Asexual Reproduction of Flowering Plants
In vegetative growth, new roots and shoots grow right out of extensions or fragments of a parent
plant by way of mitosis. All offspring are genetically identical (unless mutation occurs).
Strawberry plants send out runners. Oranges come from trees that reproduce by parthenogenesis
(development of an embryo from an unfertilized egg).
In artificial propagation, houseplants such as African violets can be produced from cuttings of
shoot systems.
In tissue culture propagation, cultured bits of phloem can be induced under laboratory conditions
to form clumps of tissue that will give rise to roots. Tiny plant bits are grown in rotating flasks
containing a liquid growth medium.
