The intense magenta color indicates intense positive staining in this multicellular aggregate.
Adaptations to environmental extremes by multicellular organisms tubes create more homogeneous chemical and thermal microniches and likely play a role in microbial diversity.
Once formed at a cold temperature, the multicellular structures were stable at room temperatures despite agitation of the culture for 1 day.
Like the tardigrades, the rotifers are multicellular animals.
In multicellular organisms, body size has two components : cell size and cell number.
That issue is defining the spatially and temporally restricted processes that must occur for a fertilised oocyte to transform into a multicellular organism.
This contrasts with most other multicellular plant systems, including the angiosperms, where fertilisation occurs deep within the maternal tissue.
The mechanism responsible for the destruction of the secretory epithelium is apoptosis, a form of programmed cell death that occurs in all multicellular animals.
