Problems solved by technology

[0003] However, there are few reports on the structure in the mesophyll of fossil plant leaves formed in geological periods, and they are only scattered in foreign references. In China, there are only reports and studies on Eucommia gum silk, and the description of its experimental methods is relatively simple. The experimental method is also an experimental procedure and method formulated to observe the morphological and structural characteristics of the leaf epidermis of the plant

Embodiment Construction

[0019] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following technical solutions in the present invention are clearly and completely described. Obviously, the described embodiments are some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0020] The content of the present invention is aimed at the remains of well-preserved plant fossil leaves, and provides a method for reliably observing and identifying substances between the upper and lower epidermis of plants. The method specifically includes the following steps:

[0021] 1. Use a smaller blade to take a small amount of epidermis fragments from fossil plant leaf specimens, put them into a clean petri dish, and soak in distilled water for about 1 ...

Abstract

The invention provides a method for observing a morphological structure in mesophyll of a fossil plant. The method adopts means of immersing a fossil in distilled water, 40% hydrofluoric acid, Shu liquid and an alkaline solution successively, thereby removing impurities from the epidermis of the fossil; and then a mesophyll substance is separated independently through a sucker or a pipette for observation and identification. According to the method, the morphological observation and determination on the mesophyll in each experimental procedure are controlled to improve extraction of morphological character and function information of the plant, thereby providing reliable information materials for further identification on fossil plant leaves.

Description

technical field [0001] The invention relates to the technical field of geology, in particular to a method for observing the internal morphological structure of fossil plant mesophyll. Background technique [0002] The mesophyll of modern plants contains a large number of structures and substances, which are of great significance in the identification of plants, such as the camphor extracted by humans, that is, the oil cells from the Lauraceae plant tissues, and the observation of oil cells in modern plants With the help of a microscope or an electron microscope, because the leaves of modern plants come from a wide range of sources, the methods of processing plant leaves are relatively mature, and the method of observation is relatively simple. [0003] However, there are few reports on the structure in the mesophyll of fossil plant leaves formed in geological periods, and they are only scattered in foreign references. In China, there are only reports and studies on Eucommia ...
