Cell Transportation Crossword Puzzle

QUESTIONS LIST:

• turgid : when plant cells are swollen with water.
• crenated : when animal cells have collapsed due to water loss.
• exocytosis : release of cellular substances as secretions from cells in membrane vesicles.
• osmosis : the movement of water molecules from a region of high water concentration to a region of low water concentration across a semi-permeable membrane.
• cell membrane : the thin skin surrounding the cytoplasm of every cells.
• plasmolysed : when plant cells have lost water due to osmosis.
• active transport : energy from cells is needed to move particles against a concentration gradient across its membrane.
• passive transport : no energy is required by the cell to move molecules across its membrane.
• hypotonic : the solution has a lower solute concentration than the cell.
• phospholipid : lipids found in all living cells and in the bilayers of cell membranes.
• phagocytosis : cell eating.
• endocytosis : incorporation of substances into a cell by phagocytosis or pinocytosis.
• osmotic pressure : a force driven by differences in solute concentrations that causes the net movement of water out of or into a cell.
• pinocytosis : cell drinking.
• water : this substance is free to move across the cell membrane unrestricted.
• diffusion : the passive movement of particles from a region of high concentration to a region of low concentration down a concentration gradient.
• diffusion : the passive movement of particles from a region of high concentration to a region of low concentration, down a concentration gradient or slope, over short distances.
• semipermeable : the cell membrane controls the movement of substances into and out of the cell allowing smaller molecules through, but stopping larger ones.
• isotonic : the concentration of solutes is the same inside and outside the cell.
• aquaporins : cells that contain water channel proteins that allow water to pass right through them.
