Chapter 8 Cell Structure and Function Assessment

Front

Diffusion of water through a selectively permeable membrane.

Back

Osmosis is the process where water molecules move from an area of lower solute concentration to an area of higher solute concentration through a selectively permeable membrane.

Front

When the concentration of two solutions is the same.

Back

Isotonic refers to a solution where the concentration of solutes is equal on both sides of a membrane, resulting in no net movement of water.

Front

Cells that enclose their DNA in nuclei.

Back

Eukaryote is a type of cell that has a nucleus enclosed within membranes, distinguishing it from prokaryotic cells.

Front

Group of tissues that work together to perform closely related functions.

Back

An Organ is a structure made up of different types of tissues that work together to perform a specific function.

Front

Cells that do not enclose their DNA in nuclei.

Back

Prokaryote refers to a type of cell that lacks a membrane-bound nucleus and other organelles.

Front

The basic unit of life.

Back

Cell is the smallest structural and functional unit of an organism, which can exist independently or as part of a multicellular organism.

Front

The protective outer layer of a cell.

Back

Cell Membrane is a biological membrane that separates and protects the interior of all cells from the outside environment.

Front

The scientific study of cells.

Back

Cell Theory is a fundamental concept in biology that states that all living things are composed of cells, and that cells are the basic unit of life.

Front

The process by which cells maintain a stable internal environment.

Back

Homeostasis is the ability of an organism or cell to maintain internal equilibrium by adjusting its physiological processes.

Front

A structure within a cell that performs a specific function.

Back

Organelle is a specialized subunit within a cell that has a specific function, such as mitochondria or ribosomes.
