Bananas! They've got a long trip from harvest to table, and a lot of science goes into keeping them delicious

There is a chemical reaction discovered a century ago that could be the key to creating everything from fuel to shelter on Mars!

Paul Andersen explains how plants use hormones to respond to their environment. The following hormones are detailed; auxin, cytokinins, gibberelins, abscisic acid and ethylene.

Abscissic acid induces seed dormancy which is relieved by Gibberilin. Then, Auxin and cytokinin promotes growth of the plant, and finally ethylene induces flowering and senescence. Two hormones important for seed dormancy are Gibberin...

When we discussed basic information regarding homogeneous and heterogeneous catalysis, we mentioned hydrogenation of alkenes in both of these contexts. Now let's get more specific and describe the mechanism of this precise catalysis in...

Unripe bananas travel from all around the world but always end up ripe and yellow on the supermarket shelves. This experiment shows us how. Chemistry - Chemical Industries - Learning Points. Millions of bananas are exported across the...

The study found that some of the commonly-used plastics release methane and ethylene one they are exposed to sunlight.

Ethylene Function and Synthesis in Plants

it explains the chemical nature, discovery, physiological effects of Auxins, Gibberellins, Cytokinins, Abscisic Acid and Ethylene and their Applications.

In this video we are going to look at a few different ways in which plant hormones can be used.



Plant growth hormones (auxins) can be used as selective weedkillers. The selective weedkillers contain growth hormones,...
