Aerial roots are roots that are aboveground. A banyan is a fig that starts its life as an Epiphyte when its Seeds germinate in the cracks and crevices on a host Tree (or on structures like Fort Myers is the County seat and commercial center of Lee County, Florida, United States. ROOT is an object-oriented program and library developed by CERN. They are almost always adventitious. They are found in diverse plant species, including epiphytes also known as air plants, which includes the orchids, tropical coastal swamp trees such as mangroves, the resourceful banyan tree, the warm-temperate rainforest rātā and pōhutukawa trees of New Zealand and vines like English ivy and irritating poison ivy.

Types of aerial roots

This plant organ that is found in so many diverse plant families has different specializations that suit the plant habitat. In general growth form, they can be technically classed as negatively gravitropic (grows up and away from the ground) or positively gravitropic (grows down toward the ground). Gravitropism ''geotropism'' is a turning or growth movement by a Plant or Fungus in response to Gravity.

Aerial roots as supports

Non-parasitic ivy are vines that use their aerial roots to cling to host plants, rocks, or houses. Hedera (English name ivy, plural ivies) is a genus of 15 species of climbing or ground-creeping Evergreen woody plants in the family Prop roots form on aerial stems and grow down into the soil to brace the plant, e. g. maize and screw pine. Maize (ˈmeɪz ( Zea mays L. ssp mays) known as corn in some countries is a cereal grain domesticated in Mesoamerica Pandanus is a Genus of Monocots with about 600 known Species.

Stranglers

The Banyan tree (Ficus sp. A banyan is a fig that starts its life as an Epiphyte when its Seeds germinate in the cracks and crevices on a host Tree (or on structures like Ficus is a Genus of about 850 Species of woody Trees Shrubs Vines Epiphytes and hemi-epiphytes in the family ) is an example of a strangler fig that begins life as an epiphyte in the crown of another tree. An epiphyte is an organism that grows upon or attaches to a living plant Its roots grow down and around the stem of the host, their growth accelerating once the ground has been reached. Over time, the roots coalesce to form a pseudotrunk, eventually strangling and killing the host. Another strangler that begins life as an epiphyte is the Moreton Bay Fig {Ficus macrophylla) of tropical and subtropical eastern Australia, which has powerfully descending aerial roots. Ficus macrophylla, commonly known as the Moreton Bay Fig, is a large evergreen Banyan tree of the Moraceae family that is a native of most In the subtropical to warm-temperate rainforests of northern New Zealand, Metrosideros robusta, the rātā tree, sends down aerial roots down several sides of the trunk of the host. Northern rātā ( Metrosideros robusta) is a huge forest tree endemic to New Zealand. From these descending roots, horizontal roots grow out to girdle the trunk and fuse with the descending roots. Eventually the host tree dies, leaving as its only trace a hollow core in the massive pseudotrunk of the rātā.

Pneumatophores

These specialized aerial roots enable plants to breathe air in habitats that have waterlogged soil. Soil, often typeset as SOiL, is a four piece rock band from Chicago Illinois United States founded by Shaun Glass Tom Schofield Tim King and Adam Zadel The roots may grow down from the stem, or up from typical roots. Some botanists classify these as aerating roots rather than aerial roots, if they come up from soil. The surface of these roots are covered with lenticels which take up air into spongy tissue which in turn uses osmotic pathways to spread oxygen throughout the plant as needed. A lenticel is a spongy area present in the cork surfaces of the stems roots and other parts of vascular plants Osmosis is the Diffusion of a solvent (frequently water through a semi-permeable membrane, from a solution of low solute concentration (high water potential

Black mangrove is differentiated from other mangrove species by its pneumatophores. Avicennia germinans, the black mangrove, plays a key role in the Mangrove ecosystem by trapping debris and detritus brought in by tides and as feeding

Haustorial roots

These roots are found in parasitic plants, where aerial roots become cemented to the host plant via a sticky attachment disc before intruding into the tissues of the host. In the biology of trees a cypress knee is a distinctive structure in a root of a cypress Tree of any of various species of the subfamily Taxodioideae. A parasitic plant is one that derives some or all of its sustenance from another plant Mistletoe is a good example of this. Mistletoe is the common name for a group of hemi-parasitic Plants in the order Santalales that grow attached to and within the

Propagative roots

Horizontal, aboveground stems, termed stolons or runners, usually develop plantlets with adventitious roots at their nodes, e. g. strawberry and spider plant. Garden strawberries are a common variety of strawberry cultivated worldwide Chlorophytum is a genus of about 200-220 species of Evergreen perennial Flowering plants in the Agavaceae, native to the tropical

Some leaves develop adventitious buds, which then form adventitious roots, e. g. piggyback plant (Tolmiea menziesii) and mother-of-thousands (Kalanchoe daigremontiana). Kalanchoe daigremontiana syn Bryophyllum daigremontianum also called Devil's Backbone, Alligator Plant, Mexican Hat Plant The adventitious plantlets then drop off the parent plant and develop as separate clones of the parent. Cloning in Biology is the process of producing populations of genetically-identical individuals that occurs in nature when organisms such as Bacteria, Insects
