The flower of this plant is compared to
Orchids and Snapdragons for beauty, but lurking under these beautiful
flowers and stems in fresh water areas of the world is “one of the
most sophisticated structures in the world.” The plant is commonly called a bladder-wort, its formal name is Utricularia, and it lives
its life in the water.
The underwater structure is a trap, a
hollow bladder. It is used by the plant to capture and digest living
creatures. This plant bladder eats any living thing in the water
including tadpoles, insects, and small fish fry. So how does it work?
The bladder is a precision instrument
that uses pressure to bring prey into the bladder. When the bladder
is full of water it pumps the water out through special cells
designed to let water out but not let it back inside. As it pumps the
water out the outer lining of the bladder is drawn in to create the
resistance necessary to draw water, and unsuspecting prey, in through
a trap door hinged by a special elastic material.
Extending from the door bottom are hairs that work like doorknobs.
When they are touched the door opens and the bladder expands to suck
in water and whatever creature touched the hairs.
Here is another complex system which
provides more evidence of design and therefore a designer.
You would just pass these by thinking that they are harmless. It's interesting that they have these complex mechanisms designed to help them catch food.
ReplyDeleteI didn't realize that they were carnivorous plants. The only one that usually comes to mind is the Venus fly trap. However that has its mechanism in plain sight.
This one is quietly gobbling up insects underwater. Thanks.
