How to make hollow leaves

To make hollow leaves:

Cook the leaves with a dilute solution of sodium hydroxide for a few minutes, then gently brush off the mesophyll with a brush. Use older leaves, otherwise It is easy to brush out the leaf veins.

Leaves

are the vegetative organs of higher plants. They develop laterally from the leaf primordia of the plant's stem. Leaves contain chloroplasts, which are the main organs for photosynthesis in plants. At the same time, the transpiration of plants is also achieved through the stomata of leaves. Leaves can come in a variety of shapes, sizes, colors, and textures.

Leaves only appear on true stems, that is, only vascular plants have leaves. All higher plants such as ferns, gymnosperms and angiosperms have leaves. In contrast, bryophytes, algae, fungi, and lichens do not have leaves. In these flat bodies (Thallus) only structures similar to leaves can be found, but only as analogues (Analoga).

Leaves can come in a variety of shapes, sizes, colors, and textures. Leaves can be gathered in clusters or scattered all over the place. The edges of the leaves can be smooth or serrated.

A complete leaf consists of the following three parts: Most of the leaves are broad and flat, suitable for receiving sunlight. The petiole supports the leaf and connects the leaf to the stem. The stipules protect the young leaves. (Some plants do not have stipules, and some plants have stipules that fall off very early.
