How many cells are in a slug
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… Web1 day ago · Fallen NRL star Jarryd Hayne has begun a brutal new existence as a maximum security prison inmate being strip searched and locked into a tiny cell.

Researchers found that a certain species of sea slug, Elysia chlorotica, has in its genome a gene for repairing and maintaining chloroplasts. The gene is identical to one found in the algae from which the slugs steal chloroplasts for performing photosynthesis during periods of dietary shortfall.
WebEach slug contains a single nucleus. The slugs crawl through dung, soil, rotting mushrooms, decaying leaves and other organic material at an average speed of 1 mm per hour. When conditions are right, all the slugs in an area join together to create a pseudoplasmodium, a "fake plasmodium". WebWhen food is depleted, cellular slime molds aggregate into a mass of cells that behaves as a single unit, called a slug. Some cells in the slug contribute to a 2–3-millimeter stalk, drying up and dying in the process. Cells atop the stalk form an asexual fruiting body that contains haploid spores (Figure 7).
