It's the thorns on cactus plants and roses that make them both difficult to hold. On both plants, the thorns serve to defend and protect the stem and the flower. But on the cactus, the thorn is a modified leaf. On a rose, the stem has both thorns and regular leaves.
no it is a mammle those thorns are really hairs
They vary in size from species to species and my be the size of nails or like small hairs.
The thorns on cacti are like seeds, if you want to reproduce a cactus you will probably need a green house, if you don't have a greenhouse you can take a plastic bag and poke small holes in it and drape it over the cactus. Cactus thorns are sharp and prickly they are a natural defence system.
