There would be far less food on planet earth since plants must flower before they produce fruit. This is not an opinion. It is a fact.


Food for both man and animals results from intricate cycles—including the water cycle, the carbon cycle, the phosphorus cycle, and the nitrogen cycle. It is general knowledge that in the vital process of photosynthesis, plants use carbon dioxide and water as raw materials to produce sugars, using sunlight as the energy source. Incidentally, during photosynthesis plants release oxygen. Could this be termed a “waste product”? To us this by-product is hardly waste. It is absolutely essential that we breathe in oxygen and use it to metabolize, or burn, food in our body. We exhale the resulting carbon dioxide, which plants recycle as a raw material for photosynthesis. We may have studied this process in a basic science class, but it is no less vital and marvelous. And this is just the start.
In our body cells and in those of animals, phosphorus is vital for transferring energy. From where do we get our phosphorus? Again, from plants. They absorb inorganic phosphates from the soil and convert them into organic phosphates. We consume plants containing phosphorus in these forms and use it for vital activities. Thereafter, the phosphorus returns to the soil in the form of body “wastes” that can again be absorbed by plants.
We also need nitrogen, which is part of every protein and DNA molecule in our body. Although about 78 percent of the air around us is nitrogen, neither plants nor animals can absorb it directly. So nitrogen in the air must be converted into other forms before it can be taken in by plants and later utilized by humans and animals. How does that conversion, or fixation, occur? In various ways. One way is by the action of lightning. Nitrogen fixation is also accomplished by bacteria that live in nodules on the roots of legumes, such as peas, soybeans, and alfalfa.

Since plants make oxygen, if the flowers were gone there would be a significant shortage of oxygen.
Also, I think that flowers are beautiful and without them it would be sad and a less beautiful world.

Trying to get your homework done?

If flowers did not exist we would have a shortage in oxygen and might die.
