What are the characteristics of water and insect pollinated flowers?

Expert Answer:

• Characteristics of Insect pollinated flowers:
• Large and coloured petals to attract insects.
• Nectar to attract insects.
• Pollen grains are sticky so that they can stick easily to insect’s body parts.
• Characteristics of water pollinated flowers:
• Stamens and pollen grains are spongy and water-proof.

What are the characteristics of wind and water pollinated flowers?

I) Both wind and water pollinated flowers are very colourful and produce nectar. II) Wind-pollinated flowers have large feathery stigma to easily trap air-borne pollen grains. III) Flies are the dominant biotic pollinating agents.

What are the adaptations in water pollinated flowers?

iii Stigma long and sticky. iv Female flowers reach the surface of water. v Male flowers are also released on the surface of water so that they may be carried through water currents to the stigmas of female flowers to effect pollination at the water surface as it Vallisneria.

Which of the following is a characteristic of pollinated flowers?

Complete answer: 1) Flowers are brightly colored, scented, and secrete nectar. 2) Pollen grains are larger, sticky, and spiny. 3) Pollen grains are fewer in number as they are transported mechanically by insects. 4) The stigma of flowers is small and deep within the corolla.

Which characteristics of water pollinated species of pollen grains protect them from water?

Pollen grains of water pollinated species have a special characteristic for protection from water is the presence of mucilaginous layer. They have a mucilagenous covering that protects them from wetting.

What are the characteristics of wind water and insect pollinated flowers Class 12?

What are the characteristics of wind ,water and insect pollinated…

• Large production of pollen grains.
• The anther is well exposed.
• are not attractive and scent emitting.
• Feathery and sticky stigma.
• Flowers do not possess nectar.

What are water pollinated plants?

Water pollinated plants are aquatic. Pollen floats on the water’s surface drifting until it contacts flowers. This is called surface hydrophily, but is relatively rare (only 2\% of pollination is hydrophily). Most aquatic plants are insect-pollinated, with flowers that emerge from the water into the air.

What kind of pollination occurs in water hyacinth and water lily?

wind
In water hyacinth and water lily, pollination takes place by wind and insects. Both water hyacinth and water lily have conspicuous attractive petals to facilitate insect pollination. Along with the attractive petals, some of these species produce many pollen grains to aid anemophily or wind pollination.

Which of the following is characteristic of flower?

Flower is a reproductive organ of the angiosperm plant that contains thalamus and floral leaves. A typical flower consists of four types of floral leaves called sepals, petals, stamens and carpels in distinct whorls normally known as calyx, corolla, androecium and gynoecium respectively.

What plants are pollinated by water?

Water-Pollinated Plants

• Common Waterweed. Common waterweed (Egeria densa), also called Brazilian elodea, is originally native to the coasts of Argentina, Brazil and Uruguay, and is now found throughout North America.
• Pond Weed.
• Eel-grass.
• Hydrilla.
• Coontail.
• Vallisneria.

What would be the reason for wind and water pollinated flowers are not very Colourful and do not produce nectar?

These two agents are light in weight as the air and water cannot carry the heavy pollen. Insects get attracted towards the nectar and flower but here in the wind and the water it does not occur. So, this is the reason why wind pollinated and water pollinated flowers are not colorful and they cannot produce nectar.

Are water plants pollinated by water?

Pollination in water plants is carried out by water, wind or insects. Pollination by water occurs in a selected number of plants, e.g. Vallisneria, Hydrilla and Zostera (seagrass), etc. Most of the aquatic plants are pollinated by wind or insects, e.g. water hyacinth, water lily.

What is a water-pollinated plant?

Plants that are water-pollinated usually have small, inconspicuous male flowers that release lots of pollen grains that drift in the water where they are caught by the large, feathery stigmas of female flowers. Sciencing_Icons_Science SCIENCE

What are the characteristics of pollinated flowers?

The stalks of the pollinated flowers are usually very long to project their stigmas above the water surface. No animal transporters are needed for pollination. The flowers need not to be colourful (no need to attract) and generally white in colour. Was this answer helpful?

What does a wind pollinator plant look like?

Wind pollinator flowers may be small, no petals, and no special colors, odors, or nectar. These plants produce enormous numbers of small pollen grains. For this reason, wind-pollinated plants may be allergens, but seldom are animal-pollinated plants allergenic. Their stigmas may be large and feathery to catch the pollen grains.

Why are the stigmas of the pollinated flowers large and feathery?

The stigmas are large and feathery to catch the pollens. The male flowers after maturation get detached from the plant and float above the water surface. The stalks of the pollinated flowers are usually very long to project their stigmas above the water surface.
