Plant cell walls, composed primarily of cellulose, hemicellulose and pectins, serve as dynamic structures that not only provide mechanical strength and protection but also regulate growth, ...

Humans rely on the arsenal of cells, molecules, and biochemical pathways of the immune system to defend the body when it's threatened by pathogens. But there are many different biological mechanisms ...

Plants are a rich and renewable source of compounds used in medicines, food ingredients, and cosmetics. Since growing an ...

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 ...

Similar to humans, plants have an immune system to help defend against parasites and other deleterious infections. The human body is interconnected with cell-to-cell communication to orchestrate an ...

Plants adapt their water consumption to environmental conditions by counting and calculating environmental stimuli with their guard cells. Plants control their water consumption via adjustable pores ...

As 2025 comes to a close, the editors at The Scientist asked researchers to reflect on the biggest breakthroughs in cell biology this year. They named advances in everything from embryo models for ...

A Northwestern Medicine study has shed light on one of the most intricate construction projects in biology: how cells build ...

Until now, cells dividing by mitosis were thought to grow round and then split into two identical, spherical daughter cells. New research has found that some cells are isomorphic, meaning they retain ...
