2. The plants
What are plants?
Plants are living organisms that produce their
own food through the process of
photosynthesis. They capture the energy of
sunlight through chlorophyll and convert
carbon dioxide and water into sugars used as
an energy source.
3. Parts of a plant:
Root: its function is attached to the plant. Through it plants
obtain nutrients.
Stem: is the one that gives support to the plant; some
stems are thin and flexible, others, such as trees, are
woody and hard.
Blade: is the structure where photosynthesis and
respiration takes place.
Flower: the reproductive organ. all organs needed to
produce fruit and seed The interior has.

4. What we know about plants?
They are living beings born, feed, reproduce and die;
that's what little we know of them, but now know a little
more.
Plants are living beings like animals eat, breathe and
reproduce. Unlike the animals can not move the plants
nor feel. But they can do something that animals do,
like make their own food (nourishment) by chlorophyll
photosynthesis.

5. What are the essential elements for a plant to
grow?
Plants need soil, air, water and light; the same
elements that humans need to survive, to
eliminate him only one of them die.

6. Soil is the top layer of the earth's crust. In him the
seed germinates and the plant roots to stay delves
right, developed and nurtured. In the soil the plants
are all essential nutrients to survive. Each of these
nutrients has a specific function: allows the growth
match; nitrogen stimulates the production of
abundant leaves; potassium and calcium promote
the harmonious development of plant and iron
increases the green coloring.

7. The air is necessary to the life of man,
animals and plants element; without it we
could not live. The air is everywhere, at home,
on the street, in the countryside. The whole
earth is surrounded by air. Live plants if they
lack the air and doing the experiment can
prove Plant and Air.

8. Light all human beings,
animals and plants need
energy for their life
processes. Just as humans
need a good diet, plus
vitamins for energy, green
plants use energy from the
SOL to survive. With the
sun, make their own food, so
they are not producing
organisms, because they
produce their own food.

9. Water like air, light and
soil is another basic and
indispensable elements
for plants to germinate
and achieve the desired
growth.
