Give two differences between plant and animal cells.
Answer (any two of):
plant cells have a cell wall, animal cells do not
plant cells have permanent vacuoles, animal cells do not
plant cells have chloroplasts, animal cells do not
What are the cells walls of Fungi made of?
Chitin
How do fungi reproduce?
Via spores
Are protoctista unicellular or multicellular?
Unicellular
Are bacteria unicellular or multicellular?
Unicellular
True of false: Bacteria have DNA in a nucleus
FALSE: Bacteria do not have a nucleus
What is the test for glucose? (Also called reducing sugar).
Describe what chemical solution is used and how to carry out the experiment.
Benedicts solution.
Add Benedicts solution to a test tube with whatever you are testing inside. Put in a boiling water bath. Take out and observe the colour.
What is the test for starch?
Iodine solution.
Add a few drops to the sample.
What is the test for fats/ lipids?
Elthanol.
Add drops to a test tube with sample. Add water and shake.
What is the test for starch?
Iodine solution.
Add a few drops to the sample.
What is the test for fats/ lipids?
Ethanol.
Add drops to a test tube with sample. Add water and shake.
What is the test for protein?
Biurets solution.
Add solution to sample and shake.
What elements are in carbohydrates?
Carbon (C), Hyrdrogen (H), Oxygen (O)
How do you know if starch is present?
It will go blue/black
How do you know if Protein is present?
It will go mauve/purple
How do you know if sugar is present?
It will go red/ orange/ green/ yellow
(Depends on how much is present. Red if lots)
How do you know is lipids are present?
Milky white/cloudy
What is a monomer?
A small molecule that can join end-to-end with other monomers to form a polymer molecule.
What is a polymer?
A large molecule formed from many identical, smaller molecules known as monomers.
