Hypogeal germination of broad bean and root growth

Here is a time lapse of a Broad bean showing hypogeal germination and root growth.

‘Hypogeal’ means ‘underground’.
This is when the cotyledons of the germinating seed / bean remain below ground.
salts in the soil.

Roots and root hairs
The main functions of root are:
Absorption of water and nutrients,
Fixation of the plant to the soil,
Root bears unicellular root hairs.

Conduction of water and nutrients to aerial parts of plants

Root cap.

It is a cap-like structure at the tip of root. It cover and protects the growing point from injury as it pushes through the soil.

More of my time-lapse sequences can be found on Youtube

I have made an on-line interactive plant finder, identifier and pruning guide web site.  www.rightplants4me.co.uk which I hope you find interesting.

It has over 3,600 garden plants, 10,000 photographs plus time lapse sequences and each plant has in-depth plant care and illustrated pruning advice.

The plant database is continuing to grow.  If you have good quality photographs of garden plants that are not not already on the database I’d like to hear from you with an interest of adding it to the collection.
