TRANSCRIPT
Active Transport
• transport that requires a cell to expend its own energy to pump a molecule across the membrane. Movement of molecules from areas of low concentration to areas of high transportation
Endocytosis
• transport that occurs when the cell membrane encloses around the particle forming a pouch, the pouch is then draw into the cell, requires energy on behalf of the cell
Exocytosis
• transport that occurs when the cell memberane forms an internal pouch of large/multiple molecules and then releases them outside of the cell, requires energy on behalf of the cell
Facilitated Diffusion
• the transport of substances through a cell membrane along a concentration gradient with the aid of carrier proteins
Hypertonic Solution
• a situation that describes a solution when the concentration of solutes in solution is higher than inside the cell <OR> a term to describe a cell or solution that GAINS water
Isotonic Solution
• an adjective that describes a solution when the concentration of solutes in solution is the same as inside the cell <OR> a term to describe when a cell is equal to its surrounding solution regarding water concentration
Osmosis
• the diffusion of water (from a high conc. To a low conc.) across a cell membrane (selectively permeable membrane)
Hypotonic Solution
• a situation that describes a solution when the concentration of solutes in solution is lower than inside the cell <OR> a term to describe a cell or solution that LOSES water
Passive Transport
• transport that does not require the cell's chemical energy to move molecules across the membrane
Anaphase
• Third phase of mitosis in which sister chromatids are pulled to opposite sides of the cell
Cell Cycle
• The stages that take place between the time a eukaryotic cell divides and the time the daughter cells divide. (stages of growth, preparation, and division (Interphase and Mitosis)
Prophase
• Nucleolus has disappeared, and duplicated chromosomes are visible. Centrosomes begin moving apart, and spindle is in process of forming.
Metaphase
• Second phase of mitosis, during which the chromosomes line up across the center of the cell
Telophase
• The fourth and final stage of mitosis, in which nuclei are forming and cytokinesis has typically begun.
Homeostasis
• the ability of an organism to self-adjust to maintain a balance of life functions in a changing environment
Diffusion
• the process by which molecules of a substance move from an area of high concentration of that substance to areas of lower concentration until they are evenly distributed about the container
