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.
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.
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 ...
Papyrus plant (Cyperus papyrus) at Kew Gardens, LondonThis tall, robust aquatic plant can grow 4 to 5 metres (13 to 16 ft) high, [5] but on the margins of high altitude lakes such as Lake Naivasha in Kenya and Lake Tana in Ethiopia, at altitudes around 1,800 m (6,000 ft) the papyrus culms can measure up to 9 m (29 + 1 ⁄ 2 ft) in length, with an additional 46 centimetres (18 in) for the ...
When the smut invades the host plant it causes hypertrophy – the host's cells increase in size and number. (The fungus also destroys the flowering structures of the plant, so it does not make seed, but the plants can still be propagated asexually by rhizome.) In an environment such as a rice paddy, new sprouts of wild rice are easily infected ...
Syringodium filiforme, commonly known as manatee grass, is a species of marine seagrass. It forms meadows in shallow sandy or muddy locations in the Caribbean Sea and the Gulf of Mexico, and is also found in the Bahamas and Bermuda. [1] [2] It occurs to a depth of about 20 m (66 ft), and even deeper where water is very clear. [1]
This grass usually grows in coastal habitat, especially on dunes. It can be an important part of dune ecology. The grass usually grows on the foredune and on embryo dunes, less often on the backdune. [6] [7] [8] It is one of the first plants to establish in the process of ecological succession in the early stages of the development of a sand ...
