What are some examples of plants with thorns and how do they benefit the ecosystem?
Plants like roses, blackberries, and cacti have thorns that protect them from animals and help them survive. Thorns also provide shelter for small animals and birds, and can act as a deterrent to prevent herbivores from eating the plants. This helps maintain the balance of the ecosystem by protecting plant species and providing habitats for other organisms.
What is the rose special structures for adaptation and survival?
Roses have thorns to deter herbivores from eating them and to protect the plant from damage. Their petals are brightly colored to attract pollinators for reproduction. Additionally, roses have a strong fragrance to attract specific pollinators like bees.
Why does a rose plant have thorns?
No, not on the roses but on their pinesues. So that nothing can eat them. It is a defense mechanism. If an animal bites into a rose, and gets a mouthful of thorns, they won't want to eat it anymore.
Did rose plants always had thorns?
No. Nature provides exceptions to every rule. Some truly thornless roses do exist and a greater number of "nearly thornless" roses are available. Some roses, such as Polyanthas, tend to have fewer thorns as a species. As a point of proper nomenclature, roses don't have thorns, they have prickles.As to the evolution of these protective mechanisms, the rose prickles are similar to plant hairs and are are extensions of the cortex and epidermis. They evolved to protect the plants when they grew in poor soils and could not regenerate rapidly when gnawed on my browsing animals.Some "thornless" varieties include:Bleu Magenta (Hybrid Multiflora, mauve)Chloris (Alba, light pink, very fragrant)Goldfinch (Hybrid Multiflora, light yellow/white, fragrant)Hippolyte (Gallica, mauve/red blend)Kathleen Harrop (Bourbon, light pink, fragrant)Lady Banks Rose (Species, white or yellow)Lykkefund (Large-flowered Climber, white/light yellow)Mme. Legras de St. Germain (Alba, white, fragrant)Mme. Plantier (Alba, white, fragrant)Tausendschön (Hybrid Multiflora, pink blend)Veilchenblau (Hybrid Multiflora, mauve, fragrant)Zéphirine Drouhin (Bourbon, medium pink, fragrant)
Why are some thorns softer than others?
Thorns can vary in hardness due to differences in their structure, composition, and the plants they come from. Some thorns may have a higher water content or be less densely packed, making them softer to the touch compared to thorns that are more rigid and densely structured. Additionally, the evolutionary purpose of the thorn can influence its hardness, with some evolved to be more pliable for defensive purposes while others are hard and sharp for protection.

Do you complain because roses have thorns or rejoice because thorns have roses?
Not all thorns have roses (example: briar bushes) and just because a rose bush has thorns does not mean it has roses. So the premise of this is illogical. You cannot depend on thorns to assume you'll find or see roses, that roses will ever be found or seen, or whether you're looking at a rose bush at all. The only logical answer, then, is to rejoice that we have gloves to hold a rose stem and snippers to cut off its thorns if present. But we also must appreciate that thorns serve a protective function for the roses we enjoy. For example, a deer's nose is awfully sensitive--when it comes to nosh (eat) a rosebud, its nose will get pricked by thorns so it learns to leave roses alone.
Are a roses thorns inherited or behavioral?

Why do some roses have many thorns and some hardly any?
