What does an animal cell contain?
- a nucleus
- cytoplasm
- mitochondria
- ribosomes
- cell membrane
What does a plant cell contain that an animal cell doesn’t?
- a cell wall
- a permanent vacuole
- chloroplasts
What does a nucleus contain?
It contains genetic material
What is the cytoplasm’s use?
It is where most of the chemical reactions happen
What is the mitochondria’s use?
It is where most of the reactions for aerobic respiration take place
What is the cell membrane’s use?
It controls what goes in and out
What is the Ribosomes’ use
It is where the proteins are made
What is the use of a cell wall in a plant cell? What is the cell wall made of?
It strengthens the cell
What is the cell wall made of?
It is made of cellulose
What is chloroplasts use in the plant cell?
It is where photosynthesis occurs
What is the use of a Permanent Vacuole in a plant cell?
It contains cell sap
What is the difference between a prokaryotic cell and a eukaryotic cell?
- It has a cell wall, unlike the animal cell
- it doesn’t have a true nucleus, its DNA is floating around in the cytoplasm
- They are tiny compared to eukaryotic cells
What are the two groups of prokaryotic cell?
- bacteria
- archaea
What was invented first: the electron microscopes or the light microscopes?
light microscopes
Electron microscopes have a higher _____________ and __________ than light microscopes.
Electron microscopes have a higher magnification and resolution than light microscopes
Electron microscopes let us see _______ things in ____ detail, meaning we can understand ___________ __________ better now
Electron microscopes let us see smaller things in more detail, meaning we can understand subcellular structures better now
Magnification-
(equation)
magnification= image size/real size
true or false: never use standard form to write really numbers
false
