Assertion (A): Amoeba reproduces by fission. Reason (R): All unicellular organisms reproduce by asexual methods.
✓ Correct answer: a) Both A and R are individually true and R is the correct explanation of A
ExplanationReproduction is the process by which organisms produce offspring.It ensures the continuation of a species.There are two main modes of reproduction: Asexual Reproduction involves a single parent and produces offspring that are genetically identical to the parent.Examples include binary fission (in bacteria), budding (in yeast), and parthenogenesis (in some insects).Sexual Reproduction involves two parents (usually of different sexes) and combines genetic material from both parents to create offspring with unique genetic variations.Examples include fertilization in animals and pollination in plants.Assertion A is True: Amoeba, a unicellular protozoan reproduces asexually through binary fission, a process where the parent cell divides into two genetically identical daughter cells.Process of Binary Fission in Amoeba: Growth Phase: The Amoeba increases in size, accumulating nutrients required for division.Nuclear Division (Mitosis): The nucleus undergoes mitotic division, ensuring that both daughter cells receive an identical set of genetic material.Cytoplasmic Division: The cyto
