Indicate whether the following statements are True (T) or False (F):
(a) Oviparous animals give birth to young ones. ( )
(b) Each sperm is a single cell. ( )
(c) External fertilization takes place in frog. ( )
(d) A new human individual develops from a cell called gamete. ( )
(e) Egg laid after fertilization is made up of a single cell. ( )
(f) Amoeba reproduces by budding. ( )
(g) Fertilization is necessary even in asexual reproduction. ( )
(h) Binary fission is a method of asexual reproduction. ( )
(i) A zygote is formed as a result of fertilization. ( )
(j) An embryo is made up of a single cell. ( )
(a) False
This statement is false because oviparous animals lay eggs and viviparous animals give birth to young ones.
(b) True
This statement is true because each sperm is a single cell and an egg is also a single cell.
(c) True
External fertilization takes place outside the female body; they lay eggs and then eggs got hatch and young ones are produced. So, this statement is true that external fertilization takes place in frogs.
(d) False
This statement is false because a new human individual develops not from a cell called gamete. A new individual is formed due to the fusion of two single cells i.e. sperm and egg.
(e) True
Yes, this statement is true because egg is a single cell.
(f) False
This statement is false because amoeba reproduce by binary fission. It is a type of asexual reproduction.
(g) False
This statement is false because fertilization only occurs in sexual reproduction, not in asexual reproduction.
(h) True
This statement is true because asexual reproduction is that in which only single parent is involved. Binary fission, budding are the types of asexual reproduction.
(i) True
Fusion of male and female gamete occurs and forms an zygote. This process of fusion is known as fertilization.
(j) False
This statement is false because embryo is formed by the repeated divisions of zygote or we can say that embryo is the mature zygote.
