: : okay people could you guys please email it to me cause i dont really have time to check this again i am doing a science fair project and i need some information on how plants grow roots. Like why do they do it from cuttings and how? any info would be helpful thanks.
RICHIE: Plants grow roots to support or anchor the top of the plant and to provide a source
of nutients and water for growth. Roots grow from cuttings because plants have differenciated" cells....cells that have not made up their mind whether to be stems or roots. The growth of these particular cells is dependent on the
environment they are exposed to....light and air-they turn into buds, stems and leaves; if they
are put into very high humidity and warm temperatures with some media they produce
roots.
It is about that simple. Remember one thing....plants are always trying
to balance roots with top. If the top has no roots they immediately try to produce roots. Once the root system is there to produce more top, the top starts to grow. The roots must
grow to balance the new growth on the top and so on it goes.....year after year. If this
balance is interrupted along the way by us humans the plant is stressed but still tries
to satisfy this main theme.
Isn't it great that we have a creator God that made our environment so complex yet so simple.
