BIOL 1406 Lab Test 2 Vocab

rigid cellulose box enclosing each plant cell

membranous structure in many plant cells that produces food by photosynthesis, contains chlorophyll

numerous short, hair-like structures projecting from the surface of some cells: coordinated wave-like motion produces movement of cell or materials on surface of cell

movement of cytoplasm w/in euk cells, generally a circular streaming around large sap vacuole

layer of cells that covers inner or outer surfaces of organs and cavities

have membrane bound organelles, ex animal, plant, fungi, protists

forms outer boundary of protoplasm; holds cell contents together and regulates passage of materials in and out of cell

membrane bound organelle that functions in carb metab of plant and algal cells; includes chloroplasts (photo) and leucoplasts (starch storage)

cells that contain no membrane bound organelles, includes bacteria and blue green algae

semifluid substance consisting mainly of water, proteins, lipids, carbs, inorganic salts and suspended organelles

large central chamber of plant cells holding water

hydrostatic pressure w/in a plant cell caused by pressure of contents against a rigid cell wall

movement of moles from low to high conc req energy

shrinkage of a red blood cell when place in a hypertonic sol

movement of moles from high to low w/o energy (passive)

active elimination of large materials

solution with higher solute concen than the cell, osmosis will occur with cell gaining water

solution having the same solute and solvent concen as the cell no osmosis

water higher to lower concen

movement that req no energy, osmosis

shrinkage of protoplasm in a plant cell, usually as a result of loss of water to a hypertonic environment

stiffness or rigidity of plant cells caused by cells gaining water and as result of the swelling press against the cell wall

plant pigments that abosorb energy from different parts of the light spectrum, may pass the energy on to chlorophyll for photo

purple, blue or dark red pigments found in some flowers, leaves

pigment found in beets, possibly a chemical defense against predators

accessory pigments of yellow or orange

conversion of glucose to pyruvic acid, there is a net gain of two ATP molecules

conversion of pyruvic acid to lactic acid,typicalof muscle cellswhen o2 is limiting

3 carbon product of glucose breakdown during glycolysis
