Both spend the majority of their time in the gametophyte stage. Both need wind for the gametes to unite. Both need wind for the gametes to unite. Both spend most of their time in the sporophyte stage. Both spend most of their time in the sporophyte stage. Both need water for the gametes to unite.
Both moss and fern reproduction share the similarity that they need water for the gametes to unite.
The structure that is the source of pollen in a plant is the anther.
The structure in a plant that acts as the source of pollen is the anther.
To understand this, we can refer to the floral structure of a typical flowering plant. The reproductive organs of a flower are known as the stamen and are composed of two parts: the filament and the anther. The filament is a slender stalk that supports the anther. On the other hand, the anther is a rounded structure located at the top of the filament and is responsible for producing and releasing pollen grains.
Pollen grains contain male reproductive cells and are necessary for the process of fertilization in plants. They are usually transferred from the anther to the female reproductive organ, called the stigma, through various means like wind, insects, or other pollinators.
Therefore, in a plant, the anther is the structure that serves as the source of pollen.
