Solution

a) Oviparous animals give birth to young ones - (F)
No, viviparous animals give birth to young ones.

(b) Each sperm is a single cell - (T)
Sperm cells are gametes, and thus, they are unicellular

(c) External fertilization takes place in frog - (T)
The female frog releases many egg cells in the water. As the egg cells come out of the female, the male frog releases sperm cells over them. Fertilization takes place. Fertilization in frogs takes place outside the body of the female frog in the water.
(d) A new human individual develops from a cell called as gamete - (F)
No, a new human individual develops from combination of two gametes called as zygote.

(e) Egg laid after fertilization is made up of a single cell - (T)
After fertilization zygote is formed which is single cell.

(f) Amoeba reproduces by budding - (F)
No, amoeba reproduces by binary fission.

(g) Fertilization is necessary even in asexual reproduction - (F)
In asexual reproduction, a single organism or cell makes a copy of itself without fertilization.

(h) Binary fission is a result of asexual reproduction - (T)
Binary fission is the process of splitting of a parent cell into two daughter cell without fertilization.

(i) A zygote is formed as a result of fertilization - (T)
Zygote is formed by fertilization of male and female gamete.

(j) An embryo is made up of a single cell - (F)
No, an embryo is now made up of three layers ectoderm, mesoderm, and endoderm.
