Document Summary

All eukaryotic cells are fundamentally similar to one another (very different from prokaryotes) . Nucleus is biggest difference between prokaryotes and eukaryotes . Cell is wrapped in membrane made of phospholipids & proteins . Each organelle is bounded by a membrane made of lipids and proteins (suit its function) . 4 basic functional groups of organelles : nucleus and ribosomes carry out genetic control of the cell, organelles involves in manufacture, distribution, breakdown of molecules reticulum, golgi apparatus, lysosomes, vacuoles, Endoplasmic peroxisomes : mitochondria (all cells) & chloroplasts (plant cells) are involved in energy processing, structural support, movement, communication between cells. Internal membrane of eukaryotic cell partitions it into compartments . Cellular metabolism = chemical activity of cells, occurs within organelles . Many enzymatic proteins built into membranes of organelles . Chemical conditions maintained in fluid-filled spaces within organelles . Almost all organelles and other structures of animal cells are also present in plant cells .

One effective learning strategy when trying to learn largeamounts of factual information is to group items, or âchunkâ. Youshould include all important structures of the cell (this includescell membrane and membrane adaptations as well as organelles).Examples of general categories could be location, function,morphology, etc. Your categorization groups must tell the viewersomething about the structures. Once your structures are groupedaccording to the characteristics they share, you should include ashort phrase about what differentiates them from each other withinthe group. Citation of your source material must be present.

List of Organelles:

Nucleus, Nuclear envelope/membrane, Nucleolus, Ribosomes,Endoplasmic reticulum, Golgi apparatus, Mitochondria, Plasmamembrane, Cytoskeleton, Transport/secretory vesicles,Phagosomes/endosomes-including sorting & recycling endosomes,Lysosomes, Peroxisomes, Lipid droplets, Glycogen granules

I started this assignment and was going to go withfunction and morphology. Below is what I have so far, but I'mhaving a difficult time coming up with a short phrase for each anddistinguishing between the organelles that can change shape/morphand those that cannot. I am open to changing the categories that Ihave chosen to chunk. I've never used this technique before so it'sa new concept for me.

Function

Protein Synthesis â Nucleus, Nuclear envelope, Nuclear porecomplex, Ribosomes, Rough endoplasmic reticulum, Golgi apparatus,Plasma membrane

Energy Production â Mitochondria, Lipid droplets, Glycogengranules

Transportation â Transport vesicles, Phagosomes,Cytoskeleton

Metabolism â Lysosomes aid in digestion, Peroxisomes oxidizefatty acids

Morphology

Ability to change shape â Mitochondria, Cell membrane, Nuclearenvelope,

Inability to change shape â Nucleus, Nuclear envelope,
