(All Terms Come From Google)

TermDefinition
Homeostasis the tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes
Movement an act of changing physical location or position or of having this changed
Respiration the action of breathing
Growth the process of increasing in physical size
Adaptation the action or process of adapting or being adapted
Metabolism the chemical processes that occur within a living organism in order to maintain life
Excretion the process of eliminating or expelling waste matter
Reproduction the action or process of making a copy of something
Cilia plural form of cilium (goo.gl/NaFcAl)
Pseudopod another term for pseudopodium (a temporary protrusion of the surface of an amoeboid cell for movement and feeding)
Flagella a slender threadlike structure, especially a microscopic whiplike appendage that enables many protozoa, bacteria, spermatozoa, etc., to swim
Eyespot a light-sensitive pigmented spot on the bodies of invertebrate animals such as flatworms, starfishes, and microscopic crustaceans, and also in some unicellular organisms
Photosynthesis the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct
Chlorophyll a green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis. Its molecule contains a magnesium atom held in a porphyrin ring
Colony a community of animals or plants of one kind living close together or forming a physically connected structure
Oral Groove / Gullet Paramecia feed on microorganisms like bacteria, algae, and yeasts. To gather food, it uses its cilia to sweep prey organisms, along with some water, through the oral groove, and into the mouth opening... (en.wikipedia.org/wiki/Paramecium)
Autotroph An autotroph or producer, is an organism that produces complex organic compounds from simple substances present in its surroundings, generally using energy from light or inorganic chemical reactions
Heterotroph A heterotroph is an organism that cannot fix carbon from inorganic sources but uses organic carbon for growth
Cell Membrane the semipermeable membrane surrounding the cytoplasm of a cell
Cell Wall a rigid layer of polysaccharides lying outside the plasma membrane of the cells of plants, fungi, and bacteria. In the algae and higher plants, it consists mainly of cellulose
Nucleus the central and most important part of an object, movement, or group, forming the basis for its activity and growth; a dense organelle present in most eukaryotic cells, typically a single rounded structure... (goo.gl/2Q1uP7)
Chloroplasts a plastid that contains chlorophyll and in which photosynthesis takes place
Mitochondria an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. It has a double membrane, the inner layer being folded inward to form layers (cristae)
Vacuoles a space or vesicle within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid; a small cavity or space in tissue, especially in nervous tissue as the result of disease
Euglena A genus of single-celled flagellate Eukaryotes. It is the best known and most widely studied member of the class Euglenoidea, a diverse group containing some 54 genera and at least 800 species (g.co/kgs/uHplVu)
Amoeba A type of cell or organism which has the ability to alter its shape, primarily by extending and retracting pseudopods. Amoebae do not form a single taxonomic group, but are found in every major lineage of eukaryotic organisms (g.co/kgs/AYBl5T)
Paramecium A genus of unicellular ciliates, commonly studied as a representative of the ciliate group. Paramecia are widespread in freshwater, brackish, and marine environments and are often very abundant in stagnant basins and ponds (g.co/kgs/XSIun8)
"Globe Algae" (Volvox) A polyphyletic genus of chlorophyte green algae in the family Volvocaceae. It forms spherical colonies of up to 50,000 cells. They live in a variety of freshwater habitats, and were first reported by Antonie van Leeuwenhoek in 1700 (g.co/kgs/co8e1I)
