What are the seven life processes?
Movement Reproduction Sensitivity Growth Respiration Excretion Nutrition
What are all organisms made form?
Cells
What is the function of the cell surface membrane?
Keeps the cell together and controls what goes into and out of the cell.
What is the function of the nucleus?
Controls the cell
What is the function of the cytoplasm?
Is the place where activities happen (for example, respiration in mitochondria)
What is the function of chloroplasts?
Contain chlorophyll to trap sunlight for photosynthesis.
What is the function of the cell wall?
Provides support (is made out of cellulose).
What is the function of the vacuole?
Serves as storage space
What is A?
Cell surface membrane
What is B?
Nucleus
What is C?
Cytoplasm
What is D?
Chloroplast
What is E?
Vacuole
What is F?
Cell wall
What type of cell is cell A?
Animal cell
What type of cell is cell B?
Plant cell
Total magnification =
Total magnification = Magnification of objective lens x magnification of eyepiece lens
How is the object you look at through a microscope called?
Specimen
What would you see if the specimen is very thick? Why?
Nothing would be seen. If the object is too thick, no light can pass through.
Where is the specimen placed?
Onto a slide (with a drop of water)
What is placed on top of the specimen? Why?
A coverslip. To prevent the specimen drying out, hold it flat, and stop it from moving.
Why is sometimes a stain used?
To help you see parts of the cell trough a microscopic cell
what means if a cell si specialised?
It is adapted for a particular questions
What do muscle cells do?
Shape to move things
What do root hair cells do?
Take in water
What do fat cells do?
Store fat
What do xylem cells do?
Carry water
What is a tissue?
A group of cells that are the same, all doing the same job. (i.e. musle tissue)
What is an organ?
A group of different tissues working together to do an important job.
(i.e. the heart is made out of nerve, muscle and fat tissue)
What is A and what is its function?
Lungs: get oxygen into the blood for respiration and excrete carbon dioxide.
What is B and what is its function?
Heart: pumps blood
What is C and what is its function?
Liver: makes, stores, and breaks down substances.
What is D and what is its function?
Diaphragm: helps breathing.
What is E and what is its function?
Stomach: breaks up food.
What is F and what is its function?
Kidneys: Clean the blood and produce urine to excrete wastes. We have one on each side.
What is G and what is its function?
Small intestine: Breaks up food and absorbs it, to provide nutrition for the body.
What is H and what is its function?
Large intestine: removes water from unwanted food.
What is H and what is its function?
Rectum: stores faeces (waste materials and unwanted food.
What is I and what is its function?
Bladder: stores urine.
What is A and what is its function?
Leaf: traps sunlight to make food for the plant.
What is B and what is its function?
Stem: carries substances around the plant and supports the leaves and flowers.
What is C and what is its function?
Root: holds the plant in place. Roots also take water and small amounts of other substances to the soil.
What is the job of the breathing system?
Takes air into the body and gets rid of waste gases.
What is the job of the circulatory system?
Carries oxygen and food around the body.
What is the job of the digestive system?
Breaks down food.
What is the job of the nervous system?
Carries signals around the body.
What is the job of the urinary system?
Gets rid of waste.
What is the job of the locomotor system?
Allows movement.
What is the job of the water transport system in plants?
Carries water up a plant.
