Cells & Microscopy Flashcards
How do you calculate magnification?
Image size ÷ actual size
What 3 features do plant cells have that animal cells don’t have?
Cell wall
Chloroplast
Permanent Vacuole
Why is stain added to cells before using the microscope to view them?
To see the image clearer
Give an example of a prokaryotic cell
Bacteria cell
State the function of mitochondria
Carry out respiration and release energy
State the function of ribosomes
the site of protein synthesis
State the function of the nucleus
Controls the cell and contains DNA
State the function of cytoplasm
Where chemical reactions take place
State the function of the cell membrane
Controls what enters and leaves the cell
State the function of the cell wall
For strength and support of the cell
State the function of the vacuole
Stores cell sap
State the function of chloroplasts
Where photosynthesis happens
Which part of the cell controls what enters and leaves?
Cell membrane
What do you do if the cells are blurry?
Turn on the focusing wheel
What do you do if the cells are very small?
Turn the objective lens to a higher magnification
