Cell Transportation

Cellulr transportati

QuestionAnswer
What is a solution Liquid mixture consisting of a solute and a solvent
What is a solute The substance that is being dissolved
Solvent The substance that is doing the dissolving
What does semi-permeable mean It means only certain substances are allowed to pass through
What are the three types of transport Active, Passive, and Bulk transport
What are some characteristics of passive transport -No energy -Diffusion -Osmosis -With concentration gradient
What are some characteristics of Active transport -Requires energy - Against concentration gradient
What is diffusion When partials move to a high contraction to a low concentration
What are some factors that affect diffusion Temperature, Pressure, & Concentration (As they go up, the rate will also)
What is Osmosis Movement of water across a cell membrane
Does water always move toward the higher or lower concentration of solute particles? Higher
What are the three types of solutions -Isotonic -Hypotonic -Hypertonic
What is Isotonic Solutes inside = solutes outside
What is Hypotonic Solutes are higher inside the cell than outside (water flows in, cells may burst)
What is Hypertonic Solutes are higher outside the cell than inside (water flows outside the cell, cell shrinks)
What is a turgor plant cell It's when a plant cell fills with water and press against the cell wall making the cells rigid
What does turgid mean Plump/Full
What does Flaccid water lost/dehydrated
What is a Contractillie Vacuole It's a structure in protists that collect and expels excess water out of the cell to prevent the cell from exploding
What is Facilitated diffusion A process that occurs when molecules move from an high area of concentration to a low with the aid of proteins
What is a channel protein A protein that allows the transport of specific substances across a cell membrane.
What is bulk transport Is used when molocules are too large to be moved by channel protiens
What is Endocytosis Movement into a cell by forming a vesicle
What is Exocytosis Movement out of a cell by releasing the contents of a vesicle
What is Pinocytosis Movement of large volumes of solution with dissolved solutes in or out the cell ("Cell drinking")
What is Phagocytes Movement of large particles into or out of the cell ("Cell eating")
What are some examples of Bulk transport Pinocytosis Phagocytes Exocytosis Endocytosis
What are the three parts of the cell theory (1) All living things are made up of cells,. (2) Cells are the smallest units (or most basic building blocks) of life. (3) All cells come from preexisting cells through the process of cell division
What is Homeostasis? I'ts maintaining a stable internal environment even though external conditions change
What are the to types of cells Prokaryotic and Eukaryotas
What are Prokaryotic cells Simple cells that have no membrane bound organelles or nucleus
What are Eukaryota cells Cells that have membrane bound organelles and nucleus
What is a protein pump? A type of membrane protein that requires energy in form of ATP to move molecules across the cellular membrane
What is a Vesicle "Mail men," small membrane bound sacs that transport materials around cell and to cell membrane
What is a Cytoskeleton A cellular skeleton made of protein micro-tubules and micro-filaments.
Where does water move in osmosis A high concentration of water to a low concentration of water
