what happens to water movement when a cell without a celll walls is placed in an isotonic solution, Water moves out of the cell causing it to shrivel., No net water movement across the plasma membrane., The cell gains water rapidly, swells, and bursts., Water moves randomly without affecting the cell, What is the effect of placing a cell in a hypertonic solution where the solute concentration is greater than that inside the cell, The cell swells and lyses., The cell remains in a normal shape., Cell may loses water, shrivel and probably die., Water flows rapidly into the cell., Which of the following describes what happens to a cell when placed in a hypotonic solution?, The cell loses water and shrivels., Cell gains water faster, swell and lyse (burst)., There is no net movement of water across themembrane., Water moves out of the cell at a steady rate., What kind of problems do hypertonic or hypotonic environments create for organisms?, Metabolic problems, Osmotic problems, Genetic problems, Structural problems, What is defined as "the control of solute concentrations and water balance, which is a necessary adaptation for life in such environments"?, Diffusion, Active transport, Osmoregulation, Phagocytosis, What organelle does the protist Paramecium use to act as apump to force water out?, Nucleus, Ribosome, Mitochondrion, Contractile vacuole, What happens to a plant cell when it is placed in a hypotonic solution until the plasma membrane is near to the wall?, The cell becomes flaccid, The cell is now turgid, The cell undergoes plasmolysis, The cell loses water completely, What happens to a plant cell and its surroundings when they are isotonic and there is no net movement of water into the cell?, The cell becomes turgid, The cell becomes flaccid, The cell undergoes plasmolysis, The plasma membrane pulls away from the wall, What is the usually lethal effect called when plant cells lose water in a hypertonic environment and the membrane pulls away from the cell wall?, Turgid, Flaccid, Osmoregulation, Plasmolysis, In facilitated diffusion, transport proteins speed the passive movement of molecules across the, Cell wall, Plasma membrane, Cytoplasm, Extracellular fluid, Transport proteins include Channel proteins and, Structural proteins, Receptor proteins, Carrier proteins, Enzymatic proteins, Channel proteins allow molecules or ions to diffuse very, Slowly, Quickly, Randomly, Indirectly
