What is a compound light microscope used for?



StudySoup

Chapter 3 cell structure a function. 1x points to Ponder slide** What does cell theory tell us

o cell theory formulared after microscope in itoncentury 1. A cell is the basic unit of life TO ALL living things are made up of cells


What is transmission electron microscope used for?



• New cells come from preexisting cells

• Look different .ñ 100mm in diameter w/ width of human hair Don't forget about the age old question of What is evolution in simple terms?

red blood cell-do not have nucleus " Why are cells small?

consider the cell surface area to volume : - small cells have larger surface area


What is a scanning electron microscope used for?



We also discuss several other topics like What is the most common temperament?

Waliowo more nutrientoina was res to exit easier 6- there is a limit to how large cell can be

Eukaryono - Have a nucleus that houses DNA many membrane-bound organelles - incl animals, plants, fungi What do they have in common ?

plasma membane 1 surrounds a delineates cell 2. Regulates what enters dexits. 3. Phospholipid bilayer 4.) selectively permeable 5.) cell surface proteins A curoplasm that is semi fluid portion inside cell Don't forget about the age old question of Why do we treat children as a special audience?

contams organelles

• DNA know nucleus, plasma membrane, cytoplasm cutoskeleton

what does selectively permeable mean?

• membrane allows some things in, while keeping others

out

How do things move across plasma membrane?

1. diffusion 2 osmosis 3 facilitated transport 14 active transport 5. endocytosis a exocytosis Diffusion & osmosis?

random movement of morequires from higher to

a lower. Passive way. No energy 2. LOSmoshi - diffusion of H2O from higher to a lower

solute is unable to pass the membrane

How does tonicity change a cell i

• Isotonic solutions have equal amts of solute inside

doutside cell & this does not affect cell hypotonic & solutions have less solute than inside of

cell will burst hyperionic solutions have more solute than aside

of cell will shrink X SEA WATER Dehydratest what is facilitared transport? 3. facilitated transport Transport of molecules across

plasma membrane from a higher to a lower

via a protein carrier NO ENERGY NEEDED Heathieman ranspon: movement of molecules from a lower to

Lhigher Tusing ATP requires protein carrer

5. Endocytosis transports molecules or cells into the

cell via invagination of the plasma membrane to form a vesicle

ex: phagocytosis, pinocytosis, receptor mediated Neutrophil phagocytout 6. Exocytosis : transports molecules outside cell

Via fusion of a vesicle w plasma membrane
