WebIf an organism could be grown on an agar plate or in a liquid culture, then it could be studied, analyzed, and added to our growing catalog of prokaryotic species and strains. Some prokaryotes, however, can't grow in a laboratory setting (at least, not under the conditions scientists have tried). Webmulticellular male gametophytes The gametophyte is the dominant generation in mosses. While walking in the woods, you come across some low-growing plants clustered at the base of a tree. You collect one as a specimen for biology class. Upon examination in the lab, you find that the leaf-, stem-, and root-like structures contain no vascular tissue.

Multicellularity allows an organism to exceed the size limits normally imposed by diffusion: single cells with increased size have a decreased surface-to-volume ratio and have difficulty absorbing sufficient nutrients and transporting them throughout the cell. Multicellular organisms thus have the competitive advantages of an increase in size without its limitations. They can have longer lifespans as they can continue living when individual cells die.
