A young root –the first organ to emerge during seed germination---WHY?

Adventitious roots

Root tip Slimy layer root hairs rootcap Root apical meristem

epidermis cortex Cross section of primary root endodermis Vascular cylinder stele

pericycle Primary xylem Primary phloem xylem Cross section of primary root

Dicot root cross section Stele: A = xylem B = phloem C = endodermis Dicot root cross section

storage

Pneumatophores -- for gas exchange in waterlogged soil

Contractile roots --thickened specialized roots at the base of a corm, bulb, or other organ which is designed to shrink vertically under conditions of seasonal drought  that helps position this plant part at an appropriate level in the ground.

Haustoria – suckers of parasitic plants for obtaining nutrients from their hosts

Mycorrhizae –mutualistic relationship between plant roots and fungi Pinus strobus with Amanita muscaria

Root nodules --–mutualistic relationship between plant roots and N-fixing bacteria
