Gymnosperms and Angiosperms: Grouping Gymnosperms

The video tutorial explores the four phyla of gymnosperms: Cycadophyta, Ginkgophyta, Gnetophyta, and Pinophyta. Cycadophyta includes cycads, which resemble palm trees and thrive in tropical climates. Ginkgophyta is represented by the maidenhair tree, known for its resilience and unique leaves. Gnetophyta consists of species like Ephedra, found in arid regions. Pinophyta, or conifers, are the largest and oldest living organisms, with examples like pines and redwoods. Conifers are vital for ecosystems and industries, providing wood and paper products.
