The edges of the olive leaves are whole.
Leaves are a vital part of plant beings. Thanks to them they can breathe and photosynthesize, a process that allows them to feed and grow. What's more, it is usually in them where problems first manifest, so it is highly recommended to observe them daily to detect them as soon as possible and solve them.
Next we will explain how are the edges of the leaves.

The leaves are classified according to their shape, which can be simple when they only have one 'flake', or compound when they have two or more. Most plants have simple leaves, but the truth is that there are others, such as the tree Ausculus hippocastanum (Castaño de Indias) who has chosen to have them composed. Depending on the climate of the place, as well as the type of soil and altitude, plants have developed some leaves or others to adapt to the environment where they are.
In fact, those that live in hot climates with abundant rainfall they usually have larger leaves than those that live in equally hot, but dry regions. An example would be the Alocasia. In the tropical and humid forests of Borneo we find the A. robust, a plant whose leaves measure 3m in diameter; on the other hand, the A. macrorrhiza (better known by its other name: Elephant Ears) is somewhat smaller, 50cm in length, since it lives in regions where the rains are not as frequent as in Borneo.
The edges of the hydrangea leaves are serrine.
To see how the leaves of plants vary in size, I invite you to do the following experiment: acquire two plants of the same species. Give one of them the proper care, but let the other go a little thirsty. After a while, you will see that the one that has not had enough water begins to reduce the size of its leaves. When you decide to give it more water, it will once again have leaf blades the size that corresponds to it.
It's funny, right?
