Plantae is a large and diverse kingdom which includes all of the trees, grasses, ferns and mosses in the world. All plants are eukaryotes, with nucleated cells and organelles such as mitochondria and chloroplasts. Their cells have distinct cellulose walls that other organisms lack. All plants are descended from a common ancestor.Continue Reading
The world's 250,000 species of plants range over almost every biome on Earth and represent a huge fraction of life's total biomass. Plants have adapted to arid deserts, frozen mountainsides and the open ocean. Despite their diversity, however, all plants share some traits in common.
All plants are able to capture sunlight for use in synthesizing complex organic molecules. This process, known as photosynthesis, works on the cellular level and involves a symbiotic relationship with what was once a free-swimming variety of cyanobacteria called chloroplasts. Chloroplasts dwell inside the cells of plants and carry out the chemical heavy lifting of capturing sunlight with chlorophyll.
One byproduct of photosynthesis is free oxygen. All plants release oxygen as a waste gas after stripping electrons from water during the sunlight conversion process. Plants concentrate their chloroplasts in their leaves, which are perforated with microscopic holes called stoma that take up carbon dioxide and release oxygen.Learn more about Botany
Organisms in the kingdom Plantae, commonly referred to as plants, are multicellular, have specialized reproductive organs, unique cell structures and produce food using photosynthesis. This kingdom includes all land plants and some aquatic organisms as well. Plants are remarkably different from animals in appearance, but have important biological distinctions as well, especially at the cellular level.Full Answer >
Spore-producing plants include ferns, mushrooms, liverworts, hornworts and mosses. Other plants that produce spores are rusts, smuts, earthstars, stinkhorns and horsetails. Spores are reproductive bodies that can be sexual or asexual.Full Answer >
Four examples of plant life are mosses, ferns, conifers and flowering plants. The main differences are in how they reproduce. The oldest forms of plants require water to germinate, while the newer ones can reproduce on dry land.Full Answer >
According to the Botanical Society of America, botany is the scientific study of plants, which includes algae, fungi, lichens, mosses, ferns and flowering plants. The people who work in botany, or botanists, can choose from a wide variety of careers.Full Answer >
