Great questions! The sun helps plants grow by
providing energy for the process of photosynthesis
to occur. Photosynthesis is the way plants
convert inorganic resources, such as sunlight,
water, carbon dioxide, and minerals, into organic
resources that the plant can use.
The sun helps humans in several ways!
First of all, it is a source of warmth,
which allows human bodies to function. Without the
warmth of the sun, the surface of the planet would
be very cold, and the various cells, tissues, and
organs in our body would cease to function.
Furthermore, recall that the sun facilitates
photosynthesis. One of the by-products of
photosynthesis is oxygen, which is necessary for
humans to breathe and live. Another way that the
sun is important is that it helps to warm the
oceans, which after many steps eventually results
in the weather patterns we see.
As for your last question, the sun HAS solar
energy. The word solar means "of, related to, or
determined by the sun" (online dictionary). It
turns out that light from the sun carries energy.
This includes the visible light (light we can see
from our eye) and also the light we cannot see
from the sun's spectrum!
The sun gives us energy in its light rays -- think
of the heat you feel when you sit in the sunshine
(or get a sun burn). Heat is a type of energy.
Plants use the energy in sunlight to grow. Plants
use the energy from the sun instead of eating,
like we do. This process plants use to make
energy from sunlight is called photosynthesis.
Humans eat plants, so we indirectly use the sun's
energy by eating plants which have used the
sunlight to grow. We also use sunlight to get our
vitamin D -- we need enough hours in the sun's
energy or we don't get enough vitamin D!
The sun is the source of most of the energy on
the Earth's surface (what isn't from the sun
comes from volcanoes). The sun is needed for plant
growth, and its warmth is what keeps the Earth
from turning into a frozen ball of ice. The sun's
energy also is what powers all of our weather, and
we need the rain and snow for life on land to
The sun provides energy through light
radiation. This helps plants by providing them
with the energy to convert carbon dioxide into
sugars, which is how they grow.
The sun helps humans in a variety of ways, but
most importantly by fueling plant growth, so we
can eat the plants and the other animals that eat
The sun helps solar energy in two ways. There are
solar cells, also called photovoltaics, which
convert light energy into electricity. There are
also thermal solar systems, which capture the
warmth of the sun and convert the heat energy into
