Growth and Morphogenesis in Plant Cells
- 1972 ----- color ----- 13 min ----- 16mm
- Using Nitella axillaris as an example, shows that cell elongation is an expansion process where high pressure serves as the driving force of growth and, at the same time, contributes to the rigidity of the plant. Elongated plant organs, such as stems and roots, grow as cylinders because their cells undergo directed expansion along the cell axis. This is achieved by circumferencial reinforcement with cellulose microfibrils; therefore, plant growth is a combination of turgor pressure and the special yielding qualities of the cell wall.
