Plant Structures and Functions: Lesson 3
Photosynthesis & Respiration:
What do we already know?
BrainPOP Teaser
1) Why is the plant green?
a) Chloroplast gives it its color
2) What is the function of the chloroplasts?
a) It converts water, sunlight and carbon dioxide into
sugar and oxygen
3) Why do you think it is helpful for leaves to
be wide?
a) It has more room for sun to hit, which provides
more energy for photosynthesis.
Plant Structures and Functions: Lesson 3
Photosynthesis & Respiration:
Vocabulary Part I
1) Photosynthesis: leaves use sunlight, carbon dioxide and
water to make food for the plant & oxygen is a
byproduct.
2) Stomata: Is where carbon dioxide & oxygen enter & leave
the leaf.
3) Carbohydrate: it is a form of sugar made up of carbon,
hydrogen and oxygen.
4) Cellular Respiration: breaking down or use of
carbohydrates for energy.

Plant Structures and Functions: Lesson 3
Photosynthesis & Respiration: Main Ideas
1) What do leaves do?
1) - Create oxygen & sugar in the process of
photosynthesis
2) -
Provides glucose for the plants energy
 Quick Check
-Draw conclusions: How are the chloroplasts
like tiny factories?
1) They take in items (sunlight, water & carbon dioxide)
and produces something new (glucose & oxygen).
Plant Structures and Functions: Lesson 3
Photosynthesis & Respiration: Main Ideas
2) What is the photosynthesis and
respiration cycle?
• -
Photosynthesis: A leaf takes in carbon dioxide, sunlight & water to
produce glucose and oxygen.
Respiration: is when oxygen & glucose is used to create energy and
the byproduct water & carbon dioxide
 Quick Check
-Draw Conclusions: In what ways do animals
depend on plants
• - They rely on plants for oxygen and energy.
Plant Structures and Functions: Lesson 3
Photosynthesis & Respiration: Main Ideas
3) Where does respiration happen?
• - Mitochondria
 Quick Check
-Draw Conclusions: Why are the mitochondria in
plant cells important
• - They provide energy for plants to grow and repair
themselves
