Definitions
What is the motion of cytoplasm in a cell that results in a coordinated movement of the cell’s contents?
Cytoplasmic streaming
What is an organelle that contains its own DNA?
Mitochondria
What is is the movement of particles from areas of greater concentration to areas of lesser concentration?
Diffusion
What is the site of photosynthesis?
Chloroplasts
What is a solution in which the concentration of solutes is lower relative to another solution?
Hypotonic solution
What occurs when the cell releases the protein into the extracellular fluid?
secretion
What kind of cell has cell membranes, cytoplasm, ribosomes, lack a nucleus, and grow and reproduce?
Prokaryotic cells
What is the rupturing of a cell due to excess internal pressure?
Cytolysis
What are the are the digestive organelles that also serve to break up dead cell material?
Lysosomes
What would NOT work and cause Diffusion and osmosis to continue?
Mitochondria; passive transport
What kind of active transport that requires the cell to expend energy?
Endocytosis
What is the endocytic process by which a cell engulfs large, solid particles or cells?
Phagocytosis
What are membrane-bounded “sacs” that transport large molecules through cell membranes ?
Endocytic vesicles
What moves molecules agains their concentration gradient and require energy input?
Active transport
What is the name of these statements?
Cell Theory
What is the collapse of a walled cell’s cytoplasm due to a lack of water?
Plasmolysis
Where is the site of protein synthesis?
Ribosomes
What is the name of: diffusion, facilitated diffusion, and osmosis. All three types move molecules with their concentration gradient (from areas of high concentration to areas of low concentration) and so do not require energy input?
Passive transport
Who observed many cells and organisms under the microscope but he DID NOT contribute to the cell theory?
Van Leewenhoke
