Cacti and Succulents
•Cacti and succulents have special structures to store water in thick fleshy leaves or stems
•Cactus is characterized by the presence of areoles, which often look like woolly cushions carrying
spines, hairs or glochids and the flowers arise from or near the areoles
•Spines in a cactus are modified leaves which provide shade against scorching sun and help in
conservation of moisture besides protecting against birds and animals
•Thrive best in sunny situations and are light loving
•Little care except when actively growing
All the cacti are succulents on account of storing water but all the succulents are not cacti
