cells and transportation Flashcards
Robert Hooke
Discovered and named cells
Anton Van Leevonhek
Made a more power full microscope and looked at living cell
Matthias Shilleden
propose that all plants are made of cells
Theodore Schwan
concluded all animal are made from cells
Rudolph Vichow
All cells came from preexisting cells
photosynthesis
converts solar energy into usable chemical energy
cellular respiration
chemical reactions that create usable energy for the cell while creating ATP
Equilibrium
a state of balance and stability
Homeostasis
maintaining the same state
ATP
high energy molecules
Golgi body
closely layered membranes sacs that packs and ships material throughout the cell
endoplasmic reticulum
help with intercelluar transport and the storage and synthesis materials and breaks down drugs and alcohols
lysosome
breaks down damage and worn down parts and defends the cell from bacteria and viruses (only animal)
ribosomes
site of protein synthesis
vacouole
Storage of water, food molecules, ions, and enzymes
cell wall
provides protection and structure
cilia
flagella
both provide help with movement
small hairs/or long wip like tail
why are prokaryotes smaller than eukaryotes
eukaryotea are more complex and are normal a port of a muticellural oragmism and prokaroes arent
where DNA found
nucleus/ nucleoid
cell membrane function
control what exits and enters
sperate one cell from another
maintan homoesisais
cell membrane parts
phospholipid bilayer - keeps a barrier
hydrophicl head - loves
hydrphoci - hatse
cholesterol - helps with fluidity allows stuff to move where it needs
proteins - helps with transporting materials
passive transport
high to low
no enegry
type of passive transport
osmosis - diffuion of water
diffusion- movement of materials from high to low concentration
facilitated diffusion - requaris proteins for lager molecules
active transport
requaris energy ATP
low to high consttraion
