Self-pollination refers to the process in which pollen lands on the stigma of its own flower or another flower on the same plant. Pollination in plants is the process where pollen is transferred from the anther, the male part of a flower, to the stigma, the female part of a flower. Examples: Zostera Ceratophyllum Najas Epihydrophily Plants which are pollinated outside the water. Cross-pollination is mainly seen in dark and bright colored flowering plants, where insects like butterflies and honey bees are attracted by their bright colored flowers. There charitaceae-epihydrophily), underwent a parallel evolu- are four types of pollination mechanisms in Hydrochar- tion. 14. Male flowers after breakage floats on the surface of water.

Hydrophily is a fairly uncommon form of pollination whereby pollen is distributed by the flow of waters, particularly in rivers and streams. This happens in plants that have flowers called angiosperms. Epihydrophily : Plants which are pollinated outside the water. There are some bisexual flowers that never open. There are two types of hydrophily: Epihydrophily and Hypohydrophily. It is a type of hydrophily which occurs on the surface of water. In Epihydrophily pollination take place on the surface of water. This is resembling the pollen which is needed for pollination to happen. flowers and have the same manner of pollination as their terrestrial ancestors (Arber, 1920; Scul-thorpe, 1967). Pollination by water is quite rare in flowering plants and is limited to about 30 genera, mostly monocotyledons. Examples: Vallisneria spiralis, Elodea. Callistemon (Bottle brush) is pollinated by birds and is an example of ornithophily. The milkweed or butterfly weed already mentioned is another example of a flower adapted to insect pollination. 3. In Val/isneria pollination occurs outside water called epihydrophily. is the male part of a flower and transferred to the flower’s female part called the stigma Epihydrophily is a pseudo hydrophily that … Clipping is a handy way to collect important slides you want to go back to later. Pollination in Vallisneria spiralis: It is a dioecious, submerged and rooted hydrophyte. Apples, tulips, lavender, strawberries, beans, dandelions are some examples of plants with cross-pollination. Salvia is insect pollinated and is an example … Epihydrophily : Pollination occurs on the surface of water. Eg: Zostera (sea horse) 2. (ii) Hypohydrophily: When the pollination takes place inside the water, it is called hypohydrophily. A flower is fragrant (or stinky) so it could attract pollinators.

SELF POLLINATION It is the transfer of pollen grains from the anther of a flower to the stigma of either the same or genetically similar flower. Examples from Classical Literature As the result of the pollination the ovary developes into a dry 1-seeded indehiscent fruit. Hydrophilous species fall into two categories: (i) Those that distribute their pollen to the surface of water. At maturity … POLLINATION Two types of pollination Self-pollination Cross-pollination 4. In case of fully submerged plants, the flowers are either pollinated via the water current, called hypohydrophily. Pollination in Vallisneria spiralis: It is a dioecious, submerged and rooted hydrophyte. Examples : Mirabilis, Gardenia, etc. Example: Zostera. In Zostera, the marine angiosperm (Sea Grass), the pollen grains are long ribon-like (upto 2500 mm) and without exine. ADVERTISEMENTS: In this article, we will discuss about the three agents for pollination. Some examples of water pollinated plants are Vallisneria and Hydrilla which grow in fresh water and several marine sea-grasses such as Zostera.

When the male flowers are mature, the individual anthers break off and settle through the water until they reach a groove near the stigma of a female flower, leading to pollination. Epihydrophily: Pollination occurs on the surface of water. Adaptations for Water Pollination: Water pollination is also termed as hydrophily and mode of pollination is water. Far fewer exhibit a system whereby water is the vector for pollen transfer, i.e., hydroph-ily. About 80% pollination occurs by insects like moths, beetles, butterflies, wasp, etc. Many animals are involved in pollen transfer Zoophily : Here the pollen grains are transferred from one plant to another by the help of vertebrate animals, bats, birds etc.This occurs due to dependence of animals on plants for food. e.g.Vallisneria (Ribbon weed). It is of two types. By pollination we mean the transfer of pollen from an anther to the stigma of a flower. """GFZˆXˋš6*(ì%cÈø#¨¸',m,p",|Ɋ¶.Ò I have them look at their napkin (pollen) again and I explain, "The substance that stuck to your fingers earlier, is key to the reproduction process. Example: Vallisneria. Most plants use cross-pollination. (ii) Biotic agents (a) Entomophily : When pollination is brought about by the agency of insects, it is known as entomophily or insect pollination. Epihydrophily :Plants which are pollinated outside the water. Hydrophily: Pollination by water is known as hydrophily.

(i) Epihydrophily: When the pollination takes place on the surface of water, it is called epihydrophily. Hypohydrophily occurs below the surface of water, e.g., Zostera, Ceratophyllum. Vallisneria's male flower or pollen grain are released on the surface of water, which are passively carried away by water currents; some of them eventually reach the female flower (ii) Those that distribute it beneath the surface. • Pollination takes place through water. a. Epihydrophily: Pollination occurs at the water level. Pollination: Pollination is the transfer of pollen from the stamens to the stigma of flowers. Pollen can be transferred to one plant or even a nearby plant so that they can get fertilized and make more flowers. Common examples of wind pollinated flowers are grass, sugarcane, bamboo and coconut, etc. The Pollination Process. seagrasses in which female flower re… Two general, but sometimes rather arbitrary, forms of hy drophily are recognized: 1) epihydrophily; pollination via pollen transport at the water surface (two-dimensional), and 2) hypohy drophily; pollination via pollen … ôˆS%ï á÷ü´÷ÌÔivÙâ] kh6\4\:\@|¾g‚3¬Ô•251¹`õŸ5#E„•BD„5½¢€‚hŠ€å“‚¶É€…>d!RADA`*Š ã-Ðà,ph|V=tìí­SEɁà«Á*5ÕºªJ%×Z“hs+*¹Ö8 In Hypohydrophily pollination take place inside the water. e.g. Pollen grains are long, without exine, heavier than water , sink down to meet stigma of female flowers. Hydrophily (Water Pollination): (Gk, Hydro = water and Philein = to love) Hydrophily takes place only in few aquatic plants. Examples: Vallisneria spiralis, Elodea. Flowers are small, colourless, inconspicuous, nectar less and become arranged as inflorescence. Imagine a flower that can produce heat to lure in pollinators and keep them happy. It has already been stated that pollination, in a vast majority of cases, involves some agent. ∾ÀZ ,Q®¢+¡ìq‘ÃÙ`€²gRþÊa€Ž½@DQèìP -ç]¢³—֏„´åRzbvzž.š”Hx†ç&”:æ%ÆM…֝aab1‚° ±ô@ðGXX#X)DD»k ø¬2aʲE Pollination by animals is called Zoophily. Hypohydrophily - pollination occurs below the surface of water. Pollen can be carried by insects, other animals, wind, or water. It is a very rare type of pollination, even in aquatic plants. Examples: Vallisneria and Ruppia. Pollination is a process in which pollen is transferred to the female reproductive organs of seed plants, thereby enabling fertilizationand reproduction through growth of the pollen tube and eventual release of sperm. Get ready for the next lesson. water is a regular mode of transport for the male gametes among the lower plant groups such as algae, bryophytes, and pteridophytes. Hypohydrophily is a true hydrophily that occurs beneath the surface of water. The usual agents are wind, animals and water.

The aquatic plants depend on water for the transfer of pollen grains. Hydrophylly is of two types— hypohydrophily and epihydrophily. a. Epihydrophily: Pollination occurs at the water level. Hypohydrophily : Pollination occurs below surface of water. Examples of anemophilous plants are coconut palm, date palm, Cannabis and many grasses. Examples: Ceratophyllum, Najas Zostera and Hydrilla Specific gravity is found in pollen grains so they remains suspended in water. Reproduction: Questions 53-60 of 119. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Specific gravity of pollen grains is equal to that of water, so they float on water. Pollination: When pollen is transferred from the anther to the stigma. The female flower have a very long pedicel, therefore it reaches the surface of water.

Biotic agents (a) Entomophily : When pollination is brought about by the agency of insects, it is known as entomophily or insect pollination.
