Thus Weismann came to make a distinction between the mortal (somatic) cells and the immortal (germ) cells of multicellular organisms.
Multicellular organisms, on the other hand, must perish after a definite duration of life, and so are mortal.
For the germ-plasm he believes to have had its origin in the unicellular organisms, and to have been handed down from them in one continuous stream through all successive generations of multicellular organisms.
In multicellular organisms, this single originating cell is usually formed by the fusion of two imperfect cells by what is indifferently called conjugation, sexual reproduction, or ‘amphimixis.
Multicellular organisms of more or less elaborate structure plainly cannot, without breaking up, fuse together like single cells.
Sexual reproduction is so universal in all classes of multicellular organisms, and nature deviates so rarely from it, that it must necessarily be of pre-eminent importance.
The above list will hopefully provide you with a few useful examples demonstrating the appropriate usage of "multicellular organisms" in a variety of sentences. We hope that you will now be able to make sentences using this group of words.
