How does a diatom reproduce
WebDiatoms reproduce asexually by cell division to produce two daugther cells by mitosis; each daughter cell receives one valve and it is reproduced by furrowing. The cell has vesicles … Webmortality, and nonviability of progeny. Here we test the hypothesis that observed detrimental effects of diatoms on the viability of copepod embryonic and naupliar stages (the diatom effect) are the primary reason for the observed patterns of reproduction and abundance. Furthermore, we test how assumptions about egg production
