Plant cells without walls, known as protoplasts, are very fragile, and it has been difficult to keep them alive under a ...

Imaging wall-less plant cells every six minutes for 24 hours revealed how the cells build their protective barriers.

Bordered pits are cavities in the thick secondary cell walls of both vessels and tracheids that are essential components in the water-transport system of higher plants. The pit membrane ...

The cells that make up the walls of the finest of all lymphatic vessels have a lobate, oak leaf-like shape that makes them particularly resilient to changes in fluid volume. A similar cell shape also ...

In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and ...

In a groundbreaking study on the synthesis of cellulose—a major constituent of all plant cell walls—a team of Rutgers University-New Brunswick researchers have captured images of the ...

A similar cell shape also supports mechanical stability in plants. The cells that make up the walls of the finest of all lymphatic vessels have a lobate, oak leaf-like shape that makes them ...
