difficult one to observe‚ for three main reasons.

Observation of Mitosis Introduction: Reproduction is the biological process by which new individual organisms are produced.

Sexual reproduction is creation of offspring by fusion of male gametes (sperm) and female gametes (eggs) to form zygotes. Asexual reproduction involves a type of cell division known as mitosis. Mitosis is the scientific
