Summary. Like all living organisms, plants use deoxyribonucleic acid (DNA) as their genetic material. The DNA in plant cells is found inthe nucleus, the mitochondria and the chloroplasts. The latter two organelles are descendants of bacteria that were captured by a eukaryotic cell and have become...

Define genetic material Are meristems cells diploid? An aster forms during this stage of meiosis. What type of alleles will a pure plant have? How does a strawberry plant reproduce? What was Mendel trying to determine? Where does meiosis occur in flowering plants?
Various natural compounds, ranging from cell wall components to metabolic enzymes have been reported to protect plants from infection by pathogens and hence provide specific resistance to hosts against pathogens, termed as induced resistance. It involves various biochemical components, that play an ...
