• Middelbare school
• havo
• Leerjaar 3

Unit 1: combustion and breathing

Planning for today

• Instruction BS. 1.1  Metabolism                               15 min.
• Make exercises 6 to 9                                                 15 min.
  
• Quiz (check up)                                                              10 min.

At the end of lesson 

... you can explain how plants hold energy in glucose during photosynthesis.

... you can explain that breaking down glucose releases energy.

During the instruction 

Make notes in a notebook :)

Where do plants get their energy from? 

How do plants capture the energy from the sunlight? 

make notes

How do plants capture the energy from the sunlight?

• water + CO2+ sunlight → glucose + O2
  

• converting substances into other substances = metabolism

Maarten van der Weijden

 195 km in 4 days!

• Where did he get the energy from?
• What role did the respiratory system play?

How does energy come free?

Glucose can be broken down. This happens in the mitochondria.​

Important! Both plant and Animal Cells have mitochondria. 

​Energy comes free when glucose is broken down. This process is called combustion.

​

Now get to work

• Make exercise 6 to 9 

What you don't finish will be homework!

Quiz!

A plant needs oxygen for photosynthesis.

1. True
2. False

What isn't released during photosynthesis?

1. Zuurstof
2. Glucose
3. Koolstofdioxide

Carbon dioxide 

Water

Chloroplast

Leaf

absorbed by roots from the soil 

Diffuses into the leaves from the air

Aborbs light energy

Contains chorophyll

Carries out photosynthesis

At night there is photosynthesis in plants

1. True
2. False

Question 6: lichens

A lichen consists of two types of organism: algae and a fungus. Algae are unicellular plants with chlorophyll but without a stem or roots. In a lichen, the algae are enclosed between two layers of mycelium (= the fungus).
