Day 15: How Plants Along the River Survive Flooding

When we experience increased precipitation, mammals will normally respond by seeking shelter from the storm. But what about the life of the immobile – what do they do? Plants have longed evolved adaptations to surmount gas┬ádeprivation by specialized root systems known as adventitious roots. These roots are produced from ┬áthe shoot cells, grow aerially to capture carbon dioxide and release oxygen above the water surface, and allow for propagation. Examples of plants with this adaptation include: black willow, american sycamore, and river birch.

A secondary method by which gas exchange occurs during a submergence or flood is known as having “cypress knees”. Cypress trees are famous for having laterally-extending woody projections from the top of the soil to access the air. These knees are also known for the structural role they play.
