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.
Johnson grass or Johnsongrass, Sorghum halepense, is a plant in the grass family, Poaceae, native to Asia and northern Africa. [1] The plant has been introduced to all continents except Antarctica, and most larger islands and archipelagos. It reproduces by rhizomes and seeds.
Turtle grass can also sexually reproduce through the production of underwater flowers and hydrophily. Turtle grass is dioecious, which means that there are separate male and female plants, each which produce an imperfect flower containing only one sex. Sexual reproduction takes place from April to July depending on location, though flowering ...
Vegetative reproduction (also known as vegetative propagation, vegetative multiplication or cloning) is a form of asexual reproduction occurring in plants in which a new plant grows from a fragment or cutting of the parent plant or specialized reproductive structures, which are sometimes called vegetative propagules.
Sexual reproduction in Eriophorum angustifolium begins with flowering in spring or early summer (in or around May), when groups of 3–5 brown flowers are produced. [ 3 ] [ 11 ] Fertilisation usually takes place in May or June, via anemophily (wind-pollination), [ 20 ] and the white bristle-like perianth, composed of achenes with pappi (seeds ...
Ruppia maritima is an aquatic plant species commonly known as beaked tasselweed, beaked ditchgrass, [citation needed] ditch grass, tassel pondweed and widgeon grass. [2] Despite its scientific name , it is not a marine plant ; is perhaps best described as a salt-tolerant freshwater species. [ 3 ]
Aegilops triuncialis, or barbed goatgrass, is a grass species of the family Poaceae. [1] It is a winter annual native to many areas in Eastern and Mediterranean Europe and Western Asia . [ 2 ] It is considered an introduced , invasive species in North America, mainly in the Western coast of the United States. [ 3 ]
It is cultivated as an ornamental grass. This species also has potential as a noxious weed and is easily spread via seed contamination. It has been declared a weed in Puerto Rico and a potentially invasive weed in Mexico. [6] The seeds are eaten by songbirds and small mammals, while the larvae of certain butterflies feed on the plant. [7]
