Plant Adadptations: Cacti
The cactus plant has cool plant adaptations! Here are them (according to Succulent City)
The white spines are made up of dead cells at a mature age. This means they don’t take up water as it would have been the case if they were alive.
They trap air around the plant. This air provides a thin cover over the plant preventing water loss by evaporation and transpiration.
The spines, with their numerous number, add up to provide a considerable amount of shade for the plant. Such an adaptation lowers the temperature of the cactus surface which further reduces water loss.
In instances of fog/mist, the spines condense it into water droplets that fall off to the base of the plant where they are absorbed immediately.
