    Can someone please explain plant cloning?

    Okay so the first way is by taking plant cuttings. This is when a branch from a plant is cut off and the stem is planted in compost. Plant hormones are used to encourage on the cutting so that new roots can develop. It is usually covered in a clear plastic bag to keep it moist and warm. After a few weeks new roots develop and a new plant is produced which is identical to the parent plant.

    The second way is by using tissue culture. This is when you take tissue samples from the plant and place it in sterile agar jell with plant hormones and lots of nutrients. The tiny plantlets are then transferred into potting trays where they develop into plants. It is more expensive but you can produce much more at one time compared to plant cuttings.

    Theres also animal somatic cell cloning, where nucleus of a normal diploid cell is extracted and injected into an enucleated (cell with nucleus removed) egg cell. An electric shock (or some other stimulus) is applied which stimulates the cell to start division. This is then implanted into the uterus of a mammal (a surrogate mother) and allowed to develop like any other freshly fertilised egg.
