Question

Give two ways in which spines help the cactus survive in a desert.​

Answer 1

Answer:

Spines help cacti to thrive in desert environments by providing multiple functions. They protect the plant from predators, provide shade, help regulate temperature, reduce water loss and even help the plant to spread and reproduce.

The spines on a cactus help to protect it from humans and animals. Its roots are spread out to collect water when it does rain and it stores water in its body for future use. An expert explains how a cactus can survive for years between rainstorms by living off the water it stores.

Answer 2

The two ways by which the spines of the cactus help it to survive are given below.

Explanation:

• The cactus is adapted to survive in a hot and warm climate such as deserts and dry regions.
• Thus, the leaves of the cactus are modified into pointed spines, by which they prevent the heavy loss of water by transpiration.
• The second thing is that the spines help the cactus to keep away the humans or other animals from being touched.
• The cactus is very moist from the inside and any human or traveller who is seeking water in the desert can eat the cactus.
