Which structure is the source of pollen in a plant?
Sepal
Ovule
Anther
Style
The source of pollen in a plant is the Anther.
The structure that is the source of pollen in a plant is called the anther.
The structure in a plant that is the source of pollen is called the anther. To determine the answer to this question, you can recall the basic knowledge of flower structure or consult reliable sources such as botanical books or reputable websites.
In details, the anther is a part of the male reproductive organ called the stamen. It is typically located at the top of the stamen and is composed of pollen sacs, which contain numerous pollen grains. Pollen grains are the male reproductive cells of flowering plants that are responsible for fertilizing the female reproductive cells.
Other structures mentioned in the question, such as the sepal, ovule, and style, have important roles in the reproductive process of a plant but are not directly involved in pollen production. The sepal is the leaf-like structure at the base of a flower that protects the inner parts while the flower is still in bud. The ovule is the part of the plant that contains the female reproductive cell, and the style is the elongated structure that connects the ovary (which contains the ovules) to the stigma, where pollen grains typically land for fertilization.
