Trees play a significant role in reducing erosion and moderating the climate.
Palms, bananas, and bamboos also produce seeds, but tree ferns produce spores instead.
Trees and forests provide a habitat for many species of animals and plants. Tropical rainforests are among the most biodiverse habitats in the world.
Trees usually reproduce using seeds. Flowers and fruit may be present, but some trees, such as conifers, instead have pollen cones and seed cones.
They remove carbon dioxide from the atmosphere and store large quantities of carbon in their tissues.
