Tendrils are grown and used by parasitic, invasive and/or climbing plants to spread and provide anchor points for further growth. In some species, tendrils will curl around anchor points and other plants, called hosts, but interestingly never curl around themselves. Pictured above is the end of a long 15 foot blackberry tendril pulled out of a tree in the grand forest.

“Frond” refers to a large divided leaf, especially ferns. Pictured above is a frond of a large Sword Fern found in the grand forest.
A Spore is usually a small single-celled reproductive unit capable of growing into an adult individual independently, similar to a seed. In this photo we see clumps of orange fern spores on the underside of a sword fern. For scale the blue footed booby is about 1.5 inches tall.

Seed dispersal is the means by which a parent plant spreads its child seeds about the environment. We can see here this dandelion plant has developed a way to disperse its seeds using the wind. The white tuft contains several seeds attached to a feather-like head, which pulls the seed up and away if the wind blows hard enough.
