The reproduction process that involves a single organism is called:

  1. Parthenogenesis

  2. Spore formation

  3. Fertilization

  4. Budding

The correct answer is: Parthenogenesis

Parthenogenesis is a form of asexual reproduction in which an organism can produce offspring without the involvement of another individual. It does not involve the fusion of gametes and only requires one organism to be involved in the reproduction process. Option B, spore formation, is a type of asexual reproduction in which spores are produced and develop into new individuals. This process can involve multiple organisms. Option C, fertilization, is the fusion of two gametes (egg and sperm) to form a zygote, which develops into a new individual. This process requires the involvement of two organisms. Option D, budding, is a form of asexual reproduction in which a new organism develops as an outgrowth of the parent organism. It may appear to involve only one organism, but it requires the original organism to have sexually reproduced at some point in its life cycle. Therefore, the
