Parts of the Cell
Nuclear Envelope
separates nucleus from cytoplasm
hypertonic
having a higher concentration of solute than another solution
Smooth vs Rough ER
smooth - smooth surface, lipids, steroid, hormone production, dilated, closer to cell membrane
system chart
Kilo, hecto, deca, base, deci, centi, milli, nano, pico, micro
(King Henry Died Monday Drinking Chocolate Milk X X Maybe
Metric bases
Length - distance; meters
mass - amount of matter; gram
volume - amount of space; liters
Nuclear Pore
regulates movement of molecules
exocytosis
process of exporting proteins from a cell by a vesicle fusing with the plasma membrane
Unique organelles in plant cells
rigid cell walls, large central vacuole, chloroplasts (autotrophs)
Scientific method steps
identify problem, observation, form hypothesis, conduct experiment, collect data, form conclusion
liquid volume relationship
1cm3 water = 1 mL water = 1g water
nucleolus
makes ribosomes
endocytosis
active process in which a cell forms internal vesicles by invaginating its plasma membrane, allowing the absorption of various molecules and macromolecules from the extracellular fluid.
Unique organelles in animal cells
Centrioles/centrosomes, lysosomes
graphs must have..
title, scale, legend, labels for axes, data
different parts of the nucleus
nuclear envelope, nucleoplasm, nucleolus, chromatin, nuclear lamin, nuclear pores
Plasma membrane
thin outer boundary of a cell that regulates the traffic of chemicals between the cell and its surroundings
phospholipid
a group of polar lipids that consist of two fatty acids, a glycerol unit and a phosphate group which is esterified to an organic molecule (X) such as choline, ethanolamine, inositol, etc.
how do solutes/solvents move in different parts of passive transport
diffusion - solutes move high to low until even
osmosis - solvents move high to low until even
types of graphs
line - 2 quantitative
base - two different groups
role of microtubules
shape, movement, organelle transport, division, placement, muscle contraction
cytoskeleton
cell made up of microtubules, actin filaments, and intermediate filaments; shape and organization
concentration gradient
difference in the concentration of a substance between two areas
endocytosis - molecules in
exocytosis - molecules out
where does each variable go on a graph
independant - x
dependant - y
role of microfilaments
structure, movement, intracellular transport, division, placement, muscle contraction
