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 ...

Some eukaryotes consist of a single cell; but most single-celled creatures are made of simpler cells which lack obvious ...

Cells manage a wide range of functions in their tiny package — growing, moving, housekeeping, and so on — and most of those functions require energy. But how do cells get this energy in the first ...

The growth and metabolism of plants in response to different concentrations of tissue K is discussed in relation to current knowledge about the distribution and functions of this ion in plant cells.

The exocyst, an octameric tethering complex and effector of Rho and Rab GTPases, facilitates polarized secretion in yeast and animals. Recent evidence implicates three plant homologs of exocyst ...

Plants are active life-forms down to their very cells. Within seconds of light exposure, some plants' chloroplasts—the cellular organs that convert light to energy—will begin to scramble around and ...

Scientists have discovered a basis of communication in plant cells: The 'MICU' protein controls the calcium ion concentration in the cellular power stations. Using these chemical signatures, the ...

Scientists at Cold Spring Harbor Laboratory have cracked open the secrets of plant stem cells, mapping key genetic regulators in maize and Arabidopsis. By using single-cell RNA sequencing, they ...

Zinc is an essential nutrient found in a variety of plant and animal foods, along with supplements. It plays a key role in skin health, immune function, and cell growth and may protect against acne, ...
