Flowers of animal-pollinated plants usually have larger showy petals of different shapes and sizes to attract pollinators. Flowers of wind-pollinated plants typically have very small or no petals, making it easier for airborne pollen to come in contact with the stigma. In wind pollinated flowers, the inflorescence is generally pendant for the purpose of swinging. Wind pollinated flowers rely on wind to carry the pollen from the anther of a flower to the stigma of another flower. ADVERTISEMENTS: In this article we will discuss about:- 1. 1. Advantages and Disadvantages of Cross-Pollination 3. Asteraceae - Asteraceae - Pollination: The members of Asteraceae, together with the other families in the order Asterales, employ a system of pollination known as plunger, or secondary, pollination. Wind pollinated flowers possess the following characteristics : They are small and dull-coloured, often without petals. Wind pollinated flowers are scentless,have no nectar,have feathery stigma and are small with dull colors. … The anther is well exposed. Wind pollinated flowers Animal pollinated flowers 1. Large and coloured petals to attract insects. Dull colored small petals without fragrance 2. Wind and water pollinated Wind-pollinated plants do not need colorful flowers as they are not pollinated by animals, insects or birds. The diagram below represents an insect-pollinated flower cut to show the inner parts. Meaning of Cross-Pollination: If pollen grains are carried to the stigma of a flower of the same species growing on a different plant, it is cross-pollination. The pollen grains are light and non-sticky so that they can The perianth lobes are reduced. Some species of flowers release pollen that can float on water; pollination occurs when the pollen reaches another plant of the same species. Two i mportant physical characteristics of wind pollinated flowers: Male part of the flowers (anther and filament - which together are called the 'stamen') are designed to expose pollen to the wind so that pollen can easily be blown by air currents. Wind pollinated vegetation have boring color and have a lot much less showy petals (inconspicuous flowers) on account of they do not need to draw bugs. Cleistogamous flowers are by necessity found on self-compatible or self-fertile plants. In most of them the petals are highly aborted or absent. Wind pollinated (anemophilous) flowers have the following characteristics : (i) Flowers are small, colourless, odourless, nectarless and inconspicuous. Wind-pollinated plants don’t normally have flowers, but when they do they are small, don’t have perfumes or nectar, produce large amounts of light pollen, have stamens and stigmas exposed to air currents to either catch or distribute pollen and don’t normally have flower petals. The main adaptations of wind pollinated plants are: The flowers are small inconspicuous, lacks fragrance and nectar. 3. are not attractive and scent emitting. (ii) Calyx and corolla or perianth are reduced and are not attractive and scent emitting. Wind-pollinated flowers have the following characteristics: Most of them do not have petals. The Features of Water Pollinated Flowers: Water pollinated plants are Vallisneria, Hydrilla and Zostera (Marine grass). Some cleistogamous flowers never open, in contrast to chasmogamous flowers that open and are then pollinated. The genus Rubus (blackberries, raspberries, and brambles) chiefly contains arching shrubs or scramblers of irregular, often tangled appearance. When these characteristics are experimentally modified (altering colour, size, orientation), pollinator visitation may decline. Stigma may be large and are feathery and projected beyond the floral envelopes so that they can easily catch the pollen carried by the wind. Many economically important trees are also wind-pollinated, such as pines, spruces, firs and many hardwood trees. Wind is another good agent of pollination. Wind pollinated flowers 1.Large production of pollen grains. b. Pollen grains are small, light, dry, dusty and sometimes winged so that they are blown away to long distances. 4.Feathery and sticky stigma. Flowers evolved as a way for plants to entice insects, birds and mammals to help them spread their pollen around. The part of the flower which attracts insects is A. J B. K C. L D. M 16. Nectar to attract insects. Ans.Floral characteristics of a wind pollinated plant are: (i) Well exposed stamens for the pollen grains to be carried away easily. Characteristics of Hummingbird-Pollinated Flowers. No nectar 3. … Flowers are very conspicuous. Flowers are sweet and strong scented with nectar to attract What are Wind Pollinated Plants? Plants carry bisexual flowers Wind pollinated flower 1. (i) Characteristic features of anther, pollen and stigma of wind pollinated flowers: a. Anthers are usually versatile. [39] The flowers lack fragrance and nectar. Wind pollinated flowers possess the following characteristics : They are small and dull-coloured, often without petals. Animal pollinators play a crucial role in flowering plant reproduction and in the production of most fruits and vegetables. (8 marks) (c) Discuss Most plants require the assistance of pollinators to produce seeds and fruit. Examples of wind-pollinated flowers are corn, rice, and grasses. 3. Adaptations. a) Give illustrated description of a named flower, state its method of pollination. All unisexual flowers are cross-pollinated and even the bisexual […] Their stamens and stigmas are Meaning of Cross-Pollination 2. Q. Characteristics of animal pollinated flowers usually include all EXCEPT ... answer choices being large producing a lot of nectar producing less pollen being small Tags: Question 4 SURVEY 30 seconds Q. 8. The pollen grains are smooth, light and dry. Nectar and nectar guides are absent Stigmas are large, feathery and usually protrude out of the flower. Pollen grains are sticky so that they can stick easily to insect’s body parts. Explanation: Flowers can be wind-pollinated or animal-pollinated. 2. Since the question here did not mention anything about wind, high likely it is pollinated by animal and in here it is insect G, 0.5m for Pollinator, 0.5m for definition of pollination. 2. In wind-pollinated flowers, the produced pollen grains are smaller and lighter in weight, which can be carried by the wind easily. Characteristics of Insect pollinated flowers: 1. F. Wind-pollinated trees must grow in regions that are only moderately windy because strong winds will blow the tiny pollen grains past the stigma. Finally, it is proposed that geitonogamous selfing may alleviate pollen limitation in many wind-pollinated plants with unisexual flowers Discover the world's research 17+ million members They produce male sex cells and female sex cells.Insects can pollinate flowers, and so can the wind. They are not with attractive colours. In this system the flowers are such that the stamens form a tube around the immature style, with their pollen surfaces facing inward. Insect pollinated flowers are sticky,large with bright colors 2attract d insects,have scent,nectar,large petal for landing of insects. In wind pollinated flowers, pollination occurs by means of wind and this is known as anemophily. 2. Flowers are important for sexual reproduction by plants. [2] [3] It has recently been discovered that cycads , which are not flowering plants , are also pollinated by insects. Which one of the following characteristics of flowers … Characteristics of Rosales - Rosales - Characteristic morphological features: Members of Rosaceae are generally woody plants, mostly shrubs or small to medium-size trees, some of which are armed with thorns, spines, or prickles to discourage herbivores. Flowers may be solitary or as inflorescence 9. E. Wind-pollinated plants usually have small petalless flowers which often grow in catkins that produce a very fine-grained pollen. (ii) Stigmas are often large and feathery to easily trap the wind-borne pollen grains. Flowers are small and inconspicuous. Wind-pollinated flowers possess no bright colors, no special odors, and no nectar. Wind pollinated vegetation do no produce nectar whereas insect pollinated vegetation produce nectar which help them to attract bugs. 2. Wind-pollinated flowers do not produce scents or nectar; instead, they tend to have small or no petals and to produce large amounts of lightweight pollen. The flowers of chasmogamous species of Plantago have many characteristics related to wind pollination: strongly exserted stamens, abundantly produced smooth pollen grains, a reduced corolla, and a long, feathery stigma. Some aquatic plants like water hyacinth and water lily are insect pollinated.
