why are leaves reduced to spines in desert plants?
Answers
loss of water takes place to control that leaves are converted into spines.
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.
Explanation:Spines - some plants have spines instead of leaves eg cacti. Spines lose less water than leaves so are very efficient in a hot climate. Spines also prevent animals from eating the plant. ... This reduces water loss by transpiration .
. desert plants like cactus have spines on their body to store water in themselves if it would have leaves then transpiration would take place and it would lead to loss of water but in deserts there is lack of water.
