSE biology?
Fertilisation is the fusion of the nucleus of a male gamete with the nucleus of a female gamete, producing a new cell called a zygote .
What is fertilization in biology class 10?
(a) Fertilization: Fertilization is the process by which male and female gametes are fused together, initiating the development of a new organism.
What are the types of Fertilisation?
Based on this, fertilization is of two types – internal and external fertilization.
What is the process of fertilisation?
Fertilisation is the fusion of the nucleus of a male gamete with the nucleus of a female gamete, producing a new cell called a zygote. This then matures into an embryo.
What is the difference between sexual reproduction and fertilisation?
Sexual reproduction involves the joining of two sex cells (gametes) – the sperm (male gamete) and the egg/ovum (female gamete). Fertilisation is the fusion of a haploid sperm nucleus and a haploid egg nucleus to form a diploid (normal chromosome number) zygote. A zygote is the first cell of a new individual. Fertilisation occurs in the oviduct.
What happens to the nuclei of gametes during fertilisation?
During this process the nuclei of the male and female gametes are fused in order to create a zygote. This process is known as fertilisation. Gametes contain half the number of chromosomes of all other cells in the organism. This means they are haploid.
How does secondary fertilization occur in flowering plants?
In flowering plants, a secondary fertilization event takes place. Two sperm are transferred from each pollen grain, one of which fertilizes the egg cell to form a diploid zygote. The nucleus of the second sperm cell fuses with two haploid nuclei contained within a second female gamete called the central cell.
