Question

Explain the term ‘fertilization’. Describe the process of fertilization in human beings.

Answer 1

Answer:

Fertilization in Human Beings: it’s Process and Significance! Fertilization (also called syngamy) involves the fusion of haploid male and female gametes to form diploid zygote. Fertilization in the human beings is internal and takes place at the ampullary-isthmic junction of fallopian tube of the female.

Answer 2

Fertilisation:

• The process of fusion of male gamete and female gamete is called fertilisation.
• The gametes are haploid in nature and they are fused to produce zygote which is diploid in nature.

Fertilisation in human beings:

• In humans, the male gamete is sperm which is produced in testes male sex organ.
• During intercourse of male and female organism, copulation takes place in which the male sex sends sperms directly into the reproductive tract of female.
• The sperm and egg fuses in female organisms and formed into zygote.
• The zygote develops into embryo and travels to uterus through fallopian tube or oviduct.
• When embryo is embedded on uterine lining, then the female human being is termed as pregnant.
• The embryo get food and oxygen through uterine lining and develops into fetus/foetus after eight weeks.
• Later, it develops ears, nose, eyes and finger.
• After 280 days, then baby is given birth through vagina of mother organism.
