Plants
Producers
• Producers are the ONLY organism that can
take the sun’s energy and make food
(photosynthesis).
• Producers feed consumers.
• Producer’s roots help anchor the plant in the
ground, give nutrients/water to the plant, and for
us, roots hold the soil in place in our yards.
Producers MUST have four
things to survive:
• Water
• Nutrients from whatever they are planted
in (water, rocks, soil)
• Carbon dioxide (CO2)
• Sunlight
Name two types of roots.
Fibrous root
Tap root
• See samples
• homework
Edible Roots
How do seeds gets spread around?
• Wind can blow seeds
off of a plant.
• Water, like rain, can knock seeds off
plants.
• Animals or people brushing up against a
plant can have seeds stick to their
clothing.
• People can move seeds around.
• Birds eat seeds. They then poop the seeds out
in another location.
• The seed has fertilizer around it (feces) and it
can grow where it lands.
What shape leaf is best for
photosynthesis?
sunlight
carbon
dioxide
water
Nutrients/nitrogen
What type of leaf do you think will be
able to get more sunshine into it?
The bigger the leaf,
the more photosynthesis.
Plants must hold on to their water
especially in dry areas.
What type of leaf would hold on to its
water longer?
Steps of a plant’s life cycle are...
Steps of a plant’s life cycle are...
Tropism
When plants “react”!
Tropism
All living things respond or react to their
environment.
–temperature
–weather
–other organisms
Plants also react to stimuli. This is
called tropism.
What is tropism?
The way a plant behaves due to certain
environments.
Example: Look at your eco-columns.
• Growth towards the sunlight
• Roots always grow down
Sunlight
Plants react to
sunlight. The sides
away from the sun
grow longer and
the plant starts to
bend towards the
light.
Darkness
Other plants may react
from darkness or lack
of light. Morning
glories close up at
night when they react
from the lack of
sunlight.
Gravity
Like everything else on
Earth, plants also
respond to gravity. A
plant’s roots grow
down into the soil due
to the pull of gravity.
This also anchors the
plant into the ground.
Venus Fly Trap
These plants are very different
from normal plants.
1) Since they eat insects and
meat,
they are consumers.
2) They respond to touch.
When something touches
one of its sticky hairs, they
bend and trap the animal
inside.
Touch
Another plant that
responds to
touch is the
mimosa plant.
This Hawaiian
fern plant closes
up when
touched.
What is an inherited trait?
It is a trait that an animal or plant is created or
born with. The trait MUST come from family of
the plants or animals.
It is NOT something that the animal or plant
learns to do.

traits of plants?

What is a habitat?

What is a niche?
A niche is the job an organism has in life.

What is a decomposer?
