What is a defining feature of plant cells?

A defining feature of plant cells is the presence of a cell wall made of cellulose. This structural component provides strength and rigidity to the cell, allowing plants to maintain their shape and resist mechanical stress. The cell wall is unique to plant cells compared to animal cells, which do not have a cell wall. Additionally, the cell wall plays a crucial role in the regulation of water intake and the overall integrity of the plant.

While numerous other features differentiate plant cells from other cell types, the cellulose cell wall is particularly significant as it is integral to their functionality and growth. It allows plants to grow tall and adapt to a variety of environments while providing a definite shape, contributing to the overall organization and structure of plant tissues.
