Question

Bacteria lack alternation of generation because
there is
(a) neither syngamy nor reduction division
(b) distinct chromosomes are absent
(c) no conjugation
(d) no exchange of genetic material

Answer 1

Bacteria lack alternation of generation because there is neither syngamy nor reduction division.

• Option (a) is correct.
• Asexual reproduction takes place in bacteria instead of sexual reproduction (involving the formation of gametes, their fusion and meiosis).  
• The transfer of genetic material from a  donor to a receptor takes place using methods like conjugation, transduction and transformation (but does not result in multiplication of cells).

Answer 2

Bacteria lack alternation of generation because  there is neither syngamy nor reduction division.

Option (A) is correct.

Explanation:

• In sexual reproduction, syngamy and meiotic division takes place.
• But in bacteria, during sexual reproduction there is no formation of gametes.
• Hence no syngamy and reduction division occurs.
• Bacteria lack alternation of generation.
• Conjugation and exchange of genetic material takes place in bacteria.

Thus Bacteria lack alternation of generation because  there is neither syngamy nor reduction division.
