Responses
stamen - anther - pistil - ovary
anther - stigma - style - ovary
anther - style - stigma - ovary
stamen - pistil - anther - ovary
anther - stigma - style - ovary
The correct answer is:
anther - stigma - style - ovary
The correct answer is: anther - stigma - style - ovary.
To understand why this is the correct path for pollen fertilization in a plant, let's break down the different parts involved:
1. Anther: The anther is part of the stamen, which is the male reproductive organ in a flower. It produces and holds the pollen grains.
2. Stigma: The stigma is part of the pistil, which is the female reproductive organ in a flower. It is the receptive surface where pollen grains land.
3. Style: The style is also part of the pistil. It serves as a tube connecting the stigma to the ovary.
4. Ovary: The ovary is the base structure of the pistil. It contains the ovules, which are the female reproductive cells.
Therefore, the complete path for pollen as it fertilizes a plant is from the anther (stamen) to the stigma (pistil), then through the style (pistil), and finally reaching the ovary (pistil) where fertilization can occur.
Out of the given options, the correct list that gives the complete path for pollen fertilization is "anther - stigma - style - ovary."
