Solved by a verified expert:Mitosis provides asexual reproduction in most unicellular eukaryotes. Multicellular eukaryotesbecome multicellular via this process, and many multicellular species are capable of asexualreproduction, producing "clones" of the parent plant, fungus, or animal. DNA provides the"blueprint" for cellular structure & function.An interesting "environmental" change occurs during development – identical cells, by virtue oftheir position in a forming embryo (plant OR animal) & their interactions with neighboring cellsbecome "tissues". Each tissue is specialized for function; while the nucleus contains all thegenes of the entire organism, a tissue cell will only express (use) a subset of those genes. Forinstance, only plant leaves make mesophyll cells that contain abundant chloroplasts forphotosynthesis, and only mammalian red blood cells make hemoglobin to carry oxygen. Ourbodies are tiny ecosystems, with each type of cell doing its part to enhance our survival!Thinking of the ecosystem as an organism – what specialized DNA-environment interactions arerequired to complete a food web? How is asexual reproduction advantageous to productivity &recycling nutrients/raw materials? What other connections do you see?
