Cell Parts-Microscope Flashcards
(25 cards)
Nucleus
Control center
Mitochondria
Powerhouse of the cell
Vacuoles
Store food water and other nutrients the cell needs
Cell wall
Outer covering of plant cell. Gives plant cells their shape
Cytoplasm
Gel-like substance. Takes up the empty space inside the cell
Lysosomes
Get rid of unwanted and old warn out cell parts
Cell membrane
Double-layered covering of both plant and animal cells. Provides protection and controls what comes in and out of the cell
Chloroplast
Where photosynthesis takes place. Gives plant cells their green color.
Chromosomes
Instruction manual located inside the nucleus
Ribosomes
Where proteins are manufactured
Golgi body
Transports things around in and out of he cell. It’s like the delivery guy.
Endoplasmic reticulum
Packages proteins for transport. Can be smooth or rough
Diaphragm
Controls the amount of light intensity that shines through the microscope
How do you find the total magnification of a compound light microscope
Multiply the power of the eyepiece lens with the objective lens
Where does photosynthesis take place?
In a plant cell inside the chloroplast
Who is generally given credit for developing the first microscope?
Anton von Leewenhoek
What type of microscope has two or more sets of lenses?
Compound microscope
What type of cell lacks a nucleus and membrane bound organelles.
Prokaryotic Cells
Why does a plant have to undergo photosynthesis in order to survive?
Because that is how it makes its own food and growth/reproduction.
If you were to look at a speciman under the microscope, explain the first few steps.
1) Lower the stage all the way.
2) Make sure you are using the low power lens
3) Place the slide on the stage and use the stage clips to hold in place.
4) Turn on the light source, and while looking through the eyepiece lens very slowly turn the course adjustment until the specimen comes in to view.
True/False: Plant cells are round, animal cells are rectangular
False
This cell organelle contains the DNA
Nucleus
Animal cells tend to be what shape?
More round.
What cell part is considered to be semi-permeable
the cell membrane because it allows certain things to pass through and not others
