Plants that producewind-blown pollen, many of which are trees, make life miserable for millions of human allergy sufferers each year. A large number of tree species produce extremely small pollen particles from their male sexual parts. These trees use the wind as their favorite means of pollen...
Moreover, the arrangement of the flower’s internal organs is often such as to compel the insect to become smeared with pollen in order to reach its food; when the insect visits another flower, it is pollinated by insects, and among these so-called entomophilous flowers are the zygomorphic...
Pollinationis the first required step in sexual reproduction in plants. The male portion of the plant produces the pollen – typically in the flower. A long filament, called a stamen, holds the bits of pollen at the end and one of several pollinators take the pollen grains to the ...

There are many different types of pollinators though most pollinator species are insects. These insects often obtain their nutrients from the nectar that is produced in the base of flowers, which means they have to pass by the pollen-carrying anthers to access it and thereby become covered in...
Pollination is one of nature's ways of plant reproduction. Learn how the different types of pollination, including cross-pollination and...
Reproduction is the biological process of producing offsprings that are biologically or genetically similar to the parents. Explore more about different types of reproduction only @ BYJU'S.
When pollination occurs in a flowering plant, the male pollen enters the female ovary containing female ovules. The female plant ovule then matures into a seed. Seed production also creates fruits. Seeds are essential to plant survival because they create new plants. ...
What are the characteristics of conifers? Conifers: Conifers are some of the more rugged species of trees and shrubs. They are found in every part of the world except on the continent of Antarctica. They are also able to grow at higher altitudes than deciduous trees and shrubs. ...
Metrics that focus on specific colony functions such as increased brood or forager mortality are ineffective indicators for all types of simulated pesticide effects. At the levels of colony loss recommended by EFSA, using our default parameterization, we predict a loss of ecosystems performance of 3%...
