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 ...

To get to the places where they are needed, immune cells not only squeeze through tiny pores. They even overcome wall-like barriers of tightly packed cells. Scientists have now discovered that cell ...

One of the most fundamental differences between animal and plant cells is the cell wall—a rigid structure surrounding the plant cells. The cell wall provides strength and structural support, but it ...

In a groundbreaking study on the synthesis of cellulose -- a major constituent of all plant cell walls -- a team has captured images of the microscopic process of cell-wall building continuously over ...

To communicate with its neighbors, animal cells use gap junctions which are symplasmic connections through which molecules can diffuse from one cell to another. In higher plants, the communication ...
