Reproduction is the process by which a living organism creates a likeness of itself. The process may be either asexual—meaning that an organism reproduces by itself alone—or sexual—which requires both male and female sex cells.

What are the two types of reproduction?
There are two types of reproduction: asexual and sexual reproduction. Though asexual reproduction is faster and more energy efficient, sexual reproduction better promotes genetic diversity through new combinations of alleles during meiosis and fertilization.
Why is reproduction so important?
Reproduction is an important characteristic feature of living organisms. It is an essential life process which not only helps in survival but also helps in continuity of that race and group immortality, as by reproduction. … Reproduction also helps in increasing the population of the species.

What is 12th reproduction?
Reproduction is defined as a biological process in which an organism gives rise to young ones (offspring) similar to itself. The offspring grow, mature and in turn produce new offspring. Thus, there is a cycle of birth, growth and death. Reproduction enables the continuity of the species, generation after generation.
What is called female sperm?
They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome. These reproductive cells are produced through a type of cell division called meiosis.
What are the 3 female hormones?
In females, the ovaries and adrenal glands are the main producers of sex hormones. Female sex hormones include estrogen, progesterone, and small quantities of testosterone.

How are sperms produced?
The testes are responsible for making testosterone, the primary male sex hormone, and for producing sperm. Within the testes are coiled masses of tubes called seminiferous tubules. These tubules are responsible for producing the sperm cells through a process called spermatogenesis.
What is the main function of reproduction Class 11?
Reproduction is a complex process and is a characteristic feature of all living entities. It is a biological process which is carried out to produce a new offspring which requires the involvement of the male and female gametes.
Can humans reproduce asexually?
Asexual reproduction in humans is carried out without the immediate use of fertilization of the male and female sex cells (the sperm and egg). … However, there is a mode of asexual reproduction which occurs naturally in a woman’s body which is known as the monozygotic twinning.
What happens during reproduction?
In the reproductive process, a male sperm and a female egg provide the information required to produce another human being. Conception occurs when these cells join as the egg is fertilized. Pregnancy begins once the fertilized egg implants in the uterus.
What are the 4 steps of fertilization?
asymmetric and motile sperm cell and a large and nonmotile egg. 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.
Why is human reproduction important?
