Khalan A. AP Biology Plants Immune Systems Plants serve as the main source of nutrients for countless organisms such as fungi‚ protists‚ vertebrates‚ and insects. In comparison to humans‚ a plant’s “immune system” is insignificant. However‚ plants have adapted and evolved chemical‚ physical‚ and protein based mechanisms to protect themselves against invaders. A plant’s first line of defense against pathogens is their innate immunity. The “innate-immune system” is a non-specific immune

Title: Virus Module: Biochemical Processes______ All viruses are pathogens. Some viruses are deadly‚ for example‚ HIV and Ebola virus. Unlike bacteria‚ fungi and protists‚ viruses do not fit into the framework of cellular organization that is the hallmark of organisms. Bacteria‚ fungi and protists are cells but not virus. Viruses have unique structural and functional properties and cannot reproduce unless they are inside the cell. In fact‚ they can neither generate energy nor make proteins

viewed with the aid of a microscope or electron microscope. The importance of microbiology includes: used in biomedical research‚ creation of medicines‚ environmental applications and new research tools. Disease causing organisms include: protists‚ bacteria‚ viruses and other microorganisms. Bacteria are important for fixing N2 in a usable form for plants. Bacteria and some fungi are important in decomposition and recycling of raw materials. Industry applications of microbiology:

Evolution as a theory * Theory- in science‚ a well substantiated explanation of some aspect of the natural world Evolution- the accumulation of inherited genetic changes within populations over generations * Does not refer to changes that occur in an individual within its lifetime * Not limited to speciation that may only occur over long periods of time * Can occur over a few generations‚ and is most commonly expressed as an adaptation to a changing environment or the change in allele

Bacteria and Archaea The Archaea are presently recognized as one of the two main domains of prokaryotes. The majority of genes that indicate Archaea to be different from Bacteria are for information transfer processes such as DNA replication‚ transcription and translation. Of these‚ DNA replication machinery appears to be most different between the two domains. In terms of transcription‚ the core subunits of the RNA polymerase are the same in Bacteria and Archaea‚ but archaea also contains several

Cnidarians Cnidaria is a phylum containing some 11‚000 species of simple animals found exclusively in aquatic‚ mostly marine‚ environments. Cnidarians get their name from cnidocytes‚ which are special cells that carry stinging organelles. The corals‚ which are important reefbuilders‚ belong here‚ as do the sea anemones‚ jellyfish‚ sea pens‚ sea pansies and sea wasps. The names Coelenterata and Coelentera were once applied to the group‚ but those names included the Ctenophores‚comb jellies
