|What happens when a plant does not get enough water?|
|Question Date: 2015-01-13|
All living things need to water to survive.
This is because all living things are mostly made
of water and since they lose water in different
ways, they need to get more water to stay the same
size. So if a plant does not get enough water, it
will shrink. If it goes long enough without water
it will die because the plant uses water for a lot
of different jobs needed to keep the plant alive.
Water is the single most important thing for
living things. Humans, animals and plants are
composed mostly out of water and absolutely need
it to grow and thrive. Plants need nutrients
from the soil, water, and light from the sun to
grow and stay alive. If plants did not get water,
they would die. How much water each plant
needs depends on what plant it is. Something like
a cactus or a plant in the dessert does not
require as much water as a plant which grows in
the rainforest. The two main things plants need
water for are turgor, to keep the upright and make
sure it doesn't wilt and for photosynthesis.
Plants need water, just like we and other
animals do. If we don't have water, we get
dried out. If we get too dried out, we die. The
same is true for plants, but plants' seeds can
live for a long time even if they are quite dry.
I found a scientific paper that says we are
just starting to understand what happens to plants
when they get dry, before they die.
When plants are making seeds, the last stage is
for the seeds to lose lots of water. That's good
for the seeds, because they would get moldy if
they were too wet. The seeds can stay very dry
for a long time without dying.
The plant can no longer get nutrients up from the
roots, so the plant dies.
Short answer…it dies. But let's explore
that process in a little more detail:
Water is needed for photosynthesis, the process
by which a plant uses sunlight to turn water and
carbon dioxide into energy! The byproduct of this
process, lucky for us, is oxygen. Water also keeps
the plant rigid. You may have noticed that when
your houseplants are not watered they start to
droop and look pretty unhappy. They perk up
incredibly quickly when you give them something to
