Flowering plants have evolved two pollination methods: 1) pollination without the involvement of organisms (abiotic), and 2) pollination mediated by animals (biotic). The majority of plant pollination is done by animals. insects. Pollination by insects is the most efficient way to pollinate a plant, but it is not the only way. Insects can also be used as pollinators.
For example, the honeybee (Apis mellifera) and the wasp (Hymenoptera: Formicidae) are both capable of pollinating flowers. In fact, honeybees and wasps are considered to be the two most important pollinator species on the planet.

How does pollination occur in angiosperms?
The pollen bursts forth from the pendulous inflorescences as they sway in the wind. Some of the living unspecialized families of angiosperms are pollinated by bees. Angiosperm pollination is important for the survival and reproduction of many species of plants and animals. It is also important to the health and well-being of humans and other animals that depend on pollinating plants for food, shelter, and protection.
How do plants attract insects for pollination?
Plants produce nectar to attract pollinators. As the pollinator moves from flower to flower, they are also moving the pollen from flower to flower. If flowers are not pollinated, certain fruits and seeds will not be produced. Pollination is the process by which pollen is transferred from one plant to another.
Pollination occurs when a pollen-carrying insect, such as a bee or wasp, attaches itself to the pollen of another plant. When a plant receives pollen, it begins to grow and produce fruit.
Which of the following strategies are used for cross-pollination?
Self-incompatibility is a genetic mechanism that prevents self-pollen from fertilising the ovules or retarding the growth of the pollen tube. The plant is able to produce both male and female flowers by producing unisexual pollen. In the case of a female plant, this means that the pollen produced by the male flower will not fertilise the female flower, and vice versa.
This is known as the’self-fertilisation’ principle. The female plants produce pollen that can be passed on to the next generation of plants. However, it is not possible for a male plant to pass on his pollen to another male, as this would be a violation of his own genetic code.
How does a butterfly help in pollination a lily flower?
Flower petals are leaves that develop inside a bud and are modified to assist in the reproduction process. The lilies’ primary pollination assistants are butterflies and bees. Insect helpers jump from flower to flower, carrying pollen from the mother plant to the developing flower. Lily of the Valley is one of only a handful of flowering plants in North America that can be used as an insect pollinator.
In fact, it is the only flowering plant that has been used for this purpose by humans for thousands of years. The plant is native to China, Japan, Korea, and Taiwan. It is also found in parts of South America, Africa, Australia, New Zealand, Europe, Asia and the Middle East.
Which flowers are pollinated by moths?
Science has only recently begun to uncover the efforts of the moths, who were known to pollinate flowers at night. The types of flowers they visit are pale-coloured flowers with an open cup or tubular shape, such as creeping buttercup or honeysuckle, which are known to attract moths.
Moth caterpillars, on the other hand, feed on a wide range of plant species, including those that are not pollinated by butterflies. They are also attracted to the scent of rotting fruit so they can be found feeding on apples; (Check list below)
- Other fruits
as well as nuts
Moths can also be attracted by the odour of urine and faeces.
