BJ Organelles
Question | Answer |
---|---|
"command central" of the cell because it contains almost all of the cell's DNA . dense bodies called nucleoli, which contain ribosomal RNA Commonly seen within | Nucleus |
the machines that coordinate protein synthesis, or translation. read the messenger RNA copy of the DNA and assemble the appropriate amino acids into protein chains. | Ribosomes |
powerhouses of the cell. double-membrane-bound organelles that are the site of respiration | Mitochondria |
network of tube-like membranes continuous with the nuclear envelope that comes in rough (with ribosomes) and smooth (without ribosomes) varieties. | Endoplasmic Reticulum (ER) |
The stack of flattened, folded membranes that acts as the "post office of the cell." Here proteins from the ribosomes are stored, chemically modified, "addressed" with carbohydrate tags, and packaged in vesicles for delivery. | Golgi Apparatus |
membrane-bound organelles that contain digestive enzymes that break down proteins, lipids, carbohydrates, and nucleic acids. They are important in processing the contents of vesicles taken in from outside the cell | Lysosomes |
Found only in plants and certain protists, contains the green pigment chlorophyll and is the site of photosynthesis | Chloroplasts |
Found mainly in plants and protists, liquid-filled cavities enclosed by a single membrane. They serve as storage bins for food and waste products. | Vacuoles |
