Hair grows because cells at the root divide and push it upward, like toothpaste squeezed from a tube. At least, this is what what we thought. However, new research claims this explanation is ...
JSTOR Daily: Cell wall-associated ROOT HAIR SPECIFIC 10, a proline-rich receptor-like kinase, is a negative modulator of Arabidopsis root hair growth
Plant cell growth is restricted by the cell wall, and cell wall dynamics act as signals for the cytoplasmic and nuclear events of cell growth. Among various receptor kinases, ROOT HAIR SPECIFIC 10 ...

Science Daily: Auxin signaling pathway controls root hair formation for nitrogen uptake
Root hairs represent a low-cost strategy to enhance nutrient uptake because they can significantly increase the nutrient-acquiring surface of plant roots. While primary and lateral roots are ...
Cell theory, developed in 1839 by Matthias Jakob Schleiden and Theodor Schwann, states that all organisms are composed of one or more cells, that cells are the fundamental unit of structure and function in all organisms, and that all cells come from pre-existing cells. Organisms are broadly grouped into eukaryotes and prokaryotes.
Cells consist of a variety of internal and external structures that perform specialized functions necessary for survival and reproduction. These components vary depending on whether the cell is prokaryotic or eukaryotic, and whether it belongs to a plant, animal, fungus, or protist.
All cells evolved from a common ancestor and use the same kinds of carbon-based molecules. Learn how cell function depends on a diverse group of nucleic acids, proteins, lipids, and sugars.
