A fundamental concept stating that all living things are made of cells, which are the basic units of life and come from pre-existing cells.

Cells without a nucleus or membrane-bound organelles, such as bacteria.

Cells that contain a nucleus and organelles, such as plants and animals.

Specialized structures within eukaryotic cells that perform specific functions necessary for life.

Cells are considered the smallest structural and functional units of living organisms.

The gel-like substance where organelles are suspended and many chemical reactions occur.

A flexible, double-layered structure that supports the cell and controls entry and exit of substances.

The spherical structure that contains the cell's genetic information on chromosomes.

Organelles known as the 'power plants' that generate energy through cellular respiration.

A network of tubes that transports materials such as proteins throughout the cell.

Organelles that collect, process, and secrete materials to be removed from the cell.

Fluid-filled sacs that store substances and help maintain internal fluid pressure.

A rigid outer layer found in plant cells that provides support and protection.

Organelles in plant cells that conduct photosynthesis to convert sunlight into energy.

Describes a membrane that allows certain substances to pass while blocking others.
