  • Asexual Reproduction - 803 Words
    Asexual Reproduction Samantha Ramroop Asexual Reproduction Asexual reproduction is a form of reproduction that requires only one parent, with no exchange of genetic material and fertilization. A number of organisms use this method to perpetuate themselves. Some species are capable of both asexual and sexual reproduction, alternating methods depending on environmental factors. Most organisms that reproduce asexually are single celled, with the exception of...

    Gametes are sex cells. Fertilisation is when half the genetic material comes from male gamete and half come from female gamete and they fuse together to form a zygote. Zygote is a fertilized egg. Embryo is a divided zygote. Binary Fission in Bacteria Bacteria are microscopic organisms made up of one cell and they do not have a nucleus but a loop of DNA. When bacteria, reproduce asexually the DNA loop is copied so that there is some for each new cell. The bacterial cell deivides into two...

  • Cellular Reproduction - 512 Words
    Cellular Reproduction Cellular Reproduction is the process by which all living things produce new organisms similar or identical to themselves. This has to happen because if a species were not able to reproduce, that species would quickly become extinct. Reproduction consists of a basic pattern: the conversion by a parent organism of raw materials into offspring or cells that will later develop into offspring. The reproductive process, whether asexual or sexual always involves an...

  • Plant Reproduction - 756 Words
    Plants have two different ways to reproduce. The first one is vegetative reproduction. With this type all the plants that have the same parent have the same genetic make-up. This also lets plants pass adaptations on that they have abtained over the years. Plants with good genetic make-up usually spread quickly and take over an area. An example of this would be the dandelion. These plants can sprout from any part of the plant. An example of this is the potato, farmers will pick the potatoes and...

  • A Sexual Reproduction - 1452 Words
    ASEXUAL REPRODUCTION Asexual reproduction is a mode of reproduction by which offspring arise from a single parent, and inherit the genes of that parent only; it is reproduction which does not involve meiosis, ploidy reduction, or fertilization. The offspring will be exact genetic copies of the parent. A more stringent definition is agamogenesis which is reproduction without the fusion of gametes. Asexual reproduction is the primary form of reproduction for single-celled organisms such as the...

    o Asexual reproduction Asexual reproduction involves only one parent individual, be in plant or animal. Asexual reproduction has many advantages. It is safe, certain (there are no problems of finding a receptive mate) and can give rise to large numbers of offspring very rapidly. The offspring produces are almost all genetically identical to the parent organism, and so a successful genetic combination can be passed on without change. This is an important advantage of asexual reproduction until...
