What happens when a gamete is fertilized?
Fertilization is defined as the union of two gametes. During fertilization, sperm and egg fuse to form a diploid zygote to initiate prenatal development. In mammals, fertilization involves multiple ordered steps, including the acrosome reaction, zona pellucida penetration, sperm–egg attachment, and membrane fusion.
Where does fertilization of gametes occur?
fallopian tubes Fertilization is the fusion of a spermatozoan and an oocyte takes place in one of the oviducts or fallopian tubes. It is necessary for the gametes to be delivered to the fallopian tubes in a fertilizable state.
Which is formed after fertilization of the male and female gamete is called?
The male gamete, or sperm, and the female gamete, the egg or ovum, meet in the female's reproductive system. When sperm fertilizes (meets) an egg, this fertilized egg is called a zygote (ZYE-goat). The zygote goes through a process of becoming an embryo and developing into a fetus.
What is a fertilized gamete called?
zygote, fertilized egg cell that results from the union of a female gamete (egg, or ovum) with a male gamete (sperm).
What is the fertilization process?
The stages of fertilization can be divided into four processes: 1) sperm preparation, 2) sperm-egg recognition and binding, 3) sperm-egg fusion and 4) fusion of sperm and egg pronuclei and activation of the zygote.
What is called fertilization?
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.
What happens during conception and implantation?
During fertilization, the sperm and egg unite in one of the fallopian tubes to form a zygote. Then the zygote travels down the fallopian tube, where it becomes a morula. Once it reaches the uterus, the morula becomes a blastocyst. The blastocyst then burrows into the uterine lining — a process called implantation.
What is the difference between fertilization and conception?
Conception means beginning of pregnancy from the union of sperm and ovum. It is also called as 'fertilization' and it marks the beginning of development of a new individual in the womb of mother. Gestation means carrying the embryo inside the female's uterus. It is the time period from conception to birth of the child.
What is formed after fertilization?
The result of fertilization is a cell (zygote) capable of undergoing cell division to form a new individual.
What is zygote formation?
A zygote is the first diploid cell that is formed by the fusion of male and female gametes resulting in the formation of an embryo. The zygote stage development occurs in the first week of fertilization.
What is the process of fertilization?
During fertilization, the sperm and egg unite in one of the fallopian tubes to form a zygote. Then the zygote travels down the fallopian tube, where it becomes a morula. Once it reaches the uterus, the morula becomes a blastocyst. The blastocyst then burrows into the uterine lining — a process called implantation.
What is the process of making gametes called?
Gametogenesis is the production of gametes from haploid precursor cells. In animals and higher plants, two morphologically distinct types of gametes are produced (male and female) via distinct differentiation programs. Animals produce a tissue that is dedicated to forming gametes, called the germ line.
What are the 4 steps of conception?
The stages of fertilization can be divided into four processes: 1) sperm preparation, 2) sperm-egg recognition and binding, 3) sperm-egg fusion and 4) fusion of sperm and egg pronuclei and activation of the zygote.
What are the process of fertilization in human?
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. The sperm travels through the fallopian tube and penetrates the zona pellucida layer of the ovum (female egg) and fuses with it which forms zygote (fertilized egg).
What happens in conception step by step?
To become pregnant, the following steps must occur: Sperm transport — The sperm must be deposited and transported to the site of fertilization. Egg transport — Ovulation must occur and the egg must be "picked up" by the tube. Fertilization and embryo development — Union between the sperm and egg must result.
What defines conception?
Medical Definition of conception 1a : the process of becoming pregnant involving fertilization or implantation or both. b : embryo, fetus. 2a : the capacity, function, or process of forming or understanding ideas or abstractions or their symbols. b : a general idea. More from Merriam-Webster on conception.
What does conceived mean?

What is fertilization and zygote?
During fertilization, the sperm and egg unite in one of the fallopian tubes to form a zygote. Then the zygote travels down the fallopian tube, where it becomes a morula. Once it reaches the uterus, the morula becomes a blastocyst. The blastocyst then burrows into the uterine lining — a process called implantation.
What is meant by Fertilisation?
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.
What is spermatogenesis and oogenesis?
Spermatogenesis and oogenesis are the processes of formation of male and female gametes. Spermatogenesis leads to the formation of sperms, whereas oogenesis helps in the formation of ova. The fertilization of sperm and ova leads to the formation of a zygote which further develops into an embryo.
What involves fertilization?
Fertilization is a complicated multistep molecular process where two highly methylated and specified haploid gametes, spermatozoon and oocyte, are coming together forming a male and a female pronucleus, respectively, and culminating in the fusion of the two pronuclei giving rise to the formation of the zygote.
What happens at conception and implantation?
During fertilization, the sperm and egg unite in one of the fallopian tubes to form a zygote. Then the zygote travels down the fallopian tube, where it becomes a morula. Once it reaches the uterus, the morula becomes a blastocyst. The blastocyst then burrows into the uterine lining — a process called implantation.
When can conception occur?
Conception (when the egg is fertilized by the sperm) can take place as soon as three minutes after sex or it may take up to five days. Implantation (when the fertilized egg attaches to the uterine wall) occurs five to 10 days after fertilization—which means it can happen anywhere from five to 15 days after you had sex.
What is conception vs fertilization?
Some of these laws say that pregnancy begins at fertilization, others at implantation. Several use the term "conception," which is often used synonymously with fertilization but, medically, is equated with implantation.
What is an example of conception?
The definition of conception is the process of becoming pregnant or the origin of anything. An example of conception is when the egg and sperm meet and form a life. An example of conception is the creation of a new marketing technique. The ability to form or understand mental concepts and abstractions.
When did you conceive meaning?
The date of conception is the day on which a person's baby is conceived. The calculator also estimates a possible range of days during which sexual intercourse might have led to conception based on sperm being viable for 3-5 days within a woman's body.
What is fertilisation in reproduction?
fertilization, union of a sperm nucleus, of paternal origin, with an egg nucleus, of maternal origin, to form the primary nucleus of an embryo.
What is another term for fertilisation?
creation by the physical union of male and female gametes; of sperm and ova in an animal or pollen and ovule in a plant. synonyms: fecundation, fertilization, impregnation.
What is gamete oogenesis?
Oogenesis. Oogenesis describes the production of female gametes (ova) within the ovaries (and, to a lesser extent, the oviduct) The process begins during foetal development, when a large number of primordial cells are formed by mitosis (~40,000)
What is fertilization development?
A baby goes through several stages of development, beginning as a fertilized egg. The egg develops into a blastocyst, an embryo, then a fetus.
