What do plants need?
Song-Plants need
Plants are living thing. Plants need air, soil, water, light and space to grow.
Plants need soil. Water and minerals are taken from the soil through
roots. Soil also provides support for the plant and an anchor for the
roots to grow in. Decaying plants and animals leave behind minerals in
the soil that are essential for future plant growth.
Plants need sunlight in order to grow properly. They use light energy to
change the materials - carbon dioxide and water into food substances
(sugars). This process of food productions is called photosynthesis.
Only in light can a green plant make food.
Plants most also have clean air. Green plants take in carbon dioxide
from air and use it during photosynthesis to make food. Dirty, smoggy
air blocks sunlight that plants must have.
Plants need water. Water is essential to all life on earth. No known
organism can exist without water. Plants use water to carry moisture and
nutrients from the roots to he leaves and food from the leaves back
down to the roots.
Plants must also have space in order to grow. Plants are found
everywhere -
deserts, mountains, arctic regions, forests, jungles, oceans, and even
in cracks of sidewalks of busy cities. If the space is small, the plants
will be small and stunted. Big plants need big spaces for their roots
and branches.
