Difference between Plant and Animal Life cycle? Ans: Plant(more complex): Start off with a diploid (2 chromosome sets) after the young individual organism undergo meiosis and then we produce haploid (1n) spores then they undergo mitosis that produces a gametophyte (something that is multicellular). Male side we have pollen and female side we have an egg in haploid structure. 2n forms in zygote. Animals: 2n to n and there is meiosis that directly results in fromation of gemtes. What par...

absorptive heterotroph - An organism (usually a fungus) that obtains its food by secreting digestive enzymes into the environment to break down large food molecules, then absorbing the breakdown products. acidophile - able to live in extremely acidic environments adaptations - inherited aspects of an individual that allow it to outcompete other members of a population that lack the trait; evolve through natural selection Alfred Russel Wallace - came up with a mechanism for evolution simila...
