This stratification ensures that both the plankton and the organic carbon are exposed to sunlight throughout the day. According to the biologists the plankton can withstand this large dose of sunlight....Researchers discover mechanism of plant resistance to pathogens

If a pathogen is able to penetrate this physical barrier, for example through a wound, the pathogen will usually be detected by receptors on the surface or inside of the plant cells.
