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 ...

This basic structure of a plant cell is shown below - the same plant cell, as viewed with the light microscope, and with a transmission electron microscope. Figure caption, A generalised plant cell ...

Cells are the building blocks of life, and they come in various shapes and sizes. All living organisms are made up of cells and these cells have various similarities and differences. They are ...

Plants do not have a heart, blood or a circulation system, but they do need a transport system to move food, water and minerals around. The absorbed water is transported through the roots to the rest ...

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 ...

At first glance, plants may seem passive – but beneath their stillness lies a world of complexity and constant activity.

While prokaryotic cells do not have membrane-bound structures, they do have distinct cellular regions (Figure 1). In prokaryotic cells, DNA bundles together in a region called the nucleoid. Primitive ...
