This and That
The three main ideas of this are 1. All living things are made of cells, 2. Cells are the basic unit of structure and function, 3. All cells come from pre-existing cells.
What is Cell theory?
Site of photosynthesis
What are Chloroplasts?
The process that requires the cell to expend energy
What is active transport?
The motion of cytoplasm in a cell that results in a coordinated movement of the cell's contents.
What is cytoplasmic streaming?
The hydrophobic chains of a phospholipid in the cellular membrane.
What are fatty acid tails?
This colorless plastid found in plant cells that stores carbohydrates.
What is a leucoplast?
Powerhouse of the cell. Also contains it's own DNA and carries out the cellular process of respiration.
What is the mitochondria?
What is Endocytosis?
A solution in which the concentration of solutes is lower relative to another solution
What is a hypotonic solution?
The type of proteins that go through both layers of the phospholipid bilayer.
What are integral proteins?
Plastids that function in photosynthesis but contain red, orange, or yellow pigments.
What are chromoplasts?
Site of Protein Synthesis.
What are ribosomes?
The 3 types of passive transport.
What is diffusion, osmosis, and facilitated diffusion?
The endocytic process by which a cell engulfs large, solid particles or cells.
What is phagocytosis?
The hydrophilic portion of the phospholipid bilayer. These connected together make the interior and/or exterior of the plasma membrane.
What are phosphate heads?
Schwann, Schleiden, Virchow all made contributions to this.
What is the cell theory?
Digestive organelle that may also break up dead cell material
What are Lysosomes?
The reason passive transport does not require energy. The name for molecules moving from an area of high concentration to low concentration.
What is a concentration gradient?
Collapse of a walled cell's cytoplasm due to a lack of water.
What is Plasmolysis?
What's found only on the exterior of the cell membrane attached to either proteins or lipids.
What are carbohydrates?
After producing a protein, the function of the cell releasing the protein to the outside of the cell.
What is secretion?
Membrane-bounded "sac" that transports large molecules through the cell membrane
What are Endocytic vesicles?
The structures that cells use to move smaller molecules across the membrane against their concentration gradient during active transport.
What are pumps?
The rupturing of a cell due to excess internal pressure
What is cytolysis?
The hydrophobic molecule found in the middle of the membrane made of fatty acid rings.
What is cholesterol?
