  • Damn Nature, you scary!

  • The stem looks so creepy

  • The day of the Lord. Jesus is going to reign on earth.

  • the roots look creepy

  • No, French beans have epigeal germination - the hypocotyl extends below the cotyledons and lifts them above the surface of the soil at germination. On any dicotyledonous plant, if the the seed leaves appear above ground first it is epigeal germination, and if the true leaves appear straight away it is hypogeal germination (hypo means below, epi means above).

  • @APurseyful- do all beans display hypogeal germination?

  • This is great, and shows how the epicotyl extends to lift the plumule out of the ground, leaving the cotyledons in the testa. Lovely detail of root hairs and lateral roots too.
