Every plant cell is the product of a biological merger billions of years ago. Chloroplasts are key structures in plants and algae that capture sunlight, but originally they were free-living bacteria ...

By snatching chloroplasts from algae, animals called sacoglossans produce their own energy through photosynthesis ...

A new study from the University of Helsinki reveals how plant mitochondria draw molecular oxygen away from chloroplasts, an interaction not previously documented. The discovery sheds new light on how ...

Plants constantly juggle oxygen inside their cells, but scientists have now discovered a surprising twist in how that balance works. Researchers at the University of Helsinki found that ...

Before I retired, I taught science to fourth graders in Midland’s gifted and talented program. As a scientist myself, I wanted my students to love science as I knew it: asking and answering questions ...

THE low-light intensity movement of the Mougeotia chloroplast (movement from profile to face position) can be induced by short irradiations with red light and occurs in a dark period of about 30 min ...

Oxygenic photosynthesis, a cornerstone of terrestrial and aquatic life, has long been associated with the absorption of visible light by chlorophyll a and ...

How do plants adapt to drought and heat? New studies on plants of the Canary Islands show that adaptation is not determined by a single character but by the interaction of entire sets of characters.

Plant responses to light are multiple. Light is an energy source, converted to sugars by photosynthesis. It is also a signal sensed by specific photoreceptors for red, blue and UV-B radiation. Absence ...

The species’ melanosomes—tiny, pigment-filled structures inside hair cells—are hollow, a trait never before seen in mammals ...

Microscopic ocean algae produce a huge share of Earth’s oxygen—but they need iron to do it. New field research shows that when iron is scarce, phytoplankton waste energy and photosynthesis falters.
