Solution:
Fission, budding, and other processes are some of the numerous ways that unicellular organisms reproduce. In this circumstance, the cell divides into two daughter cells, and the cell-division process continues.
However, in multicellular organisms, the organ system for reproduction is different. Multicellular organisms can reproduce in a variety of ways, including vegetative growth and spore generation.
Sexual reproduction is the primary method of reproduction in more complex organisms like humans and animals.
