Lesson 1: Importance of Plants and Photosynthesis
Learning Outcomes – The aim of this lesson
• To develop my knowledge and understanding (KU) of the importance of plants and photosynthesis.
• I can describe the various uses of plants
• I can identify structures found within a plant cell
• I can state what photosynthesis is
Success Criteria – What you will learn in this lesson
Various uses of Plants
Can you think of why a coconut
tree is useful to us?
Coconut palm
Tea & Coffee 2. What everyday substance is made from this plant?
3. What are the wet fields called, and what crop is grown in them? 4. Give a reason why the Amazon Rainforest should NOT be cut down for agricultural land?
5. What flowers are these and where are they grown? 6. Why were these onions boiled in the past?
7. What is being collected from the tree? 8. What are the 4 main fibrous ingredients that make up cereals?

9. What other ingredients (that are obtained from plants) are added to cereals for flavour?
10. What is the name of this crop and the important export made from it?
Various uses of Plants
1) Food Coconut milk can be used to make curries and puddings 2) Building Materials The leaves can be used to make a roof. The tree trunks can used to make bridges across narrow rivers. The fibers from the bark of the tree can used to make rope. 3) Medicine Coconut water can be used to restore your body salts and water when you are dehydrated.
Coconut palm
Uses of plants
• Copy the table
• Work together with the others in your group to complete table – use plants other than coconuts!
Area of use Plant Use
Food
Medicine
Raw materials
Uses of plants
• Plants also help keep the balance of gases in the atmosphere.
CO2 produced in respiration
CO2 taken in
O2 taken in
O2 given out Do you know the name of this process?
Photosynthesis
• Watch the following video to identify:
What is photosynthesis?
What do plants need to photosynthesize?
What do plants release once they have photosynthesised?
Chemical reactions in our whole body In your pairs, think (i) what is respiration (ii) what substances do you take into your body, and what substances you give out.
Respiration
Take into our body Give out from our body
Respiration
Glucose + Oxygen water + carbon dioxide
Energy
Respiration is the breakdown of food (glucose) to release energy! Word equation:
+ +
• Look the results from the experiments set up at the beginning of the class.
• In which bottle do you think the leaves are:
(i) Photosynthesising
(ii) Respiring
(iii) Why?
Checking CO2 levels Taking

Homework due: 00/00/0000 Exit Pass
To leave this class you must write down one thing you have either:
• Open your jotters to your homework and swap with the person sitting across from you.
• Homework /15
Homework 3 Due!
1. What is respiration?
2. What gas is used in respiration?
3. What gas is given out during respiration
4. If a plant does not have access to sunlight, will it photosynthesise or respire?
5. What happens to the concentration of CO2 inside an enclosed bottle during respiration?
Respiration Recap Learning Outcomes
• To develop my KU of the Carbon Cycle
• I can state what climate change, global warming, and the green house effect is
• I can give an example of a green house gas.
• I can give examples of processes with contribute to climate change.
• I can describe the process of maintaining a balance between the gases in the air
• I can identify causes and implications of changes in atmospheric gas balance.
Success Criteria
Definitions
Climate Change
Any long-term change of climate elements (such as temperature, pressure, or winds) sustained over several decades or longer. There is thought that this is contributed to by human activity.
Global Warming
Carbon
Footprint
Greenhouse
Effect
Greenhouse
Gases
Carbon
Offsetting
an increase in the planet’s average temperature over time.
the amount of carbon dioxide (CO2 ) produced from the activity of an individual or a group.
the process of trapping heat from the sun in the atmosphere
CO2 , methane and water vapour.
ways of balancing increasing CO2 levels in the atmosphere
Carbon Cycle
CO2 in air
1. CO2 is taken in by plants for PHOTOSYNTHESIS and turned into carbohydrates
2. Plants release CO2 through RESPIRATION
3. - EATING
The carbon taken in by plants is then eaten by animals
4. Animals release CO2 through
RESPIRATION 5. – DEATH
Animals (and plants) die and their remains are fed on by microbes
6. These microbes also release CO2 through RESPIRATION

Choose one of the following topics to Research and Present. Find out about all the gases in the air – Use a pie chart to show how the air is made
up of gases and in what percentage. What happens if any of these are altered?
What is meant by your ‘carbon footprint?’ How can you change your lifestyle to reduce it?
What is meant by ‘carbon footprint’ and ‘carbon offsetting’? – Give examples to illustrate your definitions.
What is the Greenhouse Effect? – and Enhanced Greenhouse Effect? Include in your explanation the gases involved and ways we can reduce the effect.
Global warming – What is this and what are the factors that contribute to it?
What is ‘climate change’ - what evidence is there that it is induced by human activity? - include evidence and examples
