An international research team has uncovered a surprising way compartments within cells work together to defend themselves ...

For the first time, a plant specimen has been cryopreserved and placed into the San Diego Zoo Wildlife Alliance’s Frozen Zoo, a step scientists believe could help the endangered scrub oak species ...

If measured from beginning to end, the DNA in our cells is too long to fit into the cell's nucleus, explaining why it must be ...

'Thawed strawberries naturally become softer and juicier due to the breakdown of cell walls during freezing,' says Jason.

Plants produce a wide diversity of compounds. Broadly, these are separated into primary metabolites, which are necessary for ...

Scientists have gained an atomic-level view of plant cells, getting to know the metacaspase 9 enzyme in the process.

Three hundred and thirteen extracts from 136 Brazilian plant species belonging to 36 families were tested for their suppressive activity on phytohemaglutinin (PHA) stimulated proliferation of human ...

A light freeze is possible when air temperatures drop to 28-32 degrees. The air temperature right by the ground may be a little colder than this. During a light freeze, some of the water inside of a ...

Freeze (28–32°F): Water inside the plant freezes, expands, and ruptures cells and vascular tissue. This can cause lasting damage. Hard freeze (under 28°F): Higher chance of water freezing inside ...

We have the first video of a plant cell wall being built Plant cells without a cell wall are fragile, so it's hard to image its construction.

Frost can form even before air temperatures drop below freezing. And when the air temperature drops below freezing, plant cells freeze and die. Although frost will not cause as much damage as a hard ...
