Biology Flashcards
(32 cards)
ocular lens
closer to eyes
objective lens
closer to object
course adjustment knob
big zooms
fine adjustment knob
small zooms after course adjustment knob
stage
big flat surface where you put the object
diaphragm
controls how much light is seen by physically blocking the light
light (illuminator)
shoots thru object from bottom
calculations for microscope
ocular lens (x10) multiplied by objective lenses (x4, x10, x40)
Prophase
POLES
- nuclear envelope diaspears
- chromatin condenses to sister chromatids
- centrioles move to poles
- spindle fibres come out from centrioles
Metaphase
M = Equator.
- spindle fibers attach to centromeres.
- push chromatids to center (equator)
Anaphase
ANA THAT YOU HATE ME. SISTERS SEPERATED.
- sister chromatids seperate into daughter chromosomes
- spindle fibres pull the to opposite poles
Telophase
LAST PHASE
- nuclear envelope comes back
- chromosomes go back to chromatin
- spindle fibres disappear
nucleus
-brain
-has dna
mitochondria
-food to energy (atp molecules)
lysosome
recycling
rough er
-has ribosomes
-protein synthesis
smooth er
-no ribosomes
-makes fats/lipids
-detoxifies
cell membrane
wall of fat that holds stuff tgth
golgi appartus
-mailman
-packages and ships things for cell
central vacuole
-for plant
-holds water, minerals, waste
chloroplast
-photosynthesis in plant
-green
cell wall
-gives more structure protection to plant
tympanic membrane
-eardrum
-behind eye
-circular structure
nictating membrane
-clear membrane that attaches to the bottom of the eye
-protects the eye while swimming.
clear little fucker protecting the eye (you had to rip it off to actually see the eyeball)
