Explanation:
- The correct answer to this question is option A, Bamboo Species.
- Bamboo is a type of grass that belongs to the family Poaceae.
- Unlike other flowering plants, bamboo species have a unique reproductive cycle where they flower only once in their lifetime.
Life Cycle of Bamboo:
1. Vegetative Stage:
- Bamboo starts its life as a small shoot emerging from the ground.
- During this stage, the plant focuses on growing its stem, leaves, and roots, and does not produce flowers.
2. Reproductive Stage:
- After a certain period, which can range from several years to several decades depending on the species, the bamboo enters the reproductive stage.
- During this stage, the plant allocates its energy towards the production of flowers and seeds.
3. Flowering Stage:
- When a bamboo species reaches its flowering stage, it produces flowers on its branches.
- The flowers are typically small and inconspicuous, and they are arranged in clusters known as inflorescences.
- The flowers of bamboo are usually wind-pollinated.
4. Seeding Stage:
- After the flowers are pollinated, they develop into seeds.
- The seeds are dispersed by wind or animals to new locations where they can germinate and grow into new bamboo plants.
5. Senescence Stage:
- Once the bamboo has produced flowers and seeds, it enters a stage known as senescence.
- During this stage, the bamboo plant gradually dies.
- After the flowering and seeding process is complete, the bamboo species dies back to the ground, and new shoots emerge to begin the cycle again.
Conclusion:
- In conclusion, the bamboo species only flowers once in its lifetime during the reproductive stage.
- This unique flowering pattern is one of the distinguishing characteristics of bamboo and sets it apart from other flowering plants like jackfruit, mango, and papaya, which can produce flowers multiple times throughout their lifespan.
