mereorganisme

Mereorganisme refers to a class of organisms that lack true tissues and organs. This means their cells are not organized into specialized, differentiated tissues like those found in more complex life forms. Instead, their bodies are typically composed of loosely aggregated cells that perform various functions, often with a degree of independence. Examples of mereorganisme include sponges and some types of colonial protozoa. These organisms often exhibit simple body plans and rely on diffusion for nutrient and gas exchange. Their cellular organization allows for a high degree of regeneration, as individual cells can often divide and differentiate to replace lost or damaged parts. Reproduction can occur both asexually, through budding or fragmentation, and sexually. The study of mereorganisme provides insights into the early evolution of multicellularity and the fundamental processes of cellular organization and differentiation. They represent a transitional stage between unicellular and multicellular life.
