National 5 Cell structure The functions of cell organelles Cells are microscopic building blocks of unicellular and multicellular living organisms.

Expansin's action has puzzling implications for plant cell-wall structure. The recent explosion of gene sequences and expression data has given new hints of additional biological functions for ...

These walls consist mainly of cellulose, noncellulosic polysaccharides and lignin, in proportions that depend upon the specific functions of the cell and its stage of development.

The secret of how fibre shapes the structure of plant cell walls has been revealed, with potentially wide-ranging applications ranging from nutrition and health to agriculture.

1. The structural features of cell walls in apical meristems were investigated, and the methods of analysis are described. Particular attention is given to the orientation of the cellulosic component ...

The cell-wall structure of the red alga Rhodymenia palmata has been examined by the methods of X-ray diffraction analysis and electron microscopy, including ultra-thin sectioning.
