All plants develope ways of surviving the extremes. The thick, waxy leaves of poison ivy slow transpiration or loss of water during dry,hot times.
Hope you don't get it.
Webbed feet, slimy body thick fur leathery skin
Fleshy leaves and thick surface layers help in keeping water inside the plant, preventing it from drying out. The cactus is an extreme example of this adaptation, made to survive in arid environments.
The leaves of water hyacinth are long and leathery and have wax coating surrounding them. They are made up of long spongy parenchyma tissues that have several air pockets. The air pockets help the leaves to stand erect and float on the surface of water. Arsha 9th
Cacti have a thick stem so that when water/nutrients are available they can be absorbed in mass amounts for storage for use for a long period of time
The prodigy have sung poison if that's any help

They store water in a little trunk. (Kind of like a cactus.)
Camels do eat tumbleweeds. Aside from this, they also feed on grass, leaves, and plants. Their thick lips help them in eating hard and thorny plants in the desert.
organic matter and humus are related because they are darker in a way. and many leaves that fall from forest trees every autumn help form humus. the decaying leaves and plentiful rainfall form thick fertile soil.
Very thick, 3-5 feet thick.
Poison is created by mixing two chemicals that create a poison. This link might help http://irowiki.org/wiki/Create_Deadly_Poison
The cactus modified leaves to sreate its spines, which are used for protection and storage of water. Carniverous plants have the "mouths," which are modified to help the plant obtain its needed nitrogen. Coniferous trees created needles instead of leaves. These needles are used for water storage and photosynthesis, and they have a very thick cuticle.
