12The researchers are fascinated with the structure and shape of bee stigmas, the feminine organs responsible for harvesting and transmitting pollen. Aware of the bees' pivotal role in plant reproduction, they seek to decode how the distinct traits of bee stigmas enhance their competence in pollination. The hypothesis put forward by the researchers suggests that extended bee stigmas enhance the efficiency of bees in amassing and disseminating pollen. They initiated an extensive investigation comparing diverse bee species boasting different stigma configurations to substantiate their proposition. The researchers meticulously examined the volume of pollen clinging to the stigmas post the bees' visitation to specific plant species.12 Mark For Review12Which finding, if true, would most directly support the researcher’s hypothesis?A) Pollen from a particular flower species was transferred more effectively by local bees compared to other floral types.B) The extended stigmas tend to fracture more effortlessly than the shorter ones due to a heightened moment of inertia.C) Bees possessing stigmas with reduced and more readily accessible structures exhibit a significantly augmented pollen load compared to bees with protracted stigmas.D) Bees with stigmas with elongated, branched, and complexly folded configurations demonstrate a considerably increased pollen haul compared to bees with simpler, abbreviated stigmas.

Explain how the structure and function of pollen allow bees to help with plant reproduction.

What is the main idea of this text?Pollination causes plants to reproduce fruits and seeds because it is when the stamen, or male part, of a flower is moved to the stigma, or female part, of a flower and the plant is fertilized.Hummingbirds and butterflies are examples of animals that are pollinators that we may overlook in our daily lives, but they have a very important role in plant and crop reproduction.Pollinators play an important role in making sure many flowering plants and food crops can grow, and because their populations are declining, humans are working to protect them.In 2010, honey bees and other insect pollinators contributed to tens of billions of dollars of crop production in the United States and their populations are declining due to various factors.

Bees are insects known for their production of honey (in some species) and their role in the pollination process. They are found in every global habitat that has insect-pollinated flowering plants, and they play an important role in those ecosystems. Some countries have a higher prevalence of domesticated bees and some have more wild bees. A laboratory has conducted a study of different ecosystems which rely on bee pollination and concluded that wild bees play a more efficient role in pollinating an ecosystem as compared to domesticated bees. Which finding from the laboratory study, if true, would most directly support their conclusion?Domesticated bees pollinate a wider variety of flowers than wild bees do. eliminateSince honey reserves are collected from domestic hives by beekeepers, the bees must collect more pollen from flowers to produce more honey.eliminateThe success of urban gardens is directly related to the number of wild, urban bee hives in the area.eliminateWild bees were found to visit 50% more plants than domestic bees were in the same time frame.

What is the function of the stigma on a flower?A.It provides a supply of stored nutrients for the seed.B.It helps spread seeds away from the parent plant.C.It has a sticky surface that helps trap pollen grains.D.It attracts birds, bees, and bats to help with pollination.SUBMITarrow_backPREVIOUS

Determine how bees help plants to reproduce.By depositing nutrients, which helps plants grow bigger and strongerBy collecting nectar and producing honeyBy collecting seeds and depositing them where new plants can growBy depositing pollen, which helps plants produce seeds
