In Multiple Fission:
In multiple fission, spores are formed inside a cyst. This process is commonly observed in certain protozoans and algae. Multiple fission is a form of asexual reproduction where a single parent organism divides into multiple daughter cells.

Process of Multiple Fission:
1. Cyst Formation: The parent organism develops a protective cyst around itself.
2. Nucleus Division: The nucleus of the parent organism undergoes several rounds of division, resulting in the formation of multiple nuclei.
3. Cytoplasm Division: The cytoplasm of the parent organism also divides multiple times, segregating the nuclei into separate compartments.
4. Spore Formation: Each compartment containing a nucleus and a portion of cytoplasm develops into a spore.
5. Release: The cyst ruptures, releasing the spores into the environment.
6. Germination: The spores germinate under favorable conditions, giving rise to new individual organisms.

In Spore Formation:
Spore formation, also known as sporogenesis, is a process of reproductive cell formation that occurs in various organisms including fungi, bacteria, and plants. Spores are specialized reproductive cells that can give rise to new individuals under suitable conditions.

Process of Spore Formation:
1. Sporocyte Development: The parent organism produces specialized cells called sporocytes, which undergo differentiation to form spores.
2. Spore Development: The sporocytes undergo mitotic divisions to produce haploid spores.
3. Spore Maturation: The spores mature and develop protective structures such as cell walls, enabling them to withstand harsh conditions.
4. Spore Release: The mature spores are released into the environment either through active expulsion or by passive means like wind, water, or animal dispersion.
5. Germination: When the spores encounter suitable conditions, they germinate and give rise to new individual organisms.

Differences between Multiple Fission and Spore Formation:
1. Organisms: Multiple fission is observed in certain protozoans and algae, while spore formation occurs in various organisms including fungi, bacteria, and plants.
2. Process: Multiple fission involves the division of a single parent organism into multiple daughter cells, whereas spore formation involves the development and maturation of specialized reproductive cells (spores).
3. Protective Structures: In multiple fission, a cyst is formed around the parent organism, providing protection. In spore formation, the spores themselves develop protective structures such as cell walls.
4. Genetic Material: Multiple fission results in the distribution of multiple nuclei into separate compartments, whereas spore formation involves the development of haploid spores containing the genetic material for the next generation.
5. Release Mechanism: In multiple fission, the cyst ruptures to release the spores. In spore formation, the mature spores are released by active expulsion or passive dispersion.
6. Germination: In multiple fission, the spores germinate to give rise to new individuals. In spore formation, the spores themselves germinate to develop into new organisms.

Overall, multiple fission and spore formation are two different processes of reproduction, each with its own unique characteristics and mechanisms.

Multiple fission occurs in unicellular organisms whereas spore formation occurs in simple multi-cellular organisms.
Example of organism showing multiple fission is Plasmodium whereas Rhizopus shows spore formation.
In multiple fission, the nucleus of the parent cell undergoes repeated divisions to produce many daughter nuclei. The cytoplasm also divides and cleaves around each nucleus forming several daughter cells in the parent cell.
Organisms like Rhizopus produces spores in reproductive structures called sporangia. Each spore has a thick wall to protect it. The spore germinates to produce a new organism.
