Cell Organelles1
and their functions
Question | Answer |
---|---|
Endoplasmic Reticulum | interconnected membranes with spaces between them forming canals; has openings to the outside of the call and is connected to certain other organelles and to the nuclear membrane |
Ribosomes | responsible for the synthesis of protein molecules |
Golgi Apparatus | responsible for the synthesis of carbohydrate molecules for export from the cell |
Mitochondria | energy source of the cell, ATP synthesis. "Powerhouse of the cell". Present in great numbers in muscle tissue |
Lysosomes | capable of breaking down and digesting molecules of protein and carbohydrates when their enzymes are released. White blood cells have a great number of lysosomes |
Centrioles | help form spindles that appear during mitosis (cell division) |
Cell Nucleus | directs activities of the cell; contains relatively large quantities of DNA |
Microvilli | tiny hair like projections of the cytoplasmic membrane located only in the small intestine to facilitate absorption by increasing surface area |
Cilia | small hair like projections of the cytoplasmic membrane located in the respiratory system acting to propel mucous upward |
Flagella | a single projection, such as found on a sperm cell allowing for propulsion of that cell |
