Which list gives the complete path for pollen as it fertilizes a plant?
a. stamen-anther-pistil-ovary
b. anther-stigma-style-ovary
c. anther - style-stigma-ovary
d. stamen-pistil-anther-ovary
b. anther-stigma-style-ovary
The correct answer is: b. anther-stigma-style-ovary
To determine the correct answer, we need to understand the parts of a flower involved in pollination and fertilization. Pollen is produced in the anther, which is a part of the stamen. The pollen must then be transferred to the stigma. From there, it moves down the style and reaches the ovary, where fertilization occurs.
Now, let's analyze the given answer choices:
a. stamen-anther-pistil-ovary: This order is incorrect because the anther is part of the stamen, so it should not be listed separately.
b. anther-stigma-style-ovary: This order correctly follows the path of pollen. It starts with the anther, moves to the stigma, then the style, and finally reaches the ovary. This option seems plausible.
c. anther-style-stigma-ovary: This order incorrectly places the style before the stigma, which is not accurate.
d. stamen-pistil-anther-ovary: This order lists the anther after the pistil, which is incorrect. The anther is part of the stamen, not the pistil.
Based on the analysis, the correct answer is:
b. anther-stigma-style-ovary
This order follows the path of pollen as it fertilizes a plant.
