Question

6. What are the advantages of leaves modified into spines in cactus plant.1 answer
​

Answer 1

Answer:

Most species of cacti have lost true leaves, retaining only spines, which are highly modified leaves. As well as defending against herbivores, spines help prevent water loss by reducing air flow close to the cactus and providing some shade. In the absence of leaves, enlarged stems carry out photosynthesis.

Answer 2

Explanation:

Most species of cacti have lost true leaves, retaining only spines, which are highly modified leaves. As well as defending against herbivores, spines help prevent water loss by reducing air flow close to the cactus and providing some shade. In the absence of leaves, enlarged stems carry out photosynthesis.To reduce loss of water through transpiration leaves of cactus plants are modified into spines.Widespread or very deep root systems that can collect water from a large area or from very deep underground. Spines which are modified leaves. These minimise the surface area and so reduce water loss. The spines also protect the cacti from animals that might eat them.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.
