Succulents

Succulents may store water in various structures, such as leaves and stems. The water content of some succulent organs can get up to 90–95%,^[2] such as Glottiphyllum semicyllindricum and Mesembryanthemum barkleyii.^[3] Some definitions also include roots, thus geophytes that survive unfavorable periods by dying back to underground storage organs (caudex) may be regarded as succulents. The habitats of these water-preserving plants are often in areas with high temperatures and low rainfall, such as deserts, but succulents may be found even in alpine ecosystems growing in rocky or sandy soil.
