What Is A Samara And What Do Samaras Do
Flowering plants produce fruits after blooming, and the purpose of the fruits is to disperse seeds to grow new plants. Sometimes the fruits are tasty and eaten by animals, and this helps disperse seeds to new areas. Other plants use the power of wind to disperse the seeds in their fruits, and these include the samara producing trees. What is a Samara? A samara is just one type of many fruits produced by flowering plants. The samara is a dry fruit, as opposed to a fleshy fruit, like an apple or cherry. It is further categorized as a dry indehiscent fruit. This means that it does not split open to release the seed. Instead, the seed germinates inside of its casing and then breaks free of it as the plant grows. A samara is a dry indehiscent fruit with a casing or wall that extends to one side in a wing-like shape – in some plants the wing extends to both sides of the seed. Some samara fruits split into two wings, technically two samaras, while others simply form one samara per fruit. The wing causes the fruit to move through the air while spinning, like a helicopter. As a kid you probably threw samaras from maple trees up in the air to watch them spin back down to the ground. You may have called them helicopters or whirlybirds.
What Do Samaras Do?
The purpose of samara fruits, as with all fruits, is to disperse seeds. The plant reproduces by making seeds, but those seeds need to find their way into the ground so they can grow. Seed dispersal is a big part of flowering plant reproduction. Samaras do this by spinning to the ground, sometimes catching the wind and traveling farther. This is ideal for the plant because it helps it spread and cover more territory with new plants.
