Let me ask you a little question: do you know why the egg is oval and the fruit is round?
It's really interesting to look at this question. These problems can be seen everywhere in life, but it's not easy to be able to tell the truth. Let's listen to the analysis of developing agriculture through science for you.
Now that we are talking about circle and oval, let's first understand the difference between the two. For the same perimeter, the area of a circle is larger than that of an ellipse.
And the same is true for volume! In other words, in the case of producing a certain amount of eggshell in the hen, if the egg is oval, it will save a little more volume and space, and the hen can store more eggs.
In addition, the force that the circle can bear is also greater under the same circumstances. Here is a short story. There was once a Hercules. People said that although you were strong, you could not break a small egg. Hercules doesn't believe it, so he tries, but no matter how hard he tries, he won't break.
Because of the curved structure of the egg. The arc structure evenly distributes the force on the whole egg, and the overall force on the egg is uniform, that is, the force exerted by your left hand on the egg is partially offset by the strength of your right hand, so it is not easily broken.
It is precisely because of this relationship that eggs are not easy to break during production and are not easy to roll and break after they fall to the ground.
However, apples can not be explained in this way, the expansion of fruit (apple) is through the stalk to deliver nutrients to the apple, this nutrient solution is liquid.
You should have seen the syringe inject liquid, when pushing the liquid out, if the push is relatively small, take a closer look at what the droplets look like before they fall. It's round, right? Yes, it is round, but the difference is that the droplet falls when it is too large. But for fruit, due to the adhesion of plant tissue and intercellular structure, it does not appear as scattered as liquid droplets, but appears round like the surface tension of water droplets.
