Indicate whether the following statements are true (T) or false (F).

Explanation-

(a) Each sperm is a single cell- True

Sperm is a male gamete and it is formed after the cell division process (meiosis), each sperm is a single cell.

(bExternal fertilization takes place in a frog- True

The female frog releases its egg outside in the water and then the male frog releases its sperm outside in the water, then fertilization takes place in the water. Hence, fertilization is outside the body.

(c ) Egg laid after fertilization is made up of a single cell- True

The fertilized egg is only a single cell

( d) Amoeba reproduces by budding- False

Amoeba reproduces by binary fission in normal conditions, under unfavorable conditions amoeba reproduce through multiple fission.

(e) Fertilization is necessary even in asexual reproduction- False

In asexual reproduction, only a single cell or single individual is needed, so fertilization is not necessary for asexual reproduction.

(f) Binary fission is a method of asexual reproduction- True

In binary fission only a single cell is involved so, binary fission is a type of asexual reproduction seen in yeast. 

(g) A zygote is formed as a result of fertilization-True

 A gamete is a single cell when male gamete sperm and female gamete egg is fused together it forms a zygote.

(h) An embryo is made up of a single cell- False

The embryo is formed when the zygote undergoes multiple divisions, so the embryo is made up of multiple cells.

Final Answer-

(a)Each sperm is a single cell- True
(b)External fertilization takes place in a frog- True
(c)Egg laid after fertilization is made up of a single cell- True
(d)Amoeba reproduces by budding-False
(e) Fertilization is necessary even in asexual reproduction- False
(f) Binary fission is a method of asexual reproduction- True
(g) A zygote is formed as a result of fertilization-True
(h) An embryo is made up of a single cell- False
