Most trees reach for the sun – but not the weeping willow. Why?

Daffodils are cheerful symbols of spring… and also cold blooded killers. But it turns out, the poison in these plants may actually be helpful to us humans!

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

Plants don’t have brains or muscles, and yet some of them can perform such feats as eating insects or following the sun. Scientists haven’t completely figured out how this happens, but they do have some pretty strong leads.

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...

A type of plant hormone that affects growth and development, often encouraging root or stem growth.

Plant Physiology and Chemistry Set: 7. This clip explains how light causes the release of the hormone auxin, which affects the growth and movement of plants.

The video explains how plant hormones, specifically auxin, affect the growth and direction of plant shoots and roots in response to light and gravity. It discusses the different effects of auxin on plant cells in shoots and roots and how...

The video discusses how plants grow and respond to changes in their environment through the use of plant hormones, specifically auxin. The presenter talks about the concept of tropism and how auxin controls the growth of both shoots and...

Gravitrophism In Plants: This clip explains how plants respond to the force of gravity through gravitrophism.

If a plant has enough water, minerals and energy it will grow right? Well sort of… but there is more to it - like why do plants bend towards the light and not just grow straight? And how come the stem grows up but the roots grow down? It...
