What is the difference between respiration and breathing
Respiration - chemical process in which you release energy made from food
Breathing - physical process in which you inhale and exhale using your lungs
Give and example of movement for animals and plants
Plants open and close and grow from getting nutrients and water
Animals walk around
Sensitivity for plants and animals
Knowing your surroundings - flowers move towards the sunlight
- animals can feel pain
Difference between excretion and egestion
Excreation is extracting toxic waste from your body - weeing
Egestion is taking out undigested food from your body - pooing
Sponge living or non living

Non living
Equation for photosynthesis
Carbon dioxide + water ➡️ oxygen + glucose
Equation for respiration
Glucose + oxygen (arrow) water + carbon dioxide + energy
What do plants excrete
Carbon dioxide and water vapour
What does a cell wall do
It protects the cell and prevents it from bursting
Mitochondria
Where aerobic respiration occurs
Cytoplasm
Where chemical reactions occur
Ribosomes
Make protein
Nucleus
Where DNA is kept and controls the activity of the cell
Cell membrane
Allows substances to come in and out of the cell
What are the three things that are not in an animal cell
Chloroplast - where photosynthesis takes place
Vacuole - store and dispose substances
Cell wall - prevents cell from bursting
Why do we use a microscope
Objects that are too small to see with the naked eye i.e: (bacteria - microscopic)
What is contained in an Eye piece focus
Holds a lens
What does the course focus do
Used for making large adjustments to the focus of the specimen
What does the fine focus do
Go into an image with more detail than the course focus
What does the objective lens do
Presents the image of the object to the eye piece
What does the stage do
Holds the slide
What does the mirror do in a microscope
It reflects the light allowing the person to see the specimen clearer
What does the slide do
It holds the specimen
If an eyepiece lens has a magnification of *10 and objective lens of *4 = …
40 magnification
If an eyepiece lens has a magnification of 10x and the objective lens has a magnification of x20, what is it’s total magnification = …
x200
