GENERAL KNOWLEDGE

Detailed explanation-1: -Cactuses, or cacti, are desert plants. They grow in dry places where other plants have trouble living. Their ability to store water keeps them alive. Cacti are also protected by sharp spines, or needles.

Detailed explanation-2: -Ans: Desert plants like Cactus, Agave or Mesquite have to survive in deserts where the water is very scarce.
