The document discusses the differences between coniferous and deciduous trees. Coniferous trees have needle-shaped leaves, cones that hold their seeds, and are evergreen, keeping their leaves year-round. Deciduous trees have broad, flat leaves, lose their leaves annually in fall, and bear seeds in flowers. Examples of coniferous trees include pine, spruce, and fir, while deciduous trees include oak, maple, beech, aspen, and ash. The document also examines external leaf structure, parts of a flower, and flower arrangements.
