Rhizopus Rhizopus Rhizopus is a genus of common saprophytic fungi on plants and specialized parasites on animals. They are found on a wide variety of organic substrates, including "mature fruits and vegetables", jellies, syrups, leather, bread, peanuts, and tobacco. They are multicellular. Some "Rhizopus" species are opportunistic agents of human zygomycosis (fungal infection) and can be fatal. "Rhizopus" infections may also be a complication of diabetic ketoacidosis. This widespread genus includes at least eight species. "Rhizopus" species grow as filamentous, branching hyphae that generally lack cross-walls (i.e., they are coenocytic). They reproduce by forming asexual and sexual spores. In asexual reproduction,
Deep chlorophyll maximum of phytoplankton that have adapted to functioning in low light conditions. To adapt to low light conditions, some phytoplankton populations have been found to have increased amounts of chlorophyll counts per cell, which contributes to the formation of the DCM. Rather than an increase of overall cell numbers, seasonal light limitation or low irradiance levels can raise the individual cellular chlorophyll content. As depth increases within the mixing zone, phytoplankton must rely on having higher pigment counts (chlorophyll) to capture photic energy. Due to the higher concentration of chlorophyll in the phtoplankton present, the DCM does not predict the depth
