Here's why:
* Trees are vascular plants, meaning they have specialized tissues for transporting water and nutrients. They are also classified as gymnosperms (like conifers) or angiosperms (flowering plants).
* Mosses are non-vascular plants, meaning they lack specialized tissues for transport. They are classified as bryophytes.
While trees and mosses have different structural and physiological features, they share several characteristics that place them within the plant kingdom:
* They are multicellular eukaryotes.
* They obtain energy through photosynthesis.
* They have cell walls made of cellulose.
* They reproduce sexually and asexually.
Therefore, both trees and mosses are classified as plants, despite their significant differences.
