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
Experiments for the observation of protoplasmic movement
Within living cells, the phenomenon of active movement of protoplasm is collectively known as protoplasmic movement. Protoplasmic movement is one of the importa
Chlorophyll saponification assay
Chlorophyll is an ester of a dicarboxylic acid that saponifies with a base to form a basic salt of chlorophyllic acid; after the formation of the salt, chloroph
Protoplasm isoelectric point measurement experiment
Protoplasm's main constituent -- protein for amphoteric compounds, it is in different pH medium, its dissociation is different: when the medium's pH value is mo
Experiments for the quantitative determination of chlorophyll
According to the absorption spectrum of chlorophyll on visible light, the use of spectrophotometer at a particular wavelength to determine its optical density,
Experiments on the absorption spectra of chlorophyll and carotenoids
Because chlorophyll and carotenoids have different molecular structures, they have different absorption spectra. Carotenoids absorb blue-violet light and chloro
Experiments on the determination of photosynthetic intensity of plants
According to the similarity of the structure and physiological function of the two sides of the leaf midvein, you can first cut off half of the leaf in the dark
Experiments on oxidation and phosphorylation in isolated mitochondria
When sufficient oxygen is supplied to plant tissues, plant cells can oxidize substrates completely. When glucose is fully oxidized as a respiratory substrate, C
