1. Plants Photosynthesis and inheritance Topic Target:
Lesson 1 How do plants Grow?
Lesson aims
To study the process of photosynthesis by which plants make their own food,
To interpret data linked to the process and learn to explain the term biomass.

2. Learning outcomes By the end of the lesson you should
be able to explain the terms photosynthesis and biomass
know that as an organism grows it increases biomass - growth requires food
understand the process of photosynthesis - raw materials, role of light and chlorophyll and the word equation

3. On your mini whiteboards
Write down the things you think plants need to grow

4. Look at the plants Questions What do plants need to grow?
Where does their food come from?
How?
Do plants need soil?

5. In your books draw a plant and label all the things it needs for growth
Summarise how plants grow and define the terms: photosynthesis - biomass -

6. Photosynthesis and biomass
definitions:
Photosynthesis is the process a plant uses to make food and grow.
Biomass is the mass of materials that a plant or animal is made of.

7. Photosynthesis research
You need to find / confirm the following information through research and record references.
(You should give book title, author, and page.)
Raw materials required for photosynthesis (2)
How these raw materials are taken in by the plant
Why light is important
How light is absorbed
Food made
Word equation (Extension symbol equation )
How food is stored in plant

8. The word and chemical equations for photosynthesis:
Sunlight
Carbon dioxide + water glucose + oxygen
6CO H20 C6H12O O2
Chlorophyll
Sunlight
Chlorophyll

9. Four factors affect photosynthesis:
Light – if there is more light photosynthesis happens faster
Water – if there is not enough water photosynthesis slows down
Temperature – the best temperature is about 300C – anything above 400C will slow photosynthesis right down
CO2 – if there is more carbon dioxide photosynthesis will happen quicker

10. Watch the animation and answer the question:
Why is deforestation of the Rain Forests a problem?
Suggested homework

11. HOMEWORK:Use a dictionary to find out : What does the word photo mean
HOMEWORK:Use a dictionary to find out : What does the word photo mean? What does synthesis mean? What do you think photosynthesis means ? Explain

12. Learning outcomes Can you explain the terms photosynthesis and biomass
explain that as an organism grows it increases biomass - growth requires food
understand the process of photosynthesis - raw materials, role of light and chlorophyll and the word equation
