anther - style - stigma - ovary
anther - stigma - style - ovary
The correct answer is: "anther - stigma - style - ovary"
The correct answer is:
stamen - anther - pistil - ovary
To understand why this is the correct sequence, let's break down the different parts of a flower involved in the process of pollination:
1. Stamen: The stamen is the male reproductive organ of a flower. It consists of two main parts:
- Anther: The anther is located at the top of the stamen and contains the pollen grains.
2. Pistil: The pistil is the female reproductive organ of a flower. It consists of three main parts:
- Stigma: The stigma is the sticky top part of the pistil, which receives the pollen grains.
- Style: The style is the elongated tube-like structure that connects the stigma to the ovary.
- Ovary: The ovary is the lower part of the pistil, which contains the ovules.
Now, let's look at the given options:
1. stamen - pistil - anther - ovary: This sequence is incorrect because the anther, which contains the pollen, is part of the stamen, not the pistil.
2. stamen - anther - pistil - ovary: This sequence is correct. The anther releases the pollen, which then travels to the pistil for fertilization, specifically to the stigma, style, and eventually reaches the ovary.
3. anther - stigma - style - ovary: This sequence is incorrect because the stigma comes before the anther, and the style is located between the stigma and the ovary.
4. anther - style - stigma - ovary: This sequence is incorrect because the stigma should come before the anther.
Therefore, the correct answer is stamen - anther - pistil - ovary.
