Plant Structures and Functions: Lesson 3

Photosynthesis & Respiration: What do we already know?

BrainPOP Teaser1) Why is the plant green?

2) What is the function of the chloroplasts?

3) Why do you think it is helpful for leaves to be wide?

Plant Structures and Functions: Lesson 3

a) Chloroplast gives it its color

a) It converts water, sunlight and carbon dioxide into sugar and oxygen

a) It has more room for sun to hit, which provides more energy for photosynthesis.

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) -

2) -

Quick Check-Draw conclusions: How are the

chloroplasts like tiny factories?

1) Plant Structures and Functions: Lesson 3

Create oxygen & sugar in the process of photosynthesis

Provides glucose for the plants energy

They take in items (sunlight, water & carbon dioxide) and produces something new (glucose & oxygen).

2) What is the photosynthesis and respiration cycle?

• -

Quick Check-Draw Conclusions: In what ways do

animals

depend on plants• -

Plant Structures and Functions: Lesson 3

Photosynthesis & Respiration: Main Ideas

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

They rely on plants for oxygen and energy.

3) Where does respiration happen?• -

Quick Check-Draw Conclusions: Why are the

mitochondria in

plant cells important• -

Plant Structures and Functions: Lesson 3

Photosynthesis & Respiration: Main Ideas

Mitochondria

They provide energy for plants to grow and repair themselves
