plants convert energy from sunlight into food stored as
carbohydrates. Plants also provide the oxygen humans and animals
breathe, because plants use carbon dioxide for photosynthesis and release
oxygen into the atmosphere.
A sunflower looks like one
large flower, but each head is composed of hundreds of tiny flowers called
florets, which ripen to become the seeds. This is the case for all plants in
the sunflower family, including daisies, yarrow, goldenrod, asters, coreopsis,
and bachelor's buttons.
3. Strawberry Seeds
The average strawberry has
200 seeds. It's the only fruit that bears its seeds on the outside.
4. The Venus Flytrap
Some plants are carnivores, gaining nutrients
by eating various small insects and spiders. A well-known example of a
carnivorous plant is the Venus Flytrap.
5. The Pitcher Plant
The pitcher plant is also a
carnivorous plant. They get their nutrition from insects they
"catch," after converting them into a form they can digest or absorb.
6. Grass Distress Call
The smell of freshly cut
grass is actually a plant distress call.
7. Other Plants Call For Help Also
When some plants are being
eaten by caterpillars, they send chemical signals to parasitic wasps who swarm
and attack the caterpillars.
Figs are not always
considered vegan. When pollinated by a fig-wasp, the fig’s inward facing
flowers trap the wasp, and the corpse is digested by enzymes in the fig.
9. Oxygen From Trees
In one year, the average
tree gives off enough oxygen to allow four people to breathe for a year. You
breathe 6 liters of air per minute. One tree can filter up to 27 kg
of pollutants from the air each year.
10. Trees and Nutrition
Trees get about 90% of
their nutrition from the atmosphere (carbon dioxide, etc), and only about 10%
from the soil.

whose hope is in the LORD his God:
