why some of them smell? what's the reason?

excerpt from http://www.millsfarmplants.co.uk/Scented_plants.htmScent in flowers is most usually produced in the petals. On the petals’ surface is a layer of cells, called epidermal cells. In these cells various types of fragrant oil are made, commonly known as 'essential oils'. The scent of each flower is chemically quite complex: for example, the clove scent of pinks is made up of about 60 different chemicals.
Flowers have a scent as a way to attract pollinators, such as bees and butterflies. The scent acts as a signal to these insects that the flower contains nectar, which they can collect and use as a food source. This helps the flower to reproduce and continue its species.
The scent of a flower is determined by its specific chemicals, also known as volatile organic compounds (VOCs). Different flowers have different combinations and concentrations of these compounds, resulting in unique scents. Factors such as genetics, environment, and pollinators can also influence the scent of a flower.
No, not all flowers have a scent. Some flowers rely on their vibrant colors or unique shapes to attract pollinators, while others may have a very subtle or unnoticeable scent. Additionally, some flowers have evolved to produce scents only at specific times, such as at night when their pollinators are most active.
Yes, the scent of a flower can change. This can be due to various factors such as aging, environmental conditions, or pollinators. As a flower ages, its scent may become more intense or change in composition. Environmental factors such as temperature and humidity can also affect the scent of a flower. Lastly, different pollinators may have different preferences for certain scents, thus influencing the flower's scent over time.
While the primary purpose of a flower's scent is to attract pollinators, the pleasant scents of flowers can also have a positive effect on humans. Studies have shown that certain flower scents can improve mood, reduce stress, and even have therapeutic effects. This is why flowers are often used in aromatherapy and other relaxation practices.
