Spines are better than leaves in the desert primarily because they reduce water loss by minimizing surface area and providing shade to the plant. They also help deter herbivores from consuming the plant, which is crucial in a harsh environment where resources are scarce. Additionally, spines can reflect sunlight, further reducing heat absorption and helping the plant maintain its internal temperature. Overall, spines enhance a plant's survival in the extreme conditions of the desert.
Cacti have spines that evolved from leaves.
aloes normally have short, hard (sometimes black) spines on the leaves and sometimes the stems - although they cannot really be likened to black thorns
just go outside look at the trees with leaves on them and you will see leaves or go outside in the fall.duh.........1.orange leave 2.green leave 3.red leave ect.there are lots of leaves more than just thesethere are different shapes as well and some are even purple so look it up lol :)
desert plants and tropical plants have evolved in different ways such as: . desert plants sore water to survive whereas tropical plants have waxy leaves to drain the water . tropical plants have huge leaves to help encourage pollinators and reach the sun light whereas desert plants have thorns and smaller leaves that are grey to reflect the sunlight.
Antarctica. There is a desert drier than Australia which is the Atacama desert in Chile in South America but Antarctica can be much drier than the Atacama desert especially the Mc Murdo Dry Valleys
Cacti have spines that evolved from leaves.
because they have CAM photosynthesis (they absorb CO2 at night), they don't have leaves with large surface area (the spines are leaves) to save water (minimizes transpiration), They photosynthesize through the stem rather than the leaf.
Cacti live in the deserts of the Americas and many have sharp spines. In Africa there are other plants, euphorbias for example, that resemble cacti but have thorns rather than spines.
Yes
No, dandelions do not have spines. They are known for their bright yellow flowers and deeply lobed green leaves, which are typically smooth rather than spiny. The plant has a hollow stem and a taproot, but lacks any spiny structures.
Not necessarily
they have bigger eardrums than us
No, not all cactuses have spines. Some cactus plants have many more than others. Some have longer or shorter, finer or thicker spines. Some have white spines, some colored. And some don't have any spines at all.
Generally, leaves of desert plants are smaller than their counterparts elsewhere. However, their is no particular size unless you specify a particular species of plant
The animals in the desert are better than the animals in the desert because the desert animals can survive like years without water. The animals in the rainforest get water like everyday so the animals in the rainforest would die if they went like a day without water.
prevention is better than cure.
You would have to define "better" in order for us to answer that. Not possible to answer as is. Sorry.
