Answer:
Simultaneous Growth and Maturation of Anthers and Stigma
In some plants, the anthers and stigma grow and mature at the same time. This phenomenon is called homogamy.
Homogamy
Homogamy is a botanical term used to describe the condition in which the anthers and stigma of a flower mature at the same time. In other words, homogamy refers to the synchrony in the development of the male and female reproductive organs in plants.
Types of Homogamy
There are two types of homogamy:
1. Protandry: In protandry, the anthers mature first, followed by the stigma.
2. Protogyny: In protogyny, the stigma matures first, followed by the anthers.
Advantages of Homogamy
Homogamy provides several advantages to plants:
1. Increased chances of pollination: Since the anthers and stigma mature at the same time, there is a higher likelihood of pollination occurring.
2. Reduced self-pollination: In plants with homogamy, self-pollination is less likely to occur, which promotes outbreeding and genetic diversity.
Examples of Homogamous Plants
Some examples of homogamous plants are:
1. Maize
2. Cucumber
3. Melon
4. Tomato
Conclusion
Homogamy is a condition in which the anthers and stigma of a flower mature at the same time. This phenomenon provides several advantages to plants, including increased chances of pollination and reduced self-pollination. Some examples of homogamous plants are maize, cucumber, melon, and tomato.

Homogamy in Plants
Homogamy is a phenomenon observed in flowers of some plants where the anthers and stigma mature at the same time. It is also known as synchronous dichogamy.
Explanation:
- Homogamy is the opposite of dichogamy, which is the temporal separation of the anther and stigma maturation in a flower.
- In homogamous flowers, the anthers and stigma mature simultaneously, which ensures efficient self-pollination.
- Homogamy is a common trait in many plant families, including legumes, grasses, and orchids.
- The anthers and stigma in homogamous flowers may be positioned closely together, making self-pollination more likely.
- The advantage of homogamy is that it ensures reproductive success in plants that lack pollinators or in environments where pollinator activity is limited.
- Homogamy can also be advantageous in situations where the plant population is small, and cross-pollination opportunities are limited.
Examples of Homogamous Flowers:
- Legume flowers, such as those of peas and beans, are homogamous.
- Orchids are also homogamous, with their anthers and stigma located close together in a structure called the column.
- Grasses, including corn and wheat, are homogamous, with their flowers having both male and female reproductive organs.
Conclusion:
Homogamy is a phenomenon observed in some plants where the anthers and stigma mature at the same time. It ensures efficient self-pollination and is advantageous in plants that lack pollinators or in environments where pollinator activity is limited. Homogamous flowers are found in many plant families like legumes, orchids, and grasses.
