Plants droop and shed their leaves when parched, but with a splash of water, their stems regain strength and their leaves ...

Plant cells have several structures not found in other eukaryotes. In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls ...

A new tool could make it easier to study scarce plant molecules. Researchers have developed so-called microbial cell factories -- using E. coli and yeast -- to produce a special class of plant ...

Vein arrangement, density ... which are outgrowths produced by living plant cells surrounding a vessel to seal it off after wounding or pathogen invasion (Figure 8). Abiotic factors can be ...

This interaction affects how the rice plant's vascular system develops. Researchers also discovered that in the mutant plants, the solid veins were filled with different types of cells ...

they hypothesized that the plant's vein network could serve as a scaffold for growing human heart tissue. The process began by stripping spinach leaves off their cells, and then turning them ...
