Types of Pollination

Pollination is the process by which pollen grains are transferred from the male reproductive organs (anthers) to the female reproductive organs (stigma) of a flower, leading to fertilization and the production of seeds. There are different types of pollination, including:

1. Entomophilous Pollination (Insect Pollination): This type of pollination occurs when insects, such as bees, butterflies, and beetles, transfer pollen from the anthers to the stigma. Insects are attracted to flowers by their bright colors, fragrance, and nectar. They inadvertently pick up pollen on their bodies as they move from flower to flower in search of food. Many flowering plants, including apple trees, corn, figs, and hemp, rely on insect pollination for reproduction [[1]].

2. Anemophilous Pollination (Wind Pollination): In this type of pollination, the wind carries pollen from the anthers to the stigma. Plants that rely on wind pollination often have inconspicuous flowers with no bright colors or fragrance. They produce large quantities of lightweight, dry pollen that can be easily carried by the wind. Examples of wind-pollinated plants include birch trees, willows, and corn [[2]].

Classification of Plants

Now, let's determine the classification of the plants you mentioned:

- Watermelon (арбуз): Watermelon plants are entomophilous (insect-pollinated) plants. Insects, especially bees, play a crucial role in pollinating watermelon flowers [[1]].

- Apple tree (яблоня): Apple trees are also entomophilous (insect-pollinated) plants. Bees are the primary pollinators of apple trees, transferring pollen between flowers during their foraging activities [[1]].

- Corn (кукуруза): Corn is an example of a wind-pollinated plant. It relies on anemophilous pollination, as the wind carries the pollen from the tassels (male flowers) to the silks (female flowers) for fertilization [[2]].

- Aspen (осина): Aspen trees are wind-pollinated plants. They produce lightweight pollen that is dispersed by the wind to reach the female flowers for pollination [[2]].

- Hemp (конопля): Hemp plants are primarily entomophilous (insect-pollinated). Bees and other insects are attracted to hemp flowers for nectar and inadvertently transfer pollen between flowers [[1]].

- Fig (инжир): Fig trees are entomophilous (insect-pollinated) plants. They rely on specialized wasps for pollination, as the wasps enter the fig fruit to lay their eggs and inadvertently transfer pollen between flowers [[1]].

- Sea buckthorn (облепиха): Sea buckthorn is primarily wind-pollinated. Its flowers produce abundant pollen that is carried by the wind for pollination [[2]].

- Birch (береза): Birch trees are also wind-pollinated plants. They produce lightweight pollen that is dispersed by the wind for pollination [[2]].

- Weeping willow (повислая ива): Weeping willows are wind-pollinated plants. They produce large quantities of lightweight pollen that is carried by the wind for pollination [[2]].

Based on the information provided, the classification of the plants is as follows:

1) Watermelon (арбуз): Entomophilous (insect-pollinated) 2) Apple tree (яблоня): Entomophilous (insect-pollinated) 3) Corn (кукуруза): Anemophilous (wind-pollinated) 4) Aspen (осина): Anemophilous (wind-pollinated) 5) Hemp (конопля): Entomophilous (insect-pollinated) 6) Fig (инжир): Entomophilous (insect-pollinated) 7) Sea buckthorn (облепиха): Anemophilous (wind-pollinated) 8) Birch (береза): Anemophilous (wind-pollinated) 9) Weeping willow (повислая ива): Anemophilous (wind-pollinated)
