VEGETATIVE This is reproduction in plants and fungi, by one parent, in what is known as asexual reproduction (unlike sexual reproduction). It can occur by the development of a plant's stem, leaf or root, rather than flower and seed growth. Part of a plant's body can grow into a new individual, for example bulbs, corms, tubers and rhizomes are all parts of certain plants which can grow into new plants. It can also occur when fungi produce asexual spores.   Click on Back in your browser to return to previous page.             WEED The word "weed" is used to describe any plant found growing where it is not wanted.     Click on Back in your browser to return to previous page.
