bio ch 7 Flashcards
what do you see through in a microscope
eye piece
which knob is the thick and which one is the thin one on a microscope
coarse is thick, fine is thin
What does the transmission electron microscope do
goes through specimen to see inside a cell
who was anton von Leeuwenhoek
made the first microscope and discovered microbes
what adjusts light in a microscope
diaphram
what holds the thing your looking at on a microscope
stage clips
what does scanning electron microsope do
electrons bounce of surface and magnifies the shape of cells
who was robert hooked
he came up with cells
who was robert brown
he discovered the nucleus
what did schlieden say:
what did schwann say:
plants are made of cells
animals are made of cells
what is the cell theory all three
- all iving things are made of cells
- cells are the basic unit of structure and function
3.cells came from prexising cells
what did rudolf virchow say
cells came from prexisiting cells
what is the differnece between prokaryot and eukaryotic cells.
prokaryot doesnt have a nucleus
what is the other thing besides nucleus that eukaryotic cells have
organelles
how is a plant cell different from animal cell
they have cell wall, chloroplasts, and a large vacuule(big space in the middle)
animals only have cell membrane and small vacuole
do amoebas have cell walls. why?
no,otherwise they couldnt change shape
what the cell membrane structure layers
bilipid layer
what is the membrane cell layer made of
phospholipid
what is the head end and tail end of the phospholipid
head is hydrophilic
tail is hydrophobic
is the head or the tail inside the lipid bilayer
the hydrophobic tail
where do things come out of in the membrane
the proteins
what are the nametage cells that say this cell belongs to me
carbohydrates
what are carbs mostly on
proteins and lipids(mostly proteins)
what info is on inside of nucleas
dna(in form of chromatin)
whats the dark structure in the nucleus
nucleolus
what is the nucleolus make
RNA
cytoskeleton
l. The cytoskeleton’s main function is structure and support for the cell,
whats the difference between microtubule and microfilaments
microtuble is hollow in the middle and a little larger and its like a zipline
microfilaments hold things in place structure
what are the storage containers in the cell
vacuoles
what is chloroplast
the organelle that is responsible for photosythesis
what is cytooplasm
Material inside the cell membrane–not including the nucleus
what is a vacuole
membrane bound organelles that can be found in both animals and plants
what is a ribosome
Material inside the cell membrane–not including the nucleus
vesicle
A small sac formed by a membrane and filled with liquid.
lysosome
breaks down and recycles cellular components,
where do ribosomes hang out
in the endoplasmic reticulum
when ribosomes are attached to endoplasmic reticulum its called…
rough er
what are all the foldings
primary secondary tertiary and quantenery foldings
where does the vesicle move to after being formed or whatever
the golgi appartus
say all the steps of the thing
- proteins are assembled or ribosomes
- proteins targeted for export to the cell membrane or to specialized locations within the cell complete their assemblies on ribosomes bound to the rough er
3.newly assembled proteins are carried from the rough endoplasmic reticulum to the Golgi apparatus in vesicles
4.the Golgi apparatusd further modifies proteins before sorting and packaging them in membrane-bound vesicles - vesicles from the Golgi apparatus are shipped to their final destination in or out of the cell.
