- I= Image size
- I= M*A

- Rules for Scientific diagrams
- Drawing needs a title
- Each drawing should be done with a sharp pencil
and ruler
- draw a square first
- Label the diagram
- Write down magnification of the
drawing
- Drawing needs a title
- Organelles
- nucleus
- contains DNA and controls cell activity
- contains DNA and controls cell activity
- Chloroplast
- in the cytoplasm. They convert light into energy that the plants
use. This is called photosynthesis

- Mitochondria
- where respiration takes place
- where respiration takes place
- vacuole
- large storage space filled with sap. Stores food/nutrients the cell needs to
survive
- large storage space filled with sap. Stores food/nutrients the cell needs to
survive
- Cytoplasm
- holds the cells in place
- holds the cells in place
- Cell wall
- gives cell its shape. Supports thecell
- gives cell its shape. Supports thecell
- Cell membrane
- Controls what comes in and what comes out
- Controls what comes in and what comes out
- nucleus
- Cells
- Red blood cell
- Has no nucleus. carries oxygen around the body
- Has no nucleus. carries oxygen around the body
- Egg cell
- Carries mothers DNA. much larger than any other cell
- Carries mothers DNA. much larger than any other cell
- Root hair cell
- Absorbs minerals and water from soil. It has a larger
surface area to absorblots of water
- Absorbs minerals and water from soil. It has a larger
surface area to absorblots of water
- Sperm cell
- Carries fathers DNA. has a long tail so it can
swim to the egg cell
- Carries fathers DNA. has a long tail so it can
swim to the egg cell
- White blood cell
- Has a flexible shape to help engulf diseases
organism
- Has a flexible shape to help engulf diseases
organism
- Nerve cell
- Carries nerve impulses around body. they have many branches at ends to
connect to other nerve cells
- Carries nerve impulses around body. they have many branches at ends to
connect to other nerve cells
- Palisade cell
- carries photosynthesis by using chloroplast
to absorb sunlight
- carries photosynthesis by using chloroplast
to absorb sunlight
- Red blood cell
- food tests
- Carbohydrates
- Protein
- Lipids (fats and oils)
- Test for starch is IODINE
- Test for reducing sugars is called the Benedict's test
- Test for protein is called the BIURET test
- Test for lipids is called the EMULSION test
- Carbohydrates
- Glucose + oxygen to Carbon Dioxide + Water
- Enzymes
- The substance that binds to the enzyme is
called substrates
- The part where binding takes place is called the
active site
- When the enzyme and substrate are bound together,
it is called enzyme-substance complex
- The name of the substance when it releasessfrom the
enzyme is called a product
- When compared to enzymes in digestion this is a
synthesis reaction
- An enzyme is usually made of proteins.
- Biological catalysts
- Do not get used up
- Substrate (eg insoluble food) fits into the Active site of the
enzyme where it can be broken down or bound together
and then be released
- Enzymes can only react with a specific substreate
- Biological catalysts
- The substance that binds to the enzyme is
called substrates
- Eukaryotic= with a nucleus
- Prokaryotic= without a nucleus
- Prokaryotic= without a nucleus
- Specialised cells- A specialised is a
cell that has adapted to do its
function.
- For example a sperm cell. A sperm cell has a
tail to help swim. There are enzymes in the
head. Has a large number of mitochondria
fro repiration for energy
