Methods of studying plant growth [analysis, observation]

The most common methods of studying plant growth are as follows.

The plant growth is observed by measuring the length with a ruler that has divisions.

Apply ink marks at a certain distance from each other and then measure the distance between the marks after a certain period of time. If you put these labels on the tip of the root, then after 24 or 48 hours, you can see that the marks at the tip are not stretched, at a certain distance from the root tip — strongly stretched, and in the next zone stretched a little. Thus, we can gain a clear idea of ​​the large growth curve. If you apply the label to the growing onion leaves, you can see the stretching of labels at the bottom, as the leaves of the plants grow at its base. Taken from http://worldofschool.org

You can use the microscope to study the horizontal growth. In this method, the microscope directs at the end of the growing organ, and then using an ocular micrometer counts traversed distance by this organ. Knowing the magnification of a microscope, we can calculate absolute increase of the growing organ over a certain period of time.
