The basic unit of biological organization, made of protoplasm and a membrane.

The fluid medium inside a cell, surrounded by the plasma membrane.

The protoplasm found inside the nucleus of a cell.

The protoplasm outside the nucleus, containing organelles and nutrients.

States that cells are the basic units of life, all organisms contain cells, and cells arise from existing cells.

A double phospholipid layer with embedded proteins that controls entry and exit of substances.

Describes the cell membrane structure as a mosaic of components that allows fluid movement.

A mixture where clumps of molecules are suspended in a fluid medium, distinct from solutions.

Short, hair-like structures that aid in cell movement and material transport.

A long, whip-like structure that propels cells, like sperm.

Plant cell organelles that perform photosynthesis using chlorophyll.

The process of converting light energy into chemical energy (food).

Plastids containing pigments that give fruits and flowers their colors.

Colorless plastids in plants that store food like starch.

A semirigid structure surrounding plant cells, made of cellulose.

A polysaccharide that forms the structural component of plant cell walls.

Compounds that dissolve in water; includes ionic salts.

Compounds that do not dissolve in water; includes fats and proteins.

Control center of the cell, surrounded by a double membrane.

Threads of nucleic acids in the nucleoplasm, visible as chromosomes during division.

Powerhouses of the cell, site of ATP production in aerobic respiration.

Inner folds of the mitochondrion that increase surface area for respiration.

Cell structures containing digestive enzymes; digest waste and old organelles.

Complex system of membranes involved in protein synthesis; can be rough or smooth.
