From cells to tissues to organs to organ systems to the organism itself. That is the hierarchy of cytology to most eukaryotic organisms. Cell is the basic unit of every living organism. This basic unit has specialization that functions differently for each pattern of structural and functional processes.
Enzymes catalyze chemical reactions involving the substrate (s).
PALISADE CELLS ARE CELLS FOUND WITHIN THE MESOPHYLL IN LEAVES OF DICOTYLED ON PLANTS.THEY CONTAIN CHLLORPLASTS,WHICH CONVERT THE ENERGY STORED IN PHOTONS TO CHEMICAL ENERGY THROUGH PHOTOSYNTHESSIS,WHICH IS MADE UP OF TWO MIN STAGES;THE LIGHT DEPENDENT REACTIONS AND LIGHT INDEPENT REACTIONS
If a person is shot, and the bullet destroys the part of the brain called the medulla, which maintains basic life functions (heart rate, breathing), there is virtually no chance for surviving that injury
