what do you mean by fertisation

Answer:
Fertilisation occurs when a sperm fuses with the female act during intercourse and further forms an egg that gets implanted in uterus of the female.
Fertilization takes place in the fallopian tubes, which connect the ovaries to the uterus. Fertilization happens when a sperm cell successfully meets an egg cell in the fallopian tube. Once fertilization takes place, this newly fertilized cell is called a zygote.
In animals, there are two types of fertilization, internal and external.Internal fertilization happens in the female body. External fertilization happens outside of the body. Mammals, birds, and reptiles use internal fertilization.
The three main types of plant fertilization - porogamy, chalazogamy, and mesogamy are distinguished by how the pollen tube enters the ovule. Of these three, porogamy is most common. Porogamy occurs when a pollen tube enters the ovule through a micropyle, or minute opening in the ovule; this the most common form of plant fertilization. In chalazogamy, pollen tubes enter the ovule through the chalaza, located opposite the micropyle, and in mesogamy, these tubes enter the ovule through its integument (outermost layer or layers).
