Coniferous trees have needles in place of leaves, while deciduous trees have broad leaves.
Coniferous trees retain the color of their needles when it’s Fall, while the leaves of deciduous trees change color during the Fall.
Coniferous trees have no flowers, so they use cones to propagate their seeds. Deciduous trees produce flowers, which they use to propagate their seeds.
The absence of broad leaves in conifers helps them conserve energy.
Deciduous trees lose their leaves before Winter, to conserve energy.
Conifers generally produce cones instead of flowers. E.g, pine cones.
Examples of deciduous trees are oaks, almonds, and elm.
