Question:
Which of the following is an example of vivipary?
Which of the following is an example of vivipary?
Show Hint
Vivipary = "Live birth." In plants, think of mangroves like Rhizophora that grow their "babies" before letting them go.
Updated On: May 5, 2026
- Rhizophora
- Opuntia
- Bryophyllum
- Agave
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
Vivipary in plants refers to the germination of seeds while they are still attached to the parent plant, before being dispersed.
Step 2: Meaning
This is an adaptation often found in mangrove plants to survive in saline, anaerobic (oxygen-poor), and waterlogged marshy soils where normal germination is difficult.
Step 3: Analysis
Opuntia (cactus) and Agave do not show this trait. Bryophyllum shows vegetative propagation through leaf buds, which is different from seed vivipary. Rhizophora, a common mangrove tree, allows the seedling to grow a long hypocotyl while attached to the parent.
Step 4: Conclusion
Once the seedling is heavy enough, it falls and anchors itself in the mud, making Rhizophora the classic example of vivipary. Final Answer: (A)
