| Where do plants grow bigger, in soil or in water?|
|Question Date: 2014-01-09|
There are various types of plants, land and
aquatic. For the most part, plants grow better
(which is what I think you mean by bigger, because
all plants are different sizes) in soil. Plants
need sunlight, water, nutrients from the soil, and
air to grow the best. When they are just in water,
they aren't exposed to as much sunlight as they
would be if they were on land in soil, they don't
get as much air, and they don't get the nutrients
from the soil. Plants do grow in water, but they
grow the best planted on land in soil where they
can get soil, sunlight, water, and air.
In general, plants need more than just water to
grow big and healthy, although water is a good
start, and seeds can usually be "germinated" with
just water. Germinating is getting the seed to
sprout. You can try this at home by putting a seed
in a ziplock pouch with a moist paper towel and
placing it in the dark. Most seeds will germinate
in a few days if they are fresh.
After the seeds are sprouted, you usually want
to put the sprouts in soil because soil provides
additional nutrients. Most plants prefer a certain
chemical environment to thrive. There is an entire
field called soil science that involves a lot of
chemistry and is extremely important for
There is a type of agriculture that is
soil-free, and that is called "hydroponics." In
hydroponics, the plants are mostly grown in water,
however nutrients and minerals are added to the
water to ensure that the plants can grow healthy.
That's a tricky question. Plants need 3 basic
things to grow: Sunlight, water and nutrients.
Without one of these, the plant will not survive.
Plants can be grown in water (without soil), but
only if we add nutrients to the water
(fertilizer). If it was pure water, then the
plants would not survive. If you tried to grow a
plant in soil without water, then the plant would
not survive also. So basically, if you give plants
unlimited water, light and nutrients then they
will grow best. Different plants have different
requirements, but that is the general formula.
