Answer 1

There are different types of asexual reproduction. Some of them are budding, binary fission, gemmules formation, vegetative reproduction, etc.

Complete answer:
Reproduction is characterized as a biological process in which the individual gives birth to the offspring identical to themselves. The offspring develops, matures, and creates new offspring. There is, thus, a sequence of life, rise, and death. Reproduction causes the population to live, generation after generation. The ecosystem of the cell, its internal morphology, and many other variables are generally responsible for how it reproduces. It is of two kinds, depending on whether one or two species engage in the reproductive process. When the offspring is produced by a single parent with or without the presence of a gamete, the reproduction is asexual. When two opposite sex involves in the reproductive process and requires the fusion of female and male gametes, it is known as sexual reproduction.

(a) Oviparous animals give birth to young ones. (F)
Viviparous animals give birth to young ones. Oviparous animals lay eggs.
(b) Each sperm is a single cell. (T)
Sperms are produced by the testes in the male reproductive organs. A sperm is a single cell.
(c) External fertilization takes place in frogs. (T)
External fertilization is a type of fertilization where fertilization takes place outside the female body. This type of fertilization is mostly seen in aquatic animals like fish, frog, etc.
(d) A new human individual develops from a cell called gamete. (F)
The development of a new individual from a cell called zygote. During the fertilization in humans, a single nucleus is formed by the fusion of the egg and the sperm. This results in the zygote formation.
(e) Eggs laid after fertilization are made up of a single cell. (T)
During the fertilization in humans, a single nucleus is formed by the fusion of the egg and the sperm and the egg. This results in the zygote formation. Zygote is a single cell.
(f) Amoeba reproduces by budding. (F)
Amoeba reproduces by binary fission. Binary fission is a type of asexual reproduction where two daughter cells are produced from a single mother cell.
(g) Fertilization is necessary even in asexual reproduction. (F)
In the case of asexual reproduction, a single parent cell is able to produce offspring. As a consequence, the young ones that are created are similar to one another and they are also the exact clones of their parents. Fertilization is not necessary in asexual reproduction.
(h) Binary fission is a method of asexual reproduction. (T)
Binary fission is a type of asexual reproduction where two daughter cells are produced from a single mother cell. This type of asexual reproduction can be seen only in unicellular organisms. Like amoeba, bacteria can also reproduce through binary fission.
(i) A zygote is formed as a result of fertilization. (T)
During the fertilization in humans, a single nucleus is formed by the fusion of the sperm and the egg. This results in the formation of zygote. Zygote is a single cell.
(j) An embryo is made up of a single cell. (F)
After fertilization, the zygote develops to the embryo. Embryo is a developing structure with three layers. An embryo is not made up of a single cell.

Note: When the offspring is produced by a single parent with or without the presence of a gamete, the reproduction is asexual. When two opposite sex involves in the reproductive process and requires the fusion of female and male gametes, it is known as sexual reproduction.
