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 ...

A new method developed by Penn State biologists allows them to turn stripped-down plant cells into other types of cells, ...

Scientists reveal new plant cell walls can have significantly different mechanical properties compared to surrounding parental cell walls, enabling cells to change their local shape and influence the ...

The composition of an organism’s cell wall is the fourth characteristic used to classify an alga. Diatoms are unique as their cell wall is made of silica. The intricate designs within their silica ...
