Plants need butterflies for two main reasons such as pollination. Plants also need butterflies to bring other animals into the ecosystem.
plants form new plants by pollination of each other
Cross Pollination is when the flower/plant is pollinated by other flowers/plants other then its self, unlike Self Pollination which ONE flower/plant can pollinate its self with out other flowers/plants, the more you learn in BIO the more you can see the hand of God in work!
Bees (and other flying insects) are needed for the pollination of fruit, flowers, trees and various other plants. Without pollination, plants couldn't survive and we wouldn't have enough food to eat.
Pollination. Pollination can occur from the same plant, or from other plants of the same species. The pollen can be spread by wind, animals, or insects (notably bees).
To attract bees, moths and other insects to achieve pollination
Mendel was interested in the offspring of two different parent plants, so he had to prevent self-pollination. He removed the anthers from the flowers of some of the plants in his experiments. Then he pollinated them by hand with pollen from other parent plants of his choice. When pollen from one plant fertilizes another plant of the same species, it is called cross-pollination.
Having the ovules out of reach from the other.
Sexual reproduction occurs in plants by the process of pollination. Insects come and collect pollen from the plants that then travel to other plants pollinating them.
yes you can. if you plant a plant after awhile it will produce other plants from pollination. if they are seasonal plants then it will NOT work. other house plants don't do this either. so do plants from Wal-Mart.\\\\\\\\\\\\\\\\\\\\\
Other than bees and humans for watering them, plants can live off of rain and sunlight.
Plants that do not require external help to transfer their pollen are known as self-pollinating plants. Peanuts belong to this category and reproduce by dropping old flowers to the ground on growing old. These flowers release their pollen at sunrise and start fertilizing eventually.
