	Side A	Side B
1	lack nuclei and membrane-bound organelles; genetic material is not bound by a nuclear...	Prokaryotic Cells
2	have a membrane-bound nucleus and organelles	Eukaryotic Cells
3	Single-celled	Unicellular
4	Clusters of Cells	Aggregates
5	Clusters composed of a consistent and predictable number of cells	Colonies
6	have no physiological connections, but maintain a predictable multicellularstructure	Simple Colonies
7	Have physiological connections and specialization of groups of cells	Complex Colonies
8	have large numbers of cells w/ specialized structure and no one cell can exist by itself	Multicellular
9	Unicellular organisms may be _______(photosynthetic) or (deriving food from other organism)	Autotrophicheterotrophic
10	Part of an amoeba?	Cell membraneEctoplasmEndoplasmNucleusContractile vacuolesFood vacuoles:Pseudopodia
11	Ectoplasm -	The thin, transparent layer of cytoplasm directly beneath the cell membrane.
12	Endoplasm -	The granular cytoplasm containing the cell organelles.
13	Contractile Vacuoles -	gradually enlarge as they fill w/ excess water; serve as an excretory fxn
14	Food vacuoles -	contain undigested food particles
15	Pseudopodia -	fingerlike projections of the cytoplasm; used forlocomotion and phagocytosis
16	Flagella -	Used for locomotion
17	 The cells always occur in groups of from four to eight cells and they are permanentlyunited	Simple colonies
18	The size of the cell groupings is random and there are no permanent connections btwn cells	Aggregates
19	 Are permanently united and some cells are specialized for reproduction	Complex colonies
20	Daughter colonies -	smaller spheres within the larger colony; producedasexually
21	Cytoplasmic strands -	form connections bwn adjacent cells
22	Are composed of groups of specialized cells, called tissues, that together perform particular fxns...	Multicellular organisms
