Autogamy means

Options

A. Transfer of pollen from anthers to stigma of the same flowers
B. Transfer of pollen from one flowers to another on the different plant
C. Occurence of male and female sex organ in the same flowers
D. Germination of pollen

Answer

**Step-by-Step Solution:**

1. **Understanding the Term "Autogamy":**
- Autogamy refers to a specific type of pollination process in plants. The term itself is derived from Greek, where "auto" means self and "gamy" means marriage or union.

2. **Definition of Autogamy:**
- Autogamy is defined as the transfer of pollen from the anthers (male part) to the stigma (female part) of the same flower. This means that the flower can fertilize itself without the need for pollen from another flower.

3. **Characteristics of Autogamous Plants:**
- Autogamous plants often have flowers that are not fully open, which helps in self-pollination.
- The reproductive parts (anthers and stigma) are positioned closely together, facilitating the transfer of pollen.
- These plants typically do not produce nectar, which is usually meant to attract pollinators.

4. **Examples of Autogamous Plants:**
- Common examples of plants that exhibit autogamy include sunflowers and orchids. These plants have adapted to self-pollinate to ensure reproduction.

5. **Advantages of Autogamy:**
- Autogamy ensures the passage of parental traits to the offspring, maintaining genetic consistency.
- It requires less energy since there is no need for pollen to be transported by external agents (like insects or wind).
- It leads to seed formation without relying on cross-pollination, which can be uncertain.

6. **Conclusion:**
- The correct definition of autogamy is the transfer of pollen from the anthers to the stigma of the same flower.

**Final Answer:**
- Autogamy means the transfer of pollen from anthers to the stigma of the same flower.
