Which list gives the complete path for pollen as it fertilizes a plant? (1 point.)
Answers:
anther - style - stigma - ovary
anther - stigma - style - ovary
stamen - pistil - anther - ovary
stamen - anther - pistil - ovary
anther - stigma - style - ovary
The correct answer is: anther - stigma - style - ovary.
To determine the correct answer, let's break down the process of pollen fertilizing a plant.
Pollen is produced in the anther, which is part of the stamen. The stigma is the receptive surface where the pollen must land in order to initiate fertilization. The style serves as a pathway for the pollen to travel from the stigma to the ovary. Finally, the ovary contains the ovules, which are ultimately fertilized by the pollen.
Now, let's look at the options given:
1. anther - style - stigma - ovary: This option follows the correct order from the production of pollen in the anther to its transfer to the stigma via the style, and finally to its fertilization of the ovary. Hence, it is a potential correct answer.
2. anther - stigma - style - ovary: This option reverses the order of the style and stigma. The pollen needs to travel through the style to reach the ovary, so this is not the correct sequence.
3. stamen - pistil - anther - ovary: This option replaces specific terms like "anther" and "style" with broader terms like "stamen" and "pistil." While a stamen contains an anther, it does not provide a detailed sequence for pollen fertilization. Therefore, this is not the correct answer.
4. stamen - anther - pistil - ovary: Similarly to the previous option, this choice uses the broader terms "stamen" and "pistil" instead of the individual components involved in pollen fertilization. Therefore, this is not the correct answer.
In conclusion, the correct answer is the first option:
anther - style - stigma - ovary.
