Even in absence of pollinating agents seed-setting is assured in

Options

A. Zostera
B. Salvia
C. Fig
D. Commelina

Answer

To solve the question regarding which plant can assure seed-setting even in the absence of pollinating agents, we can analyze the options provided:

1. **Zostera**: This is a marine grass that relies on water for pollination. Since it requires an external pollinating agent (water), it cannot produce seeds without it. Therefore, Zostera is not the correct answer.

2. **Salvia**: This plant is primarily pollinated by insects. Similar to Zostera, Salvia depends on an external pollinator for seed formation. Thus, Salvia is also not the correct answer.

3. **Fig**: The fig plant is pollinated by wasps. This means that, like the previous two options, it requires an external pollinator to produce seeds. Therefore, Fig is not the correct answer.

4. **Comelina**: Comelina produces clistogamous flowers, which are flowers that do not open. These flowers can self-fertilize without the need for external pollinating agents. As a result, Comelina can produce seeds even in the absence of pollinators.

Based on this analysis, the correct answer is **Comelina**.
