cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size. What Is the Origin of Chloroplasts? Like mitochondria ...

A plant cell wall is arranged in layers and contains cellulose microfibrils, hemicellulose, pectin, lignin, and soluble protein. These components are organized into three major layers: the primary ...

In pure water, the cell contents (the cytoplasm and vacuole) push against the cell wall and the cell becomes turgid . Fully turgid cells support the stems of non-woody plants. In a very ...

Plant cells have a rigid cell structure. They are made up of a cell wall, cell membrane, cytoplasm, vacuole, nucleus, and chloroplasts. Plants feel firm because of their cellular walls.
