After watching the introduction video please take the time to watch the videos that follow this.
1. Why are plants called 'producers"?
2. Describe the process of photosynthesis.
3. What are the two phases of photosynthesis?
4. Is a greenplant a heterotroph or an autotroph and why do you say that?
5. What does photosynthesis require?
6. What does photosynthesis produce?
7. What is the cause for plants to be green in colour?
8. What colour does the leaf change when starch is present?
9. Click on the link and copy the drawing or download the picture and Label the chloroplast.

Process
Photosynthesis
With the introduction video you will watch the video's and click on the links to see the pictures and articles that will give you a better idea on photosynthesis and it will help you answer the questions in the activity. While seeing the video's; pictures and articles open you mind and you will gain knowledge on
1. what photosynthesis is;
2. know what a autotroph is;
3. what is the reactants and products of photosynthesis;
4. you will know how to check for starch in a plant;
5. you will know how to identify what and where light and dark phase takes place;
6. you will be able to differentiate and explain light and dark phase of photosynthesis;
7. lastly you will be able to identify the chloroplast and name its parts
It might seem much but everything links which makes it easier to remember.

Questions Explanation on how to answer the question How to give marks
| Question 1 | To answer this question you give the definition of a producer and link it to what green plants do. |
2 Marks:1 mark for definition and 1 for linking green plants and producers. |
| Question 2 | To answer this question the learner gives the process of photosynthesis by including the words radiant energy and chemical energy. | 2 Marks: 1 mark for radiant energy and chemical energy and 1mark for the result of it. |
| Question 3 | Mention the correct full term of the two phases of photosynthesis. | 2 Marks: 1 mark per correct phase given. |
| Question 4 | Answer by giving the correct term and a logical reason why you chose that term. | 2 Marks: 1 mark for correct term and 1 mark for reason. |
| Question 5 | Give two things that goes into photosynthesis. | 2 Marks: 1 mark for each reactant given |
| Question 6 | Give two things we get from photosynthesis. | 2 Marks: 1 mark for each product given. |
| Question 7 | Give the scientific name for the reason why plants are green (what causes the green colour). | 1 Mark: spelling of the word should be clear and correct. |
| Question 8 | The correct name of the solution should be given. | 1 Mark: correct spelling of the solution and the whole term should be given. |
| Question 9 | Label the picture exactly to where the lines are pointing to. labels and parts should be clear. | 6 Marks: 1 mark per correct label. |
| Question 10 | Give atleast three differences for each phase. Tabulate | 7 Marks: maxiumum 3 marks for a difference in each phase. This answer must be in table form or no marks will be given. |
Your mark: /27
