|How do plants interact with their environment?
Please give me an answer.|

I’m so happy to give you an answer to your
question! Plants interact with their
environment in lots of amazing ways! Plants
are able to sense light and grow towards it.
Have you ever noticed a plant by the window
growing towards sunlight?
This is actually called “phototropism”
and it means that plants respond to light.
phototropism Plants use light to make their
own food, so plants have adapted to be able to
detect light and move towards it.
Another “tropism” plants have is
gravitropism This is when plants sense
gravity and grow away from it (the opposite of
what they do to light). Why do plants grow
away from gravity? Well, light is usually up,
away from the pull of gravity, so this is just
another adaptation plants have to get closer to
the sunlight they need to make food. Have you
ever noticed that trees on the side of a mountain
still grow upwards (instead of sideways)?
That’s gravitropism! Even if there was
no light around, plants can still sense gravity
and grow away from it.
Another way plants interact with their environment
is by opening and closing holes on their
leaves, called stomates, in response to carbon
dioxide. Just like humans need oxygen to breath
in (and we breathe out carbon dioxide), plants
breath in carbon dioxide and breath out oxygen!
Stomates on leaves are just the openings we have
on our faces (mouths and noses) to let these gases
in and out. When they need to let in more carbon
dioxide, they open their stomates, and when there
is enough carbon dioxide around them, the stomates
Hope that answered your question!
First, think about what you know about "living
things." Sometimes, we tend to think that plants
do not do very much since they seem to not move or
communicate. But guess what? Plants are
very sensitive to the environment and they can
influence the environment as well! The ability
of a plant to "sense" is just a bit different than
what you are used to thinking about when you
consider the senses of an animal.
Plants of course need water, sunlight, air, and
nutrients to survive and reproduce - and these
come from the environment. But plants also
interact with the environment by providing oxygen
(produced through photosynthesis) and helping to
loosen soil through mechanical root action to
name just two. Think also about plants in terms of
how they serve as food and even shelter for some
animals (especially insects). Plants are an
integral part of the environment and every food
web connects to them in some form.
There are some interesting examples of obvious
environmental interaction that you might want to
look for next time you are out and about. Have
you ever grown sunflowers? If you do, you
might note that the heads always turn toward
the sun - so even though it's slow, if you
keep track, you will see that they are facing a
different direction in the morning as compared to
afternoon. Other kinds of plants, such as some
species of primroses, have flowers that open
and close according to sunlight levels. Other
plants have dramatic reactions to touch -
with exploding seed sacs or the ability to snap
shut. Do you know what a venus fly trap is?
Try looking it up or having your parents or a
teacher help you find a video of one on line - now
THERE is a plant that is interacting with it's
Plants interact with their environment in all of
the ways that any other living thing does. They
take in materials they need to grow (in this case,
nitrate, phosphate, carbon dioxide, water, and
light), and release by-products (oxygen). They
also are eaten by many kinds of animal and fungal
life, use animals to move their pollen and seeds
around, and construct defenses against things that
Plants interact with their environment in a
variety of ways. Plants can sense light
and will grow towards it. They can also sense
gravity and will grow up even if there is no
light. Also, vein like plants that need something
to climb up, will move their shoots around in
circles until they touch something that they can
twist around and grow up. Plants also compete
against each other underground, their roots
interact and release chemicals to stop their
neighbors from growing.
