Cactus (KAK-tus)
Cactus (pronounced: /ˈkæk.təs/; plural cacti /ˈkæk.taɪ/ or cactuses) is a type of plant that belongs to the family Cactaceae. The term "cactus" is derived from the Ancient Greek word κάκτος (kaktos), which was used to describe a type of spiny plant.
Etymology
The word "cactus" is derived from the Ancient Greek κάκτος (kaktos), which was originally used to describe a type of spiny plant. The term was later adopted by Carl Linnaeus in his botanical nomenclature to refer to a group of flowering plants known for their spiny appearance.
Description
Cacti are known for their distinctive appearance, which includes thick, fleshy stems that are adapted to store water. These plants are typically found in arid and semi-arid regions, such as deserts. Cacti are also characterized by their spines, which are modified leaves that serve to deter herbivores and provide shade to the plant.
