WebJun 23, 2024 · The term gametic refers to the fact that gametes are the result of meiosis. During the gametic life cycle a reproductive cell produces haploid gametes (sex cells such as egg and sperm) that combine to produce a zygote. The zygote grows by cell division and cell elongation to produce a multicellular diploid individual. WebGametic cells respond to antibody presentation very differently from vegetative cells, mobilizing even high concentrations of antibody towards the flagellar tips; the possibility is discussed that such "tipping" ability reflects a differentiated gametic property relevant to sexual agglutinability. Gametic cells also respond to antibody ...
