TEST: Photosynthesis & Respiration Wednesday 15th

On Wednesday 15th August you will be having a test:

The test will have three sections:
1. Multiple Choice Section
2. Short answer questions (about a short paragraph of writing required)
3. Analysis of a photosynthesis or respiration experiment (like one we've done in class).

----
The types of questions being asked will be:
- What is photosynthesis and respiration: What are the reactants and products of each>
Watch: Bozeman Photosynthesis  
Try looking at BBC Bitesize: Carbon Dioxide and Respiration 

- Why is photosynthesis important? How has/does photosynthesis effected the planet?  SHORT ANSWER
Try looking at this TED ED video or Cambrian (early animal) Explosion wiki  or watch: Photosynthesis and Global Climate

- Where does photosynthesis and respiration occur?
Watch this interaction: Photosynthesis Interactive  and Respiration Interactive

- What is the similarities and differences of respiration/photosynthesis?

Photosynthesis	Respiration
Makes Glucose  Uses Glucose	Makes Glucose  Uses Glucose
Makes Carbon Dioxide  Uses Carbon Dioxide	Makes Carbon Dioxide  Uses Carbon Dioxide
Makes Oxygen Gas  Uses Oxygen Gas	Makes Oxygen Gas  Uses Oxygen Gas
Occurs in the chloroplasts  Occurs in the mitochondria	Occurs in the chloroplasts  Occurs in the mitochondria
Occurs continuously  Shuts down at night	Occurs continuously  Shuts down at night

Also there will be questions about:
- Reading the periodic table and understanding proton, neutron and electron count from it
Watch: How to read the periodic table (also notes on the power-point below)

- Reading a chemical equation and understanding its notation (numbers and letters)
Watch Writing and Reading a Chemical Equation (also notes on the power-point below).

- Conservation of mass principle and how it is applied to chemical reactions (like photosynthesis and respiration)
Look at this: Conservation of Mass and Chemical Reactions

Also there will be questions about:
- Your assignment - volcanoes and how first life formed (multiple choice)
-  Snowball Earth: How it started, its impact on life, and how it finished SHORT ANSWER
If you have completed the assignment and looked at the resources there, you should be fine to answer these questions.  Look at the assignment link below for more help.

Experiment Question:
This question will get you to analyse the results of an experiment and answer some questions in relation to photosynthesis and respiration.   To prepare for this question you should have a thorough understanding of these two chemical reactions and have a think about some of the experiments we have done in class: Finding starch in leaves and testing acidity of algal balls.
