chapter 7 overview Flashcards
what is the actual size calculation
fov/fit
what is drawing mag calculation
it is drawing size/actual size
spontaneous generation (abiogenesis) def
living things coming from non-living things
francesco redi what did he do
he proved biogenisis with container experiment
paster what did he do
believed that air had a active principle proved by broth in the flast
what did Antony find out
first person to describe single-celled micro-organisms
what did rudolf accomplish
made microscope observations of dividing cells from multicell organisms
what did Matthias and Theodor find out
they teamed up and found out all plants have cells
cellular knowledge helped us know what
more about stem cells
sexual reproduction
growth/regulations
bacteria infections
what is cancer
it is a rapid repetition of cell division
what are stem cells
they are blank starting cells
how are animal cell and plant cells able to help each other
animal cells help plant by giving carbon dioxide and H2O and plant give us oxygen
cell membrane def
door / passage way chooses what wants to pass
nucleus def
brain, holds dna from chromosomes
nucleous def
boundary between cytoplasm and inside nucleus produces ribosomes
lyposomes def
breaks down, kills infection mircoorganisms
er def
packges sends to golgi lipids ribosomes
er smooth
produces lipids fats
er rough
produces ribosomes
golgi def
vesicles stops there from er and sorts / repackeges then sends
mitocontria
energy change from atp to sugars
centriole
puts new genetic material into each cell and helps with cell division
vacuoles
water stored
cell wall
provides structure
chloroplast
photosynthisis
cytoplasm
help with chem reactions
what is the microscope fov calculation?
it is ocular x objective
Manipulated/Independent variable:
The one thing that is changed during an experiment
Responding/Dependent variable
measured/observed which is used to determine the influence
Controlled variables
factors that are held constant (same)
Pros of light microscope
Inexpensive
Transportable
Small in size
Laser Scanning Microscope
Computer generates 3D image
Transmission/ tunnel scanning microscope
Allows scientists to see at the atomic level
Converting from millimetres (mm) to micrometres (µm)
you times by 1000
what is the least objective lens to highest
4x
10x
40x
