Unicellular vs Multicellular Growth

Giant African Millipedes just like all multi celled organisms consists of cell organelles, cells, tissues, organs and organ systems that all work together in order to give life to the specific organism.

The giant African millipede is one of the largest species growing up to 32cm in body length. The body compromises of around 30-40 segments with four legs per segment equaling around 400 legs per millipede. In order to grow they must shed their exoskeleton and as they do this they grow additional body segments with legs. Their life expectancy is roughly around 10 years, typically living longer if living in captivity.

Uni-celled organisms (Fuligo septica) can use mitosis as a type of asexual reproduction in order to replicate identical copies of themselves and expand there colony. However, multicellular organisms  such as Archispirostreptus gigas use the process of mitosis to produce more cells for growth and repair. Due to uni-celled organisms simplistic life form, they can exist in areas that are classed as dangerous or not ideal to multi celled organisms and can be highly acidic or radioactive, but on the other hand, the downside of the fuligo septica is when faced with undesirable conditions they can be easily wiped out due to all cells being clones of one another. This means that they also lack genetic diversity which makes them vulnerable to the same threats such as temperature change and/or ph change. This however isn’t the case for multi celled organisms (Archispirostreptus gigas) they don’t reproduce in the process of mitosis. Multi celled organisms use this process to grow in size and contain specialised and differentiated cell types that all function accordingly in order to maintain life for the organism. (BBC Bitesize, 2020)
