Best answer: Why maize flower is wind pollinated?

Maize flowers have evolved over time ,that is they have changed over time to use wind for pollination. They do not need pretty petals. The pollen is light so it can blow around and the ends of the female parts that are stigma are fluffy to catch all the tiny pollen grains. So, the correct answer is “Option C”.

Is maize a wind pollinated flower?

Maize mostly is wind-pollinated however maize pollen cannot be carried over very fairly lengthy distances by using wind, which essentially is quite massive. … The pretty male anthers commonly move in their pollen and it blows over to a nearby usually girl flower on any other corn plant in a kind of massive manner.

How is maize adapted to wind pollination?

They have versatile fixation of anthers so that they can swing freely with slight wind. The dehiscence of anthers is longitudinal and extrorse so that pollens can be easily taken to female flowers.

Is maize dispersed by wind?

Maize pollen is dispersed by wind (Messeguer, 2003) and its transference is affected by aspects related to the synchronicity of flowering periods, the isolation distance and climate conditions (Baltazar et al., 2005; Bannert and Stamp; . …

Which type of pollination occurs in maize?

Maize is predominantly cross pollinated. Wind pollination (Anemophily) is the general rule. Pollination by insects also takes place to certain extent.

Why is maize cross pollinated crop?

Maize produces a large number of pollen grains. Its pollen grains are non-sticky and can be transferred with the help of the wind currents. The stamens of maize are exposed so that the chances of trapping of pollen grains are maximized. So, the correct answer to the question is cross-pollination by wind.

What is maize flower?

Maize is a monoecious plant that produces male flowers on a terminal tassel (Fig. 1A) and female flowers on lateral ears (Fig. 1B), which arise in the axils of vegetative leaves. The tassel initiates several long, indeterminate branches at the base while the ear consists of a single spike with no long branches.

Which features in a maize plant suggest that it is pollinated by wind?

Large amount of pollen. Pollen smooth, light, easily airborne. Stigma feathery to catch pollen from wind. May have staminate and pistillate flowers, may be monoecious or dioecious.

Which flowers are pollinated by wind?

Wind Pollination (Anemophily)

Many of the world’s most important crop plants are wind-pollinated. These include wheat, rice, corn, rye, barley, and oats.

What is the pollination by wind called?

Anemophily is the process when pollen is transported by air currents from one individual plant to another. About 12% of the world’s flowering plants are wind-pollinated, including grasses and cereal crops, many trees, and the infamous allergenic ragweeds.

Is maize a cross pollinated plant?

Maize plants contain both male and female reproductive structures and reproduce by both cross-pollination and self-pollination.

Why is wind pollination common in plants like corn and wheat?

Wind-pollinating plants have no predisposition to attract pollinating organisms. … Anemophilous plants possess lengthy, well-exposed stamens to catch and distribute pollen. These stamens are exposed to wind currents and also have large, feathery stigma to easily trap airborne pollen grains.

Why wind pollinated flowers produce large amount of pollen grains?

In wind pollinated plants the chances of loss of pollen grains are more due to which most of the pollen grains fail to reach the appropriate stigma. So to compensate this loss and increase the chances of pollination the wind pollinated flowers produce large number of pollen grains.

Is maize self pollinated?

Domestication of Crop Plants

The majority of the 50–60 main grain crops of the world are predominantly self-pollinated. Only a few (such as maize, rye, pearl millet, buckwheat, or scarlet runner bean) are cross-pollinated. … A second advantage of self-pollination lies in the genetic structure maintained within the crop.
