Rank and justify the importance of the organelles based on what you think?

Every cell in your body contains organelles (structures that have specific functions).  Just like organs in the body, each organelle contributes in its own way to helping the cell function well as a whole. The nucleus, mitochondria and chloroplasts are all organelles. Some organelles are found only in some cell types. They have roles that are important to the specific function of that cell type  Chloroplasts (left) are the site of photosynthesis in plant cells, storage granules  provide a storage site for proteins in secreting cells, and microvilli aid absorption of nutrients during digestion by increasing  the surface area of cells in the intestinal wall, an organelle is a specialized sub unit within a cell that has a specific function.  Individual organelles are separately enclosed within their own lipid bi layers .The name organelle comes from the idea that these structures are parts of cells, as organs are to the body. Organelles are identified by microscopy, and can also be purified by cell fractionation. There are many types of organelles, particularly in eukaryotic cells. While prokaryotes do not possess organelles per see,  some do contain protein-based bacterial micro compartments, which are thought to act as primitive organelles. Microscopic function of an organelle is shown in  the diagram,as an organelles can't be seen by a naked eye.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
