- Essay of Eukaryotic Organelles 10/1/96

- The mitochondria has an eggshape structure. The mitochondria consists of
- an inner and outer membrane. The outer membrane is what shapes the
- organelle to its egglike shape. The inner membrane which folds inward
- makes a set of "shelves" or cristae that allow the reactions of the
- mitochondria to take place. The more the mitochondria makes these reactions
- the more the inner membrane folds. This happens because the mitochondria
- now has more surface area connecting it to its surroundings. The processes
- that the mitochondria make are to break down the high energy organic
- molecules into smaller more useful packages.
- The endoplasmic reticulum is a network of tubes and channels that
- transport and with the help of ribosomes produce proteins. The rough
- endoplasmic reticulum contains ribosomes which are not present in the
- smooth endoplasmic reticulum. The rough endoplasmic reticulum allows the
- cell to produce proteins. The smooth endoplasmic reticulum is used in the
- detoxification processes in the cell and the transitional endoplasmic
- reticulum is used to breakdown glycogen to glucose. The endoplasmic
- reticulum is versatile and grows and shrinks according to the cell's
- activities.
- Chloroplasts which are found in plant cells are used in the process of
- photosynthesis. They fall into the category of plastids but they are
- differentiated in that they contain chlorophyll. These organelles produce
- chemical reactions from the energy that the sun gives them.
- The Golgi complex's structure is made up of many flattened membranes sacs
- that are surrounded by tubules or vesicles. These are called the
- cisternae. The golgi complex accepts vesicles from the endoplasmic
- reticulum and modifies them for usage in the cell. The golgi complex is
- used to distribute materials which help form the cell membranes. They also
- assemble the membranous material by producing glycolipids and
- glycoproteins. The golgi complexes also hand their vesicles materials for
- secretion. The golgi complex could not do its job without the help of
- vesicles. Vesicles bring and send the organelle its materials.
