A rigid structure that surrounds the cell in plants and fungi.

Limits expansion of the cell due to osmosis.

Commonly made of cellulose in plants and chitin in fungi.

Cell wall is rigid; cell membrane is flexible.

Cell walls are particularly prominent in mature cells.

The basic structural unit of all living organisms.

Living organisms that consist of only one cell.

Organisms made up of many cells working together.

Single-celled microorganisms that can be found everywhere.

Cells are considered the smallest unit of life that can function independently.

Mechanisms that force solutes through a membrane.

The process that allows materials to be transported across a membrane by merging sections of the membrane.

The process of excreting large particles by fusing vesicles with the cell membrane.

The process of engulfing large particles by enclosing them within the membrane.

The movement of substances into, out of, or within a cell.

Strong cell walls in plants that help them grow tall by providing structural support.

Plants have a rigid cell wall while animals do not, affecting their structure.

Support that enables plants to withstand pressure and grow tall.

The ability of plants to grow upwards due to rigid cell walls.

Cell walls that provide strength and toughness to plants.

A brittle, glue-like material that adds rigidity to cell walls.

Non-vascular plants that lack lignified cell walls.

Walls that contain lignin, providing strength and support.

Structures that provide support and protection to plant cells.

The set of life-sustaining chemical reactions in organisms.

Proteins that interact with or are part of biological membranes.

Proteins that are loosely attached to the outer or inner surface of the membrane.

The division of a cell into separate regions to enhance function.

Intermolecular forces that bind proteins to membranes through charge interactions.
