1. what functions do cells preform: reproduce, produce energy, remove waste, transport process
2. What structures/cellular components enable cellular functions?: nucleus, mitochondria, lysosomes, the
endoplasmic reticulum, and the Golgi apparatus. cell membrane
3. describe at least 4 cellular functions that are common to all cells and explain why these functions are essential
for life: 1-made up of cells with cell membranes 2-reproduce/replicate
3- evolution
4- information-interpret hereditary and enviormental information 5- enerygy use and
acquire
4. periodic table: A table that shows the elements, their atomic number, symbol, and average atomic mass;
mass-protons+neutrons atomic number-#of protons p=electrons
5. electron shell: An energy level representing the distance of an ele nucleus of an atom.
ctron from
-role in bond formation (empty valence shells bond) the
6. covalent bond: A chemical bond that involves sharing a pair of elect atoms in a molecule rons
!!stronger than ionic hydrogen bonds stronger than ionic bonds in between
water
7. ionic bond: A chemical bond resulting from the attraction between oppositely charged ions.
8. Hydrogen bonds: a weak bond between two molecules resulting from an elec- trostatic attraction between a proton
in one molecule and an electronegative atom in the other.
9. be abel to digram them between water molecules:
10.Electronegativity: A measure of the ability of an atom in a chemical compound to attract electrons
