Gnoma [55]

Double fertilization-plants with seeds (flowering plants), two male gametes joining with female gametophyte

Gametophyte generation-both (haploid, sexual stage stage-gametophyte, and the diploid stage that produces spores – sporophyte)

Endosperm formed-plants with seed because it is a tissue formed inside the seed which surrounds the embryo and provides nutrition

Mitosis-both (mitosis occurres in spores)

Therefore the yellow ring inside the bacterial cell will disappear by step 3 after which the nucleic acid is injected into the host cell by the virus .

Hence we can conclude that the bacterial DNA structure will disappear because of the usage of the ribosomes by the nucleic acid from the virus
