Card Set Information
Bio 101 cpt 456
Cell Plasma Membrane
Composed of fluid-like phospholipid bilayer, proteins, cholesterol and glycoproteins.
Outside of cell membrane in some organisms; composed of carbohydrates (cellulose or chitin) or carbohydrate derivative (peptidoglycan)
Material outside nucleus
1. site for metabolic activity
: solutions with dissolved substances such as glucose, CO2, O2, etc.
: Membranebound subunits of cells with specialized functions.
Supportive and metabolic structure composed of microtubules, microfilaments, and intermediate filaments.
Simpler cellular organization with no nucleus or other membrane-bound organelles.
Comples cellular organization
Membrane of Eukaryotic cells
Bound organelles including nucleus, nuceolus, rough endoplasmaic reticulum, smooth endoplasmic reticulum, golgi apparatus, lysosome, peroxisome, chloroplast, chromoplast, leukoplast, mitochondrion, vacuole.
Contains DNA/chromosomes, control cellular activites via genes.
Located within Nucleus, site for ribosomes synthesis
Rough endoplasmic reticulum
With ribosomes, involved protein synthesis
Smooth endoplasmic reticulum
without ribosomes, involved primarily in lipid synthesis
Packaging center for molecules; carbohydrate synthesis
Contains hydrolytic enzymes for intracellular digestion
Involved in hydrogen peroxide synthesis and degradation
site of photosynthesis
non green pigment
General storage and space filling structure. Water cavity in cell
movement from an area of high to low concentration
Diffusion across a semi-permable membrane
Expelling materials from cell
More nutrons-remains neutral
Water has a positive charge
Different forms of an element
Unstable Isotopes / radio Isotopes
losing, gaining or sharing electrons
Maximum number is electrons
Inner shell 2
Stuff with mass
Weight & mass are synonyms
Atomic number is?
# of atoms in chart
# of protons in atom
Most outside shell, will never have more than 8 e-
Atom with a charge
Lost or gain of an eletron.
Same elements Different masses
Due to different number of of nuetrons
Two or more atoms linked together
Molecules with two or more different elements
such as water= H20
Strong e- shared in pairs.
2 atoms in a molecule
forms between oppositely charged area of covalent bonds
Polar molecules Water is polar
Non Covalent bonds
Two pairs double bond
Three triple bond covalent
Non covalent is much weaker
Hydrogen is the attraction between particular charges. Holds biological molecules together.
Of acid or base with is higher
Base is 14
Acid is 0
Neutral is 7
Sugars, starch (plants create and store), glycogen ( only humans), cellulose (can not be digested), chitin (shell of fish), energy sources
fats and oils
Weak acid or base
Accepts H+ when PH is low
Releases H+ when PH is high
Basic building blocks
Chains of monomers bonded together
where proteins are made
Made by gogli
Breaks down sugars
Universal storage modular
Can be used by any cell in any form
like rigatoni. stronger, more supportive
rope like, movements within cells
Kitchen twine...several tiny threads to create one strong thread
Holds cell walls together in bond, leak proof. nothing moves between cells
Hooks that go between cells but allow small molecules to pass between the cell walls such as water.
Channels that allow molecules to pass between cells.
channels within only plant cells
cause cells to talk and work long distances.
Travel in sap in plants.
are the building blocks of DNA
a velsicle moving towards the plasma membrane is an example of?
