9th Biology - Parts of Cell & Fluid Movement

describes a solution whose solute concentration is higher than the solute concentration inside the cell

describes a solution whose solute concentration is lower than the solute concentration inside the cell

a solution whose solute concentration is equal to the solute concentration inside the cell

the diffusion of water or another solvent from a more dilute solution to a more concentrated solution through a membrane that is permeable to the solvent

the transport of substances through a cell membrane along a concentration gradient with aid of carrier proteins

the movement of chemical substances usually across the cell membrane, against a concentration gradient; requires cell to use energy

the process by which a cell membrane surrounds a particle and encloses the particle in a vesicle to bring the particle into the cell

process in which extensions of cytoplasm surrounded and engulf large particles and take them into the cell

process by which a cell takes in liquid from the surrounding environment

the process by which a substance is released from the cell through a vesicle that transports the substance to the cell surface and then fuses with the membrane to let the substance out

an organism that produces its own nutrients from inorganic substances or from the environment instead of consuming other organisms

an organism that obtains organic food molecules by eating other organisms or their by-products and that cannot synthesize organic compounds form inorganic materials

particles of nucleic acids, proteins and in some cases lipids

a virus's protein coat

viruses that infect bacteria

virus enters the cell, makes copies to itself and causes the cell to burst

host cell makes copies of the cell indefinitely; a virus integrates its DNA into the DNA of the host cell and the viral genetic information replicates along with the host cell's DNA

the viral DNA that is embedded in the host's DNA

viruses that contain RNA as their genetic information

single-stranded RNA molecules that have no surrounding capsid

basic unit of all forms of life

the theory that states that all living things are made up of cells

an organism that consists of a single cell that does not have a nucleus of cell organelles

an organism made up of cells that have a nucleus enclosed by a membrane multiple chromosomes and mitotic cycle

one of the small bodies found in the cytoplasm of a cell and specialized to preform a specific function

the region of the cell within the membrane that includes the fluid, the cytoskeleton and all of the organelles except the nucleus

a cell organelle composed of RNA and protein; the sight of protein synthesis

in a eukaryotic cell, a membrane-bound organelle that contains the cells DNA and that has role in processes such as growth, metabolism and reproduction

a system of membranes that is found in a cell's cytoplasm and that assists in the production, processing and transport of proteins and in the production of lipids

cell organelle that helps make and package materials to be transported out of the cell

in eukaryotic cells, the cell organelle that is surrounded by two membranes and is the site for cellular respiration which produces ATP

on organelle found in plant and algae cells where photosynthesis occurs

a large cavity or sac that is found in plant cells or protozoans and that contains air or partially digested food

a phospholipid layer hat covers a cell's surface and acts as a barrier between the inside of the cell and the cell's environment

a rigid structure that surrounds the cells membrane and provides support to the cell; mostly found in plant cells but sometime found in bacteria

a cell organelle that contains digestive enzymes

a basic structure of a biological membrane; composed of two layers of phosopholipids

the mass of solute in a given volume of solution or mass/volume

the movement of particles from regions of higher density to regions of lower density

in chemistry the state in which a chemical reaction and the reverse chemical reaction occur at the same rate such as the concentrations of reactions and products do not changeEquilibrium
