1 SUTHERLAND HIGH SCHOOL GRADE 8 NS 2019 CAPS
Respiration SUTHERLAND HIGH SCHOOL GRADE 8 NS 2019 CAPS TB pg. 11

2 TB pg. 11 SUNLIGHT OXYGEN CARBON DIOXIDE GLUCOSE WATER GLUCOSE ENERGY

3 TB pg. 11 ALL living organisms need energy to survive.
In photosynthesis: green plants produce glucose (food). Carbon dioxide + Water Glucose + Oxygen CO2 + H2O C6H12O6 + O2 This glucose is stored as potential energy. Chlorophyll Sunlight Chlorophyll Sunlight TB pg. 11

4 The energy can be released by the plant, in a series of chemical reactions.
In respiration, plants and animals break down glucose and release carbon dioxide, water and energy. Glucose oxygen carbon dioxide + water + energy C6H12O O2 CO H2O + energy Write down TB pg. 11

5 Opposite processes TB pg. 11

6 TB pg. 11 PHOTOSYNTHESIS CO2 + H2O C6H12O6 + O2 RESPIRATION
C6H12O O2 CO H2O + energy TB pg. 11

7 During photosynthesis, plants use energy from the Sun to produce .
During respiration food is broken down and is released. TB pg. 11

8 DO WE REALLY RELEASE CARBON DIOXIDE?
Activity 6 pg. 13: Test for presence of carbon dioxide in exhaled air TB pg. 13
