Experiments for the determination of photosynthetic intensity
Modified half-leaf method is part of the plant symmetrical leaf shade or remove placed in the dark, the other part is left in the light for photosynthesis, afte
Experiments on the extraction, isolation, properties and quantitative determination of chloroplast pigments
Chloroplast pigment is an important substance for plants to absorb sunlight energy for photosynthesis. This experiment is to learn the extraction and separation
Experiments for the determination of transpiration intensity by weighing and felling
When a branch with leaves is inserted in a burette filled with water, the leaves are still constantly undergoing transpiration. The strength of transpiration va
Experiments for the determination of respiratory strength
Respiration intensity is one of the most important indicators of plant life activity and is necessary to be measured in plant physiological research and product
Experiments to determine the degree of water deficit in plants
The proline content in plants increases when they are dehydrated. The proline content in plants reflects the water situation in plants to a certain extent, and
Experimental morphological observations on vesicles in young wheat roots
The tip of the germinating wheat embryonic root was cut (about 1 cm from the tip) and immersed in neutral red solution for live staining for 10-15 min, then rem
Catalase activity assay experiment
H2O2 is strongly absorbed at 240 nm, and catalase decomposes hydrogen peroxide, causing the absorbance of the reaction solution (A240) to decrease with reaction
Experiments on the separation of liquid bubbles
Tear the epidermis of purple onion or radish leaves, put it on a slide, add a little drop of water and then cover the coverslip, observe the cells in the prepar
