Background Information
Plants are extremely important to life on Earth.
They grow on mountains, in valleys, in
deserts, in fresh and salt water—almost
everywhere on the planet. Plants come
in all shapes and sizes from the
smallest seedling to the towering
Giant Sequoias. Not only are plants
beautiful to look at, but they also
play a vital role in keeping people,
animals, and the Earth healthy.
Plants provide food, medicine, shelter, and
the oxygen we need to breathe. In fact,
everything we eat comes directly or indirectly
from plants. Herbivores (plant eaters) and
omnivores (animal and plant eaters) depend
of plants for survival. Even carnivores
(meat eaters) depend on plants because
they often prey on animals that eat plants.
Plants also provide shelter and habitats for
many animals.
Our precious soil also needs plants. When plants die they decompose
and provide topsoil that is rich in nutrients and helps seeds to germinate
and grow into seedlings. Plants also help to slow erosion because their
roots hold soil in place. When plants carry out photosynthesis, they
take in carbon dioxide from the atmosphere and release oxygen for us
to breathe.
The basic parts of most land plants are roots, stems, leaves, fowers,
fruits, and seeds. The function of each plant parts is described below.
` Roots anchor the plants in the soil and absorb nutrients and
water that are needed by the rest of the plant.
` Stems support the upper part of the plant and act as a transport
system for nutrients, water, sugar, and starches. Photosynthesis
can occur in the stem of some plants such as: cacti, celery,
asparagus, and bananas.
` Leaves are the parts of the plant where photosynthesis usually
occurs—where food for the plant is made. The green substance,
