Answer:
Cell fusion does not occur with bacterial cells and these cells are likely undergoing conjugation.
Explanation:
Conjugation is defined as mating of two bacterial cells during which DNA is transferred from donor to recipient cell. The mating process is controlled by an F (Fertility) plasmid (F factor). Pilin protien forms a sex pilus (conjugation tube) .
Pilus of the donor male bacterium carrying the F factor (F+) attaches to a receptor on the surface of the recipient's female bacterium which doesn't contain F factor. The cells are then withdrawn into direct contact by reeling in the pilus.
