Question

Mention the unique feature with respect to flowering and fruiting in bamboo species.

Answer 1

Hint: Bamboo grows like a plant for a period of time before it blooms, sows, and dies. Most bamboo plants only flower once during their life cycle. It means bamboo species are Monocarpic. Bamboo flowers are rare and unpredictable, and the flowering frequency varies greatly from species to species. After flowering, the plant falls off and often dies completely. In fact, many species only cost $50$ flowers to $100$ . Bamboo species exhibit mass flowering

Complete answer:
A feature unique to flowering and fruiting of bamboo is that it blooms only once in its life, bears many fruits and dies.
There are various hypothesis which explains mass flowering of bamboo species these are:
One of the hypotheses explaining the occurrence of this phenomenon of mass flowering is the hypothesis of predators, which increases the resistance of seeds due to flooding of the territory with fruits simultaneously with the fruiting of the population. Another hypothesis, known as the fire cycle hypothesis, is that after periodic flowering, the death of mature plants became a habitat disruption mechanism, leaving space for the seedlings to grow. However, both are controversial for a number of reasons. The predator saturation hypothesis does not explain why the flowering cycle is $10$ times longer than the unpredictable initial lifespan of rodents.

Additional information:
Strobilanthes kunthiana, or neelakurinji is a shrub native to the Shola forests on the mountain trails of southern India. Nilgiri Hill, which literally means "blue mountain", gets its name from the purple-blue Neelakurinji flower that blooms only once every $12$ years.

Note: This slow blooming species exhibits other strange behaviours as well. If it comes from the same parent plant, it blooms at the same time worldwide, regardless of geographic location or climate. Most bamboos are just like that. They are "parts" of each other of the same parent plant. These departments have over time been divided and distributed around the world. The branches are now geographically distinct, but still have the same genetic makeup. For example, if bamboo is blooming in North America, the same plant will do the same in Asia at the same time. It's like a factory internal clock that ticks until a present alarm goes off at the same time. This phenomenon of mass flowering is called gregarious flowering. The sudden death of large areas of bamboo puts pressure on animals that depend on bamboo for food, such as the endangered giant panda. Many species of bamboo, including Guadua angustifolia, are indigenous and can grow from time to time. When individual plants bloom sporadically, they rarely die, but most seeds cannot survive.
