WebThe diploid multicellular stage is called the _____ because it produces haploid spores by meiosis, each of which will give rise to a whole new gametophyte. Meiosis only occurs in diploid cells. 5. Animals produce three types of cell. These are diploid _____ (body) cells, and haploid sex cells or _____ (sperm and egg). One hypothesis for the origin of multicellularity is that a group of function-specific cells aggregated into a slug-like mass called a grex, which moved as a multicellular unit. This is essentially what slime molds do. Another hypothesis is that a primitive cell underwent nucleus division, thereby becoming a coenocyte. A membrane would then form around each nucleus (and the cellular space an…
