For the first time, high-resolution time-lapse videos of tiny bits of living plants show how they assemble their protective cell walls, researchers report March 21 in Science Advances. The image ...

Heterogeneity in the polysaccharide constituents of plant cell walls has been recognized since the earliest chemical analyses of isolated wall preparations. Clear and dramatic differences in average ...

An international group of plant biologists has succeeded for the first time in visualizing how egg cells in plants divides unequally (asymmetric cell division) after being fertilized. The direction of ...

One of the most fundamental differences between animal and plant cells is the cell wall—a rigid structure surrounding the plant cells. The cell wall provides strength and structural support, but it ...

Vegetarians might not like hearing this, but plants have stem cells too. Like ours, these stem cells are undifferentiated and grow indefinitely in culture. And also like ours, they hold therapeutic ...

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 ...

When biologist Bruce Kohorn 25 years ago “accidentally” stumbled upon an unknown protein that turned out to be critical for cell growth and for protecting plants from pathogens, it set him off on a ...

Mutations drive evolution, but they can also be risky. New research led by plant biologists at the University of California, ...

Animal cells share some qualities with plant cells, but one key feature ours lack is a rigid cell wall. While this provides structure for plants, it’s also something scientists are increasingly ...
