Cells and Virus

Across
Rigid structure that gives protection, support, and shape to cells in plants, algae, fungi, and bacteria
Movement of dissolved molecules in a fluid or gas from a region of higher concentration to a region of lower concentration (with the concentration gradient)
Organelle composed of numerous membranes that are used to convert solar energy into chemical energy; site of photosynthesis; found in plant cells
Energy requiring movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration (against the concentration gradient)
Basic unit of life- Every living thing is made up of _____
Difference in the concentration of a substance from one location to another (in this case across a cell membrane)
Regulation nd maintenance of constant internal condition in an organism; equilibrium
Organelle composed of a double membrane (nuclear membrane) that acts as the storehouse for most of a cell's DNA
Infectious particle made only of a strand of either DNA or RNA surrounded by a protein coat; NOT a living organism
Diffusion (movement) of water molecules across a semi-permeable membrane from an area of high water concentration to an area of lower water concentration (with the concentration gradient)
A living cell in which a virus uses for reproduction and multiplies
Bean-shaped organelle that supplies energy to the cell; site of cellular respiration-makes ATP energy! (aka powerhouse of the cell!)
Down
Release of substances out of a cell by the fusion of a vesicle with the cell membrane
Double layer of phosphoLIPIDS that forms a boundary between a cell and the surrounding enviroment and controls the passage of materials into and out of a cell
One of two methods of virus reproduction: A method by which a virus can replicate its DNA using a host cell, causing the cell to burst or LYSE; Quick onset of symptoms
Diffusion (movement) of molecules assisted by protein channels across a cell membrane (with the concentration gradient)
Cell that has a nucleus and other membrane bound organelles
Movement of molecules across the cell membrane without energy input from the cell; does not require energy
One of two methods of virus reproduction: A method by which a virus can replicate its DNA using a host cell, usually the virus lays dormant for some time (no symptoms)
Uptake of a slid particle into a cell by engulfing the particle (see endocytosis)
Uptake of liquid or large molecules into a cell by inward folding of the cell membrane
Substance that stimulates an immune response, producing acquired immunity without illness or infection
Membrane bound structure that is specialized to preform a distinct/specific process within a cell
