|
Ribosomes |
These are the sites of protein synthesis |
|
|
Vacuole |
These are membranous storage bags with no inner structure. They usually store watery liquids |
|
|
Nucleolus |
These assemble ribosomes |
|
|
Lysosome |
These are tough membranous bags filled with digestive enzymes. They function in intracellular digestionin protozoans and white blood cells. They also break down faulty and old cellular organelles |
|
|
Cilia and Flagella |
These are projections found in small numbers in many protists and the sperms of animals. They are also found in bacteria and their function is to move the cell around. |
|
|
Golgi Bodies |
The manufacturing warehouse of the cell, it is involved in sorting, modifying and shipping. |
|
|
Rough Endoplasmic Reticulum |
This is a system of membranous sacs and tubules and is responsible fr the modification of proteins. It has a rough appearance due to the presence of a coating of ribosomes, which are the site of protein synthesis. |
|
|
Centrioles |
These form the spindle and asters during animal cell division. |
|
|
Chloroplasts |
This is found only in the cells of green plants. It is the site of photosynthesis. |
|
|
Mitochondria |
This is the cell's power plant. It is the site of the Kreb's Cycle and the Respiratory Chain in aerobic respiration. |
|
|
Nucleus |
This controls the cell and carries the genetic code. It contains the nucleolus. |
|
|
Smooth Endoplasmic Reticulum |
This produces steroids; plays an important role in calcium storage in muscle cells and affects muscle contraction; has functions in fat metabolism and detoxifies poisons and drugs. This has a smooth outer surface. |
|
|
Plasma Membrane |
This surrounds the cell and keeps it seperate from the outside medium. It is selectively permeable, in other words it lets some substances pass through it and not others. It receives information about changes in its surroundings and responds to these changes. |
|
|
Peroxisome |
These are membrane-bound bodies which lie close to the mitochondria or chloroplasts. They remove hydrogen from certain reactions to form hydrogen peroxide. |
