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.
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.
Before being roasted, sunflower seeds are living. They contain an embryonic plant on the inside.
A flowering plant with two cotyledons in their seeds is called a dicot plant. Dicotyledonous plants have seeds that typically produce two embryonic leaves upon germination, compared to monocot plants that have only one cotyledon. Examples of dicot plants include roses, sunflowers, and beans.
a non flowering plant is a plant which do not bear flowers whereas a flowering plant is a plant which bears flowers
Yes, roses have pistils. The pistil is the female reproductive organ of the flower and is typically located in the center of the bloom.
Both roses and ferns are used as ornamental plants. Rose cut flowers and fern leaves are used in decoration. Rose is an angiosperm and ferns are pteridophytes.

No. Most flowering plants only flower at certain seasons, and for some crops (cabbages, for example) the plants are harvested before they flower.
The ocotillo plant is a common desert plant found in the southwestern United States and Mexico that has thorns but is without leaves. It is known for its long, vertical stems covered in sharp spines, which help reduce water loss and protect the plant from herbivores. The plant produces leaves only after a rainfall to maximize its photosynthetic potential.
Many roses only flower once or twice in a season and are not repeat flowering. If the rose is not flowering over a very long time, the soil may be too rich in nitrogen, and not high enough in the other needed elements. Garden centers have products that will promote flowering, or try ash around the plant. The other possibility is that the plant is now more shaded than before, as roses need full sun to flower well.
Flowering plants (Angiosperm and gymnosperms) are found on almost every continent of the world. The only exception is Antarctica, where only limited plant life is found
