Most single-celled organisms reproduce through what reproduction?
Most single-celled organisms reproduce through asexual reproduction. Some plants, fungi and bacteria reproduce in this way. In asexual reproduction, the offspring inherit the genes of only one parent.
It depends on other factors.The most defining of which is the Prokarytoic or Eukaryotic classification of the organism. Some prokaryotes reproduce through budding and other forms of reproduction that greatly differs from the reproduction styles of multi-cellular organisms. But Eukaryotes reproduce through mitosis or meiosis even if they are single celled or multi-cellular.
Yes, but it depends on what you mean by cell division. One of the traits of an organism is that it can reproduce, either by asexual or sexual means. Bacterias use binary fission which divides itself into two, which is asexual reproduction. A larger, multicellular organisms often use sexual reproduction to reproduce and has cells that can go through cell division.
Sure they can. I'm sure you can think of lots of examples for asexual reproduction in single celled organisms (like an amoeboid, for instance.) The first example of a multicellular organism that comes to mind is the hydra, a small fresh water animal that reproduces through binary fission. There are lots of "types" of asexual reproduction, such as binary fission, budding, fragmentation, and through spores that multi-cellular creatures can go through.
Spores. Fungi reproduce sexually and asexually. The types of asexual reproduction are budding, fission, fragmentation, and sporulation. In reproduction through spores there is asexual created through mitosis and sexual created through meiosis. Asexual spore reproduction is dominant where haploid sporangiospores and conidiospores are created. Sexual fungal zygotes are only created when the fungi is under stressful conditions.
In sexual reproduction, two parents donate genes to their young, resulting in offspring with a mix of inherited genes. These genes are donated through a process called fertilization. There are two mechanisms by which fertilization can take place. The first is external (the eggs are fertilized outside of the body), and the second is internal (the eggs are fertilized within the female reproductive tract). While fertilization is necessary for organisms that reproduce sexually, individuals that…
Describe how natural selection might have caused differential reproduction among the ancestors of a fast swimming predatory fish such as the barracuda?
Natural selection is when biological organisms with favorable traits survive and reproduce more successfully than organisms that do not possess such traits. Organisms with negative or less useful traits survive and reproduce less successfully than organisms lacking such harmful traits. Natural selection played a huge part in the evolution of the great barracuda. The barracuda had to adapt their distinctive shape, design, and skills over the years and did so through many generations.
