How cacti survive in the desert: secrets of their natural armor.

According to ТСН: The name of cacti comes from the Latin word 'succus', which means 'juice', as their main water reservoir is hidden inside the fleshy stem. In desert conditions, where rain is a rare occurrence, and the scorching sun quickly evaporates moisture, cacti adapt to extreme conditions. They cover their stems with a thick skin and waxy coating, serving as natural protection against heat.

However, the most potent defense mechanism of cacti is their spines.

Adaptation of spines

Once, spines were leaves that eventually evolved into hard, sharp thorns. This is an ideal defense mechanism. Spines protect the plant from animals that, in drought conditions, are ready to devour anything containing water. Thus, cacti are covered with various thorns — long and short, white and yellow, straight and hooked. Each type of thorn plays an important role in the survival of the plant.

Functions of spines

Aside from protection, spines also reduce evaporation and partially shade the stem, creating a unique microclimate around the plant.

Interestingly, people have long used this natural 'armor': dense thickets of cacti are made into living fences, and desert travelers have often saved themselves from thirst by using their stems.

Cacti are not only amazing plants but also important elements of the ecosystem in arid regions. Their ability to survive in conditions where other plants simply cannot makes them true champions of adaptation. They not only provide the necessary moisture for animals and people in deserts but also contribute to the formation of natural landscapes.
