Question: Answer the following question given this paragraph: Conifers Conifers are the dominant phylum of gymnosperms, with the most variety of species. Most are tall trees that usually bear scale-like or needle-like leaves. The thin shape of the needles and their waxy cuticle limits water loss through transpiration. Snow slides easily off needle-shaped leaves, keeping the load light and decreasing breaking of branches. These adaptations to cold and dry weather explain the predominance of conifers at high altitudes and in cold climates. Conifers include familiar evergreen trees, such as pines, spruces, firs, cedars, sequoias, and yews (Figure 14.20). A few species are deciduous and lose their leaves all at once in fall. The European larch and the tamarack are examples of deciduous conifers. Many coniferous trees are harvested for paper pulp and timber. The wood of conifers is more primitive than the wood of angiosperms; it contains tracheids, but no vessel elements, and is referred to as "soft wood. Q: Conifers are the dominant phylum of gymnosperms, with the most variety of species. most are tall trees that usually bear scale-like or needle-like leaves. the thin shape of the needles and their waxy cuticle limits water loss through this? Choices: - evaporation - transportation - sedimentation - transpiration A:
Answer:
transpiration
