Final answer:
Conifers are evergreen, cone-bearing trees in the boreal forest, such as pines, firs, spruces, cedars, and redwoods. They retain their needle-shaped leaves year-round and have adaptations to survive cold and dry weather. Conifers are the dominant phylum of gymnosperms.
Step-by-step explanation:
Conifers are evergreen, cone-bearing plants that dominate the boreal forest. They include trees such as pines, firs, spruces, cedars, and redwoods. These trees retain their needle-shaped leaves year-round, allowing them to photosynthesize earlier in the spring than deciduous trees. Conifers have adaptations to cold and dry weather and are the tallest living vascular plants.
