The Secret

Cordgrass ordgrass grows in marshy areas along shorelines. It looks tall, tough, and swordlike. During high tides this plant is mostly submerged in sea water. At low tide the water drains off the marsh, leaving the cordgrass mainly exposed.

Strangely, cordgrass needs fresh water to live, yet it grows in salt water. How can this be?

Well, a special membrane in its root pulls fresh water out of sea water. This membrane filters out most of the salt before it can enter the plant’s sap. Then special glands along the surface of the plant pluck out any salt that got past the membrane. These glands pass the salt through pores that deposit the salt on the outside of the grass blades. At the next high tide, the salt gets washed off the plant. If any of these systems fail to work, the salt will kill the grass.

The theory of evolution teaches that life started from a blob and just kept changing until it worked. But if cordgrass took millions of years to evolve, how did it keep from dying off before it gained the ability to process salt water?

The Bible says, “In the beginning God created the heavens and the earth.” Things didn’t just fall together. A very loving God made them.

TRY IT: Get three plants. For three weeks water one with fresh water and two with salt water. What happens with each plant? How does the soil look?
