Atom molecule organelle cell (unicellular/multicellular) tissue organ system- organism- population community ecosystem- biome. Living things = organisms [virus not cells not living things], made of cells. Atoms we"re made of = chnops (e. g. po4-) Molecules (bio) : group of atoms in a specific structure giving a specific function. Organelle : structure inside a cell, w/ specific function (e. g. chloroplast) Cells : basic units of life: unicellular organisms = one cell (e. g. bacteria, paramecium, multicellular organisms. Tissues : group of similar cells (epiderm of skin) Organ : body part w/ a specific function, composed of different tissues (e. g. skin, stomach. System : group of organs w/ a general similar function (digestive system, excretory system [urine], respiratory system and circulatory system) Biological species : members having potential of reproduction, which kids are viable and fertile offspring. Populations = same specie"s members interacting with each other (e. g. mtl"s squirrels vs. south shore"s squirrels)
