Cell Theory
This scientist first discovered and named cells after observing cork under a microscope.
Who is Robert Hooke?
This cell structure regulates which particles enter and leave the cell.
What is the plasma membrane?
This type of transport moves particles without requiring energy from the cell.
What is passive transport?
This type of transport requires energy from the cell.
What is active transport?
This is the term for a solution that has less solute than another
What is Hypotonic?
This scientist stated that all cells come from other living cells.
Who is Rudolf Virchow?
These parts of phospholipids are attracted to water.
What are the polar phosphate heads?
This process is the movement of particles from an area of high concentration to an area of low concentration.
What is diffusion?
These use proteins to move molecules up a concentration Gradient
What are protein pumps?
This is the term for when a solution has more solute than another
What is Hypertonic?
These three scientists made the main contributions toward the development of cell theory.
Who are Schleiden, Schwann, and Virchow?
These parts of phospholipids are nonpolar and are repelled by water.
What are the fatty acid tails?
This process is the movement of water across a selectively permeable membrane.
What is osmosis?
This process brings materials into a cell by enclosing them in a membrane-bound vesicle.
What is endocytosis?
This is the term for when two solutions have equal amounts of solutes
What is isotonic
According to cell theory, all organisms are composed of these basic structures.
What are cells?
This substance is found in many cell membranes and helps provide support and stability.
What is cholesterol?
This type of passive transport uses channel or carrier proteins to help particles cross the plasma membrane.
What is facilitated diffusion?
This form of endocytosis brings solid materials into a cell,
What is phagocytosis?
This happens when a blood cell is put in a hypotonic solution.
What is it bursts?
This is the first principle of cell theory.
What is cells are the basic unit of structure and function?
This difference distinguishes plant cells from animal cells: plant cells have a cellulose structure that animal cells lack.
What is a cell wall?
These are the three forms of Passive Transport.
What are diffusion, osmosis, and facilitated diffusion?
This process releases cell products or wastes outside the cell when a vesicle fuses with the plasma membrane.
What is exocytosis?
This happens when a blood cell is put in a hypertonic solution.
What is it shrivels?
