why do plants flower at different times of the year
The Rocky Mountains are home to more than 3,000 different kinds of wildflowers. Flowers bloom at different times throughout the year, some of which begin blooming in the early spring as the snow melts and others wait till later in the year. Why do they do that? Why don t they all just bloom at the same time? When looking at the natural world, most things come down to a simple quest for survival. Many of the explanations for behavior can be answered by understanding what will help give the plant or animal the best chance of surviving and reproducing. Wildflowers are an excellent example of this. Flowers bloom at different times of the year in order to give them the best chance of getting pollinated, after which they will produce a seed and a new plant. Imagine what would happen if all the flowers in the mountains bloomed at the same time. PThe mountains would probably look absolutely beautiful for that short period of time. But, the bees or other pollinators would be busier than they already are. They simply would not be able to pollinate all of the flowers, which means many flowers would not produce seeds.
PIf a plant does not make seeds, then it will not reproduce. POver time,Pthere may not be as many different kinds of flowers in the mountains since some of them would die. Here is a super short explanation of a complicated topic flowers bloom at different times of the year in order to give themselves the best chance at getting pollinated and reproducing. An Arrowleaf Balsamroot is a beautiful yellow flower that is an early spring bloomer common in lower elevations.
Can you imagine if were like human beings? Envision a bush. One day, a yellow blooms. A few days later, a pink blooms. A couple of weeks later, several red roses together. Rather than doing their own thing and seeking their own time in the spotlight, however, real bushes all one color with all the flowers appearing at about the same time. It's a glorious sight, and we humans are delighted when we see it. Those bushes don't at the same time as the lilies and the daffodils, though. Beginning in springtime each year, flowers begin to, with different plants blooming at different times month after month.
But exactly how do plants know when to? It's a mystery that has puzzled scientists for centuries. As far back as the 1930s, scientists knew that plants somehow sensed the length of days to know when springtime was approaching. Russian scientists suspected that a mysterious substance (a mystery they called Бflorigen") was sent through the leaves to the tips of shoots to stimulate buds to form. Today, scientists have conducted advanced studies that they believe might finally explain how plants know when to. For example, scientists now know that plants have an internal circadian clock that helps them know when is increasing and days are getting longer. They believe this internal clock works because of proteins that work as photoreceptors activated by. Different plants thrive at different times of the year, since they each have individualized needs for, precipitation, and other important factors. This is why not all plants on the first day of spring. Instead, they at the times when they will have the best chance to survive and thrive.
When those proteins tell the that it's time to, the sets in motion a that will result in flowers blooming. Specifically, the plants begin to produce a called Flowering Locus T in their leaves. The then travels to the tips of shoots, where it undergoes changes that spur cells to begin to form flowers. Scientists now believe that Flowering Locus T is the elusive Бflorigen" Russian scientists speculated about almost 100 years ago. Why would scientists care so much about how plants know when to? It's more than just intellectual curiosity. Some scientists believe that understanding these will allow them to regulate the timing of flowering of plants grown as, such as, wheat, and barley. For example, usually flowers late in the year. If scientists could the flowering to create an early-flowering variety of, it could be possible in some areas to produce more than one per year. Other experts speculate that such manipulations could also lead to higher yields of plants grown for biofuels.
