What are advantages of leaves modified into spines in cactus plant?
Leaves of cactus plants are modified into spines to reduce loss of water through transpiration.
Are modified into spines in?
In pea, the leaves are modified into tendrils to help them in climbing around support, in onion leaves are modified to fleshy succulent to store food. Leaves are modified into spines in Opuntia (xerophytes) so as to reduce the surface area and minimize rate of water loss by evaporation and transpiration.
What is the purpose of a modified cactus?
The leaves of cactus plant are modified into spine because it helps them to lose less water during transpiration and also protect from beings eaten by animal.
Why are leaves modified into spines in prickly pear?
Leaves of certain plants become wholly or partially modified for defensive purpose into sharp, pointed structures known as spines. Thus, in prickly pear the minute leaves of the axillary bud are modified into spines. … Their function is to protect the axillary bud that they bear in their axil.

Additionally, aloe vera leaves can use an adapted photosynthesis pathway to generate energy.
Why are leaves modified into spines?
Leaf spines to provide protection and reduce the loss of water: In certain plants, leaves or parts of leaves get modified into pointed structures called spines. Spines help to reduce the loss of water by transpiration. They also protect the plant from grazing animals.
