Question

Which of the following occurs during pollination in angiosperms?

A- Pollen grains are transferred from the stamen's anther to the pistil's stigma.

B- Pollen grains are transferred from the stamen's filament to the pistil's stigma

C- Pollen grains are transferred from the pistil's anther to the stamen's stigma.

D- Pollen grains are transferred from the stamen's stigma to the pistil's flagment.​

Answer 1

A- Pollen grains are transferred from the stamen's anther to the pistil's stigma.

Step-by-step explanation:

• An angiosperm is a vascular flowering plant. The flowers contain both male reproductive organ and a female reproductive organ.
• The male part is made up of the anthers and filament. The anthers contain pollen grains which fertilize the female reproductive part through the process of pollination.
• The female reproductive part has the stigma,style and the ovary. The stigma is sticky to enable sticking of pollens grains during pollination and the style develops a tube that transports them down to the ovary for fertilisation.
