Happy Wednesday! Bellwork: February 25
In your own words DEFINE the word “Tropism”.
Give examples of what the following four tropisms may look like in a plant’s “real life”
(remember the video from Monday)Gravitropism (+/-) , Hydrotropism,
Phototropism, Thigmotropism
Grade Info
• No tutorials today!• I will take work until Friday
afternoon• You’ll have a plant test Monday• The plant system interaction homework
will count for next grading term
Anticipation Thoughts…(true or false?)
1. Thigmotropism is a plant’s response to gravity.
2. Plants breathe3. Plants need oxygen to survive4. Singing helps plants grow5. Plants produce glucose during
photosynthesis.
Cellular Energy
Essential Question: How are photosynthesis and cellular
respiration related?
How is energy transformed in living organisms?
• Energy :the ability to do work
• Most energy comes from the sun in the form of light.
• All energy that is not
used by organisms leaves the
Earth in the form of heat.
• Adenosine triphosphate (ATP) is the chemical that cells use to store and release energy.
• The energy in ATP is stored in the bonds between the elements.
How do plants make their own food?
• To perform photosynthesis, plants need:1. sunlight (energy source)2. water3. carbon dioxide
These are called the reactants.
• After photosynthesis, the plant has produced:1. Glucose (molecule that the plant uses to
produce energy)2. Oxygen (given off through the leaves)
These are called the products.

SUNLIGHT
The equation of photosynthesis is:
6CO2 + 6H2O + sunlight C6H1206 + 6O2
carbon dioxide + water + energy glucose + oxygen
Talk to your partner:Where do plants take in carbon dioxide?
Where do plants take in water?
Photosynthesis occurs in an organelle in the leaves.
Chloroplasts: organelle where photosynthesis takes place
Chlorophyll: pigment in chloroplasts, makes plants green
How do animals get energy for living?
• Cellular respiration: the process that releases energy (ATP) by breaking down glucose.
• Cellular respiration occurs in the mitochondria of plant and animal cells.
• Cellular respiration makes 36 ATP molecules
• The remaining energy is lost as heat.
Mitochondria
Talk to you partner:
If humans do not make our own food in photosynthesis, how do we
get nutrients to perform cellular respiration?
The formula for cellular respiration is:
6O2 + C6H12O6 6CO2 + 6H2O + Energy
oxygen + glucose carbon dioxide + water + ATP
Cellular respiration requires oxygen and glucose and gives off carbon dioxide,
water, and energy.

Debrief:
Explain the relationship between cellular respiration and photosynthesis in terms of matter.
What about energy?

Let’s Race!• I’m giving you a set of manipulatives.• When I say “products of photosynthesis” for
example. The first table to correctly build it earns a point. EACH person must be correct!
• Table that earns the most points wins (at life)!!
