Question

What is Sequoia Sempervirens?

Answer 1

The term "Gymnosperm" is derived from the Greek words "gymnos" (naked) and "Sperma" (seed), thus "Naked seeds". Plants that produce seeds are known as gymnosperms, and unlike angiosperms, they do not produce fruits. These plants form a cone-like structure on the surface of scales or leaves, or at the end of stalks.

Complete answer:
Trees are much larger than terrestrial animals, and they can reach enormous sizes. A typical adult human stands around 1.8 meters tall; the Atlantis (a space shuttle) stands 56 meters tall, and General Sherman (Sequoiadendron giganteum) stands 83.8 meters tall. The Hyperion (Sequoia sempervirens) is the world's tallest gymnosperm (and tree) at 115.85 meters.
The Hyperion is a type of coastal redwood that can be found in the Redwood National and State Parks in northern California. The tree is estimated to be around 600 years old (by Stephen Sillett), but some people believe it is over 700 years old. To ensure that the tree is not harmed, the exact location of the tree is kept a secret.
The only living species of the genus Sequoia in the cypress family Cupressaceae is Sequoia sempervirens. They're also known as redwoods, coastal redwoods, and so on. It's the tallest, most evergreen, and longest-lived gymnosperm on the planet.
These trees are also some of the world's oldest living things. This massive tree grew naturally in an estimated 810,000 hectares (2,000,000 acres) along much of coastal California (excluding southern California, where rainfall is insufficient) and the southwestern corner of coastal Oregon in the United States before commercial logging and clearing began in the 1850s.
Gymnosperm leaves are well adapted to extremes of climate. A plant with a trunk measuring 9 meters in diameter has grown to a height of 377 feet.
Thus, Sequoia sempervirens is the only living member of the genus Sequoia, which belongs to the Cupressaceae family of cypresses. Coast redwood, coastal redwood, and California redwood are all common names for this species. It is a monoecious, evergreen tree with a lifespan of 1,200–2,200 years.

Note:
Zamia pygmaea is the world's smallest living cycad and (presumably) gymnosperm, growing no more than 10 inches tall. This plant is only found in Cuba and is known by a variety of names, including "guayaro," "guayra," and "guayra".
