A Phalaenopsis flower. Orchids are easily distinguished from other plants, as they share some very evident derived characteristics or synapomorphies.Among these are: bilateral symmetry of the flower (zygomorphism), many resupinate flowers, a nearly always highly modified petal (labellum), fused stamens and carpels, and extremely small seeds.
Orchid seeds are very small (0.35mm to 1.50mm long), spindle-shaped, and have an opening at the pointed end. [5] Each seed has an embryo that is undifferentiated and lacks root and shoot meristems. [3] An orchid seed does not have enough nutritional support to grow on its own, and lacks endosperm. [2]
Phalaenopsis (/ ˌ f æ l ɪ ˈ n ɒ p s ɪ s /), also known as moth orchids, [2] is a genus of about seventy species of plants in the family Orchidaceae.Orchids in this genus are monopodial epiphytes or lithophytes with long, coarse roots, short, leafy stems and long-lasting, flat flowers arranged in a flowering stem that often branches near the end.
Phaius orchids, also known as "nun's cap orchids," can grow up to 4 feet tall. They have large leaves at their base and flowers that come in colors like white, pink, red, and purple.
Phalaenopsis, or moth orchids, fall into this category, as do vanda orchids. Sympodial orchids grow from a rhizome or bulb and have multiple root systems. Cattleyas and oncidiums fall into this ...
Drymoanthus adversus often grows in moist forests near rivers or oceans, and chooses tree trunks and branches on ridges shrouded in thin mist or clouds as habitats. [7] The host of Drymoanthus adversus has strong diversity, and grows on various plant surfaces, including the vine Metrosideros fulgens, shrub Lophomyrtus obcordata, and tree fern Dicksonia squarosa.
Galearis rotundifolia is a succulent perennial herb growing from a fleshy rhizome. It reaches a maximum height around 33 centimeters. A single leaf clasps the base of the stem. It is variable in shape and size, reaching up to 11 centimeters in length. The inflorescence is a spike of flowers and leaflike bracts occupying the top of the stem. [3]
One of the outcomes of plant reproduction is the generation of seeds, spores, and fruits [13] that allow plants to move to new locations or new habitats. [14] Plants do not have nervous systems or any will for their actions. Even so, scientists are able to observe mechanisms that help their offspring thrive as they grow.
