Observations on the basic structure and posterior contents of plant cells
Cells are the basic units that make up living organisms. Compared with animal cells, plant cells have their own special cell components, such as cell wall and p
Determination of plant alkaloid content
Alkaloids are natural nitrogen-containing organic compounds, but do not include amino acids, proteins, nucleic acids, chlorophyll, choline, methylamine and othe
Fluorescent labeling and observation of plant organelles
Plant cells contain abundant organelles, including vesicles, plastids, mitochondria, Golgi apparatus, ribosomes, endoplasmic reticulum, microtubules and microfi
TUNEL assay for programmed cell death in plants
Programmed cell death (PCD) is a genetically regulated process that actively removes excess, injured cells during plant growth and development or in response to
Directional growth of plant pollen tubes to ovules
Since the sperm cells of angiosperms are unable to move, the completion of sexual reproduction in angiosperms requires the use of pollen tubes to deliver the sp
Plant chromosome karyotyping
Various organisms in nature have relative stability in the form, structure and number of their chromosomes. The complete set of chromosomes contained in the gam
In vivo observation of the microfilament skeleton of plant cells
In a broad sense, the cytoskeleton is a type of organelle that contains three different components: microtubules, microfilaments, and intermediate fibers. So fa
Observations on pollen germination and pollen tube growth in vitro
After landing on the stigma, pollen, the male gametophyte of plants, grows pollen tubes through germination and transports sperm cells to the embryo sac to comp
