Description
A deciduous tree is a tree that sheds its leaves annually, typically in response to changes in seasonal temperature and light patterns. These trees are characterized by their leaves turning colour and falling off in the fall, followed by a dormant period without leaves in the winter and new growth in the spring. Deciduous trees are common in temperate and subtropical regions and play an important role in the ecosystem by providing habitat, food, and oxygen. Plants belong to the kingdom Plantae and are mostly multicellular, photosynthetic eukaryotes. The flowering plants, conifers and other gymnosperms, ferns and their associates, hornworts, liverworts, mosses, and the green algae all belong to the clade Viridiplantae (Latin for “green plants”), which excludes the red and brown algae. In the past, all algae and fungi were considered part of the kingdom of plants, one of the two kingdoms that included all living creatures other than animals. However, all current classifications of Plantae exclude prokaryotes, certain algae, and fungi (the archaea and bacteria). Green plants need primary chloroplasts, produced due to an endosymbiotic relationship with cyanobacteria, to photosynthesise most of the energy they receive from the sun. They are green because their chloroplasts contain chlorophylls a and b. Some plants lose their capacity to produce normal chlorophyll levels or photosynthesize because they are parasitic or mycotrophic. Although asexual reproduction is also frequent, sexual reproduction and generational alternation are what define plants.
Coniferous trees, also known as evergreen trees, are a type of tree that are characterized by their needle-like or scale-like leaves and cone-like fruit. Unlike deciduous trees, which lose their leaves each year, coniferous trees retain their leaves year-round, making them an important source of year-round greenery.
Coniferous trees are found throughout the world, in a range of environments, from cool, moist temperate forests to dry, arid regions. They are well-adapted to harsh climates and can grow in areas with limited water availability.
These trees are commercially important, with many species used in the production of timber and paper, as well as in landscaping, reforestation, and ornamental horticulture. Some well-known examples of coniferous trees include pine, spruce, fir, cedar, and juniper.
The growth habit of coniferous trees can vary widely, from low-growing shrubs to towering trees that can reach heights of over 300 feet. They are known for their long lifespan, with some species living for thousands of years.
