Exploring the Fascinating World of Cacti

Cacti are specialized plants adapted to arid environments. Their thick, fleshy tissues store water. Spines, which are modified leaves, offer protection and reduce water loss by shading the plant.

Some cacti can live for over 200 years. The Saguaro cactus, a symbol of the American desert, can grow to over 40 feet and doesn't reach maturity until 70-100 years.

Certain cacti bloom at night to attract nocturnal pollinators. The magnificent Selenicereus grandiflorus, or Queen of the Night, unfurls its flowers after dark, relying on bats and moths for pollination.

While cacti are synonymous with deserts, they also thrive in rainforests. Epiphytic cacti, like the Christmas Cactus, grow on trees and derive moisture from the humid air.

Cacti can survive long droughts. They convert carbon dioxide into malate at night, storing it until daylight for photosynthesis, a process called CAM photosynthesis, which is highly water-efficient.

Cacti are crucial in desert ecosystems. They provide food, water, and shelter for many creatures. Their flowers and fruits are particularly important for local wildlife.

Not all cacti are thriving; some are endangered due to habitat loss, over-collection, and illegal trade. The rarest, like the Ariocarpus bravoanus, are protected under CITES to prevent extinction.

Some cacti can explode from overwatering, causing their tissues to rupture due to excessive internal pressure.
