CELLULAR TRANSPORT Crossword

Diffusion of water through a selectively permeable membrane
Process by which particles tend to move from an area where they are more concentrated to an area where they are less concentrated
The process of diffusion in which molecules pass across the membrane through cell membrane channels
The movement of materials against a concentration gradient. REQUIRES ENERGY.
ny imbalance in concentration. Moving down a gradient means that the particle is trying to be evenly distributed everywhere, like dropping food coloring in water.
movement of ions and other atomic or molecular substances across cell membranes without need of energy input
The membrane of the vesicle or vacuole surrounding the material fuses with the cell membrane, forcing the contents out of the cell. The removal of water by means of a contractile vacuole is one example of this type of active transport
The process of taking material into the cell by means of infoldings, or pockets, of the cell membrane. Large molecules, clumps of food, and even whole cells can be taken up in this way.
The taking up of liquid by the cell. Tiny pockets form along the cell membrane, fill with liquid, and pinch off to form vacuoles
Type of endocytosis in which extensions of cytoplasm surround a particle and package it within a food vacuole. The cell then engulfs it. White blood cells use this method to remove damaged or foreign cells and destroy them
Outside of the cell
Inside of the cell
When comparing two solutions, the solution with the LESSER concentration of solutes
When comparing two solutions, the solution with the GREATER concentration of solute
When the concentration of two solutions is the same
Allowing liquids or gasses to pass through
Not allowing liquid or gas to pass through
Property of biological membranes that allows some substances to pass across it while others cannot, also called semi-permeable membrane
A double layered sheet called a lipid bilayer gives cell membranes a flexible structure that forms a strong barrier between the cell and its surroundings. Include fatty acid portions that have hydrophilic heads and hydrophobic tails.
Because so many different types of molecules make up the cell membrane, scientists describe the cell membrane as a fluid mosaic. (Fluid because the molecules move along the membrane and mosaic based off of the type of art that involves putting bits and pieces of different colors or materials together
