Plant cells are surrounded by an intricately structured protective coat called the cell wall. It’s built of cellulose microfibrils intertwined with polysaccharides like hemicellulose or pectin. We ...

Imagine if our bodies could grow new organs throughout our entire lives. Plants do this constantly, thanks to tiny, powerful reservoirs of stem cells. But how do these cells know when to divide, and ...

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 ...

Plant cell walls, composed primarily of cellulose, hemicellulose and pectins, serve as dynamic structures that not only provide mechanical strength and protection but also regulate growth, ...

UNIVERSITY PARK, Pa. -- A plant cell wall's unique ability to expand without weakening or breaking--a quality required for plant growth--is due to the movement of its cellulose skeleton, according to ...

A cell wall is a fairly rigid layer surrounding a cell located outside of the plasma membrane that provides additional support and protection. They are found in bacteria, archaea, fungi, plants, and ...

Plant cell wall growth is typically described as a simple process, but researchers using a microscope that can resolve images on the nanoscale level have observed something more complex. A close-up ...

For a bacterial cell, the cell-wall is vital in determining the shape of the cell and to maintain its structural integrity. This is a unique feature of bacterial cells, and several antibiotics work by ...
