Hydrilla ( waterthyme) is a genus of aquatic plant, usually treated as containing just one species, Hydrilla verticillata, though some botanists divide it into several species. It is native to the cool and warm waters of the Old World in Asia, Africa and Australia, with a sparse, scattered distribution; in Australia from Northern Territory ...
Conifers are a group of cone-bearing seed plants, a subset of gymnosperms. Scientifically, they make up the division Pinophyta ( / pɪˈnɒfɪtə, ˈpaɪnoʊfaɪtə / ), also known as Coniferophyta ( / ˌkɒnɪfəˈrɒfɪtə, - oʊfaɪtə /) or Coniferae. The division contains a single extant class, Pinopsida.
Arthropods ( / ˈɑːrθrəpɒd / ARTH-rə-pod) [ 20] are invertebrates in the phylum Arthropoda. They possess an exoskeleton with a cuticle made of chitin, often mineralised with calcium carbonate, a body with differentiated ( metameric) segments, and paired jointed appendages. In order to keep growing, they must go through stages of moulting ...
Evolutionary history of plants. A late Silurian sporangium, artificially colored. Green: A spore tetrad. Blue: A spore bearing a trilete mark – the Y -shaped scar. The spores are about 30–35 μm across. The evolution of plants has resulted in a wide range of complexity, from the earliest algal mats of unicellular archaeplastids evolved ...
The pineapple is an example of a CAM plant. Crassulacean acid metabolism, also known as CAM photosynthesis, is a carbon fixation pathway that evolved in some plants as an adaptation to arid conditions [1] that allows a plant to photosynthesize during the day, but only exchange gases at night. In a plant using full CAM, the stomata in the leaves ...
Hudson Volcano is a volcano in the rugged mountains of southern Chile. Lying in the Southern Volcanic Zone of the Andes, it was formed by the subduction of the oceanic Nazca Plate under the continental South American Plate. Hudson has the form of a 10-kilometre-wide (6-mile) volcanic caldera filled with ice.
Melastomataceae ( / mɛləstoʊmɑːˈteɪsiˌaɪ, - siːˌiː /) is a family of dicotyledonous flowering plants found mostly in the tropics (two-thirds of the genera are from the New World tropics) comprising c. 175 genera and c. 5115 known species. [ 3][ 4] Melastomes are annual or perennial herbs, shrubs, or small trees .
Labisia is a herbaceous plant that grows in low clusters, with solitary or rarely branching stems and fine, hairy roots. The leaves are oblong-shaped, hairy on its underside and can grow to 20–40 cm (7.9–15.7 in) in length. The inflorescence are brown and 5–6 cm (2.0–2.4 in) long. [ 4] The plant thrives under the shade, away from direct ...
