Binary fission means division of a living cell into two daughter cells. After division of the parent cell two new daughter cells or we can say two new individuals are produced without the fusion of gametes means via asexual reproduction.
Spore formation is the mode of asexual reproduction in some organisms like fungi in which it gives rise to a globular structure known as sporangia, which contains spores. The sporangia burst to release spores and each of these spores germinates to produce a new individual without the fusion of gametes means via asexual reproduction.
In both types of reproduction, the individuals produced are clones of their parents.
