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 ...

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

Purdue University scientists have discovered a key mechanism that regulates how plants develop chloroplasts, essential structures responsible for the photosynthesis that sustains life on Earth by ...

Major steps forward in the use of plants for renewable materials, energy and for building construction could soon arise, thanks to a key advance in understanding the structure of wood. The step ...

Essentials of Biology is a non-majors general biology course without a laboratory. The topics that will be covered include biological molecules, cell structure and function, cellular metabolism, cell ...

The cell nucleus is the site of many important biological functions of the eukaryotic cell. These processes include transcription, replication, splicing and ribosome biogenesis. The effect of these ...

Human chromosomes behave in much the same way as those of rodents, primates, and other close evolutionary cousins. But researchers don’t know whether those similarities might extend to distantly ...
