SOME desert plant have spikes, which reduce the surface area of the leaves so that the loss of water is reduced.
desert, xerophytic plants
Their leaves are either needle like or reduced to spines so as to reduce water loss by evaporation. The function of the leaf is taken up by the stem which has cells containing chloroplasts to absorb light and also lenticels to absorb gases.By Mr. X Ycactus
they have a tolerance for salt waterLike Xerophytes, halophytes also possessSucculent leaves and stemThick walled and heavily cutinized epidermisHairy covering and mucilage cells.AdaptationsThe leaves are reduced to small scaly structures (Casuarinas) or spines (Opuntia)The leaves are shed when water is scarceWater storage structures develop in the leavesThey have a thick cuticle and a multiple layered epidermisThey have sunken stomataThey have long roots, which go in search of waterThe stem becomes green and takes over the function of photosynthesis where the leaves are absent/reduced/shed.
To protect it from predators in the desert.(: and to reduce the rate of transpiration. In many cases the thorn are formed by the modification of shoot , Thus eliminating the leaves hence the free surface to minimize the transpiration.)
clearly differentiated stem and leaves. -JH.
Yes, there are some plants in the desert with long leaves. A few examples:Palm treesYuccasSotol
The vast majority of desert plants do have leaves and few have only spines.
Yes
Leaves have evolved into spines on the cactus.
Yes, in the Desert the desert animals eat lots of cactus and other plants in the desert. In the sea the animals eat Kelp, seaweed, and etc.... And finally in the forest the animals eat either specific leaves or meat! Answered by: Anonymous
Small leaves minimize water loss.
