A bee will pollinate a flower if it moves pollen from (1point)
O the sepal to the pedicel.
O the anther to the stigma.
O the pistil to the stamen.
O the filament to the style.
The correct answer is:
- the anther to the stigma.
A bee will pollinate a flower if it moves pollen from the anther to the stigma.
To determine which option is correct, we need to understand the anatomy of a flower and the process of pollination.
The parts of a flower involved in pollination are the male reproductive organ called the stamen and the female reproductive organ called the pistil.
The stamen consists of two main parts: the anther and the filament. The anther produces pollen, which contains the male gametes or sperm cells. The filament holds up the anther.
The pistil consists of three main parts: the stigma, the style, and the ovary. The stigma is the tip of the pistil, which is sticky and receptive to receiving pollen. The style connects the stigma to the ovary, which contains the female gametes or egg cells.
Now, back to the question. A bee will pollinate a flower by moving pollen from one part of the flower to another.
Option O - "the sepal to the pedicel" is incorrect because the sepal is the leaf-like structure that protects the flower bud, and the pedicel is the stalk that connects the flower to the stem. Neither of these parts are directly involved in pollination.
Option O - "the pistil to the stamen" is also incorrect because the pistil is the female reproductive organ, and the stamen is the male reproductive organ. Pollination occurs when pollen is transferred from the stamen (specifically, the anther) to the pistil (specifically, the stigma).
Option O - "the filament to the style" is incorrect because the filament is part of the stamen, and the style is part of the pistil. Pollination does not involve transferring pollen between these two parts.
Therefore, the correct answer is option X - "the anther to the stigma." Bees, along with other pollinators like butterflies and hummingbirds, collect pollen from the anther and inadvertently transfer it to the stigma while moving from flower to flower. This transfer of pollen enables fertilization and ultimately leads to the production of seeds and fruits.
