radicle

Two days later, plasma-treated seeds showed larger radicles, or starter roots.

And, lastly, that at the apex of the nucleus the radicle of the future Embryo would constantly be found.

An uncharged SO4 radicle would react with the water present, and sulphuric acid would be formed and oxygen liberated.

Also imagine one atom of oxygen with its two hooks outstretched like two arms, and just link one radicle on to each.

If we use the methyl radicle we get methyl alcohol: if we use the ethyl radicle we get ethyl alcohol.

The form and relative position of the radicle and cotyledons serve to distinguish certain groups of plants.
