WELL. When it rains, a lot of chemicals and acids come down also.
The thick waxy layer prevents the chemicals from the rain from reaching and destroying the leaf itself.
I beg to differ. Acid rain is caused mostly by human pollution of the environment. The waxy coating on cacti, which doesn't have leaves by the way, is an evolutionary adaption that has existed for many centuries before the industrial revolution. It prevents water loss, also called transpiration, which is extremely high in the desert. Large trees can lose hundreds upon thousands of gallons of water a year to transpiration. The waxy coating 'traps' the water in the plant. Cacti are remarkably adept at holding onto water, which explains their dominance amongst plants in desert climates.
What else can I help you with?
What is the reason that plant cells have an extra thick outer covering andwhatis the outer covering called?
Plant cells have an extra thick outer covering called a cell wall, which provides structural support to the cell and protects it from mechanical damage. The cell wall is made up of cellulose fibers, which give it strength and rigidity.
How does an old man cactus survive?
The old man cactus survives by storing water in its thick, woody stem to withstand periods of drought. Its dense covering of white hair-like spines reflects sunlight and reduces water loss through transpiration. Additionally, the cactus has adapted to survive in dry conditions by having a slow growth rate and low water requirements.
What does cacti mean?
"Cacti" is the plural form of "cactus," which refers to a type of plant known for its thick, fleshy stems and spines. Cacti are adapted to arid environments and are able to store water in their stems to survive in dry conditions.
How does the cactus produce food if the leaves are no longer able to do photosynthesis?
Cacti produce food through photosynthesis in their green stems, not their leaves. In cacti, the stems have chlorophyll and are adapted to conduct photosynthesis, allowing the plant to create its own food. This adaptation helps cacti survive in arid environments where water loss is a concern.
Is it true that The stem of the cactus is too thick to hold water?
No, actually the stem of a cactus is adapted to store water. The thick stem allows cacti to survive in dry desert climates by storing water for extended periods of time.
Why does a cactus need a thick covering?
Because the thick waxy bark prevents the loss of moisture so it stops the plant dying of thirst
Is the covering of a cactus thick or thin why?

What is the thick covering for on a cactus?
To keep it warm at night because its COLD in the desert!.
Why are leaves modified to form spines in the cactus plant how then does the cactus plant make food?
The cactus adapted to its harsh environment by developing thick skin to slow the evaporation of water. The leaves changed in order to reduce the surface area that water could evaporate from and over time became defensive spines to protect itself from animals trying to get inside its thick skin for the moisture. The cactus makes its food, by having chlorophyll throughout the rest of plant. That is why the entire cactus is green.
What is the reason that plant cells have an extra thick outer covering andwhatis the outer covering called?
Plant cells have an extra thick outer covering called a cell wall, which provides structural support to the cell and protects it from mechanical damage. The cell wall is made up of cellulose fibers, which give it strength and rigidity.
Where would a plant with smooth thick skin and a gel filled interior grow?
In the desert (e.g. cactus plants).
Is it better for a cactus cover to be thick or thin?
Thick
What does the word cactus mean?
A desert plant that is characterized by spikes and liquids inside of it.

Why does a cactus plant have fleshly leaf like photosynthetic branches?
Cactus plants have thick fleshly stems.They look like thick leaves but instead they are modified stems.They can store water for long dry weather.Their green colour shows the presence of chlorophyll,an essential input for photosynthesis.
How does a cactus help you survive in a desert?
Cactuses are thrifty plants that live in dry regions. They may not get much moisture where they live, but they manage to make the most of what they do get. Since the cactus's long roots lie close to the surface of the ground, they can catch water from desert rains. And since the roots have a cork-like bark covering them, they can absorb the water quickly. Because the cactus has no leaves, its stems do the job of manufacturing food for the plant and of storing its water. And because these stems grow upward rather than out, not too much of the plant faces the direct drying rays of the sun. These broad stems have a great deal of room for storing the water and a thick covering for protecting it. In addition, the plant's sharp, pointed needles keep desert animals from sucking out this valuable liquid. However, cactus plants have saved the lives of thirsty people stranded in the desert. A cactus plant only three feet tall may have roots spreading out to a length of ten feet across the desert!
