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

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.

Our results indicate that modifications of cell wall structure and composition leading to e.g. loss of cell adhesion, can affect plant gas exchange independently of cuticle synthesis and guard cell ...

The multilayered nature of cell wall structure varied considerably between individual cells and was not exclusively related to the cell wall thickness. Nevertheless, fibres at the periphery of the ...

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.

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.
