Plants Importance For Health
Plants are the basis of the food pyramid for all living things, even other
plants. They have always been very important to people, not only for
food, but also for clothing, weapons, tools, dyes, medicines, shelter and a
great many other purposes. Both humans and animals benefit from plants. We eat
many different types of plants such as fruits and vegetables. We also use plants
for our herbs. Plants are also used to manufacture many different products such
as shampoos, rubber, paper, and camera film. In some countries, fermented sugar
cane is used instead of gasoline. Animals use plants in many different ways
also. They eat many fruits and other plants. Many animals use plants for
shelter. Plants also provide animals with protection from predators. The
destruction of different plants sometimes leads to animals becoming endangered
or extinct. The basic structure of plants consists of roots, stem, leaves,
flower and/or fruit or seeds. A flower is the part of the plant that makes the
seeds. The main parts of a flower are the carpels and stamens. These parts are
often found in the center of the flower. There are egg cells in the carpel and
pollen cells in the stamen. All flowers have four basic parts: sepals, petals,
carpels, and stamen. Different flowers have different numbers and shapes of
these parts. Most plants can be divided into one of two general categories:
herbaceous or woody plants. Herbaceous plants have soft stems, while woody
plants are tree-like. Herbaceous plants produce completely new stems each year.
The approaching cold weather causes the new stems to die back to the ground.
Some herbaceous plants survive periods of cold by forming underground bulbs, or
tubers used for food storage. Many herbaceous plants complete their life cycles
within one growing season and the whole plant dies, even the roots. These
annuals produce seeds that will form new plants the next year.Land plants are
divided into two groups based on whether they have vascular tissues or not. All
nonvascular plants are placed in one division. There are nine divisions of
vascular plants. These are divided based on whether they form seeds or not.
