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

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 ...

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

The basic structure of a plant cell is shown below – the same plant cell, as viewed with the light microscope, and with the transmission electron microscope. Animal and plant cells have certain ...

Every time the temperature drops, a cloud passes overhead, or the sun sets, a plant makes a choice: Keep its microscopic ...

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 microscopic ...

Purdue University scientists have discovered a key mechanism that regulates how plants develop chloroplasts, essential ...

They therefore support the plant. Dissolved sugars and amino acids can be transported both up and down the stem. Companion cells, adjacent to the sieve tubes provide energy required to transport ...
