The correct list that gives the complete path for pollen as it fertilizes a plant is:
1. anther - stigma - style - ovary
The correct list that gives the complete path for pollen as it fertilizes a plant is:
anther - stigma - style - ovary
To understand why this is the correct answer, we need to have a basic understanding of plant reproduction.
In flowers, the stamen is the male reproductive organ and consists of two main parts: the filament and the anther. The anther is where the pollen is produced. The pistil, on the other hand, is the female reproductive organ and consists of three main parts: the stigma, style, and ovary.
When pollen is released from the anther, it needs to reach the ovary of the pistil in order to fertilize the plant. This happens through a process called pollination. The pollen grains are carried by different mechanisms, such as wind, insects, or other animals, to the stigma, which is the sticky structure located at the top of the pistil. The stigma serves as a landing platform for the pollen.
Once the pollen grains land on the stigma, they germinate and grow a tube called the pollen tube. The pollen tube will then grow down the style, which is a long, narrow part of the pistil, toward the ovary. The pollen tube contains the sperm cells, which will eventually reach the ovary and fertilize the ovules inside.
Therefore, the correct order of the path for pollen as it fertilizes a plant is anther - stigma - style - ovary.
