THIS IS A BASIC REVIEW OF IMPORTANT BIOLOGY TERMS. IT IS NOT A SUBSITUTE FOR STUDYING, AND IT DOES NOT INCLUDE EVERYTHING ON THE FINAL.

Orgin of Species

written by Charles Darwin

DNA

Prokaryotic cells LACK

ACTG

Letters associated with DNA

Antibiotic resistent bacteria

Does not fall under Domain Eukarya

Unequal Reproductive Success

Darwin's inescapable conclusion

Properties associated with life

Example: order, regulation, reproduction, evolution, response to enviornment

Biology

study of life

Smallest unit of life

cell

Protista

kingdom where organisms are generally single-celled

Plants

encorporate energy into most ecosystems

Natural selection tends to act at the level of

Population

proton

positively charged particle

neutron

neutral particle of an atom

electron

negatively charged particle

atomic number

the number of protons in the nucleus of an atom

mass number

the number of protons plus the number of neutrons it contains

atom

basic unit of matter

2 forces causing chemical bonding

sharing of electrons, opposite electrical charges

ionic bond

a chemical bond in which one atom loses an electron to form a positive ion and the other atom gains to electron to form a negative ion, and the opposite charges cause them to combine

covalent bond

a bond formed when atoms share one or more pairs of electrons

Life giving qualities of water

Ice floating, temperture modification, cohesion of water

solution

a homogeneous mixture of two or more substances

solute

the dissolved substance in a solution

solvent

the substance in which the solute dissolves

organic compounds

contain carbon

organic chemistry

study of organic compounds

hydrocarbons

contain only carbon and hydrogen

hydrolysis

break with water

unsaturated

do not contain full amount of hydrogens

saturated

full amount of hydrogens

amino acids

make up polypeptides

light microscopes

use when specimen is alive

electron scanning microscope

beam of electrons resolve object

transmission electron microscope

use for looking at internal sctructures of cells

plasma membrane

regulates traffic of cell

phosphlipid bilayer

two layered membrane in cell

Not a part of endomembrane system

nucleus

stroma

thick fluid in chloroplast

grana

stacks of thykaloids in chloroplast

matrix

thick fluid in mitochondria

cristae

structure of mitochondria

energy

capacity to perform work

heat

describes motion of atoms and molecules

entropy

measure of disorder

enzyme inhibitors

substrate imposters

facilitated diffusion

transport proteins act as corriders in cell membrane

oxidation

loss of electrons in redox reaction

ATP synthase

allows H+ ions through during electron transport

stomata

tiny pores on underside of most leaves

thykaloid

single disk in granum

electromagnetic spectrum

full range of radiation

chlorophyll a

involved directly in light reactions

photon

fixed quantity of light energy

C3 plants

can't survive in aird enviornment
