organelle

  • Cell Membrane: A double layer that supports and protects the cell. Allows materials in and out.
  • Lysosome: Contains digestive enzymes that destroy damaged organelles and invaders.
  • Cytoplasm: Jelly-like fluid that surrounds and protects the organelles.
  • Nucleus: The control center of the cell. Contains DNA.
  • Nuclear Membrane: The membrane that surrounds the nucleus.
  • Nucleolus: A round structure in the nucleus that makes ribosomes.
  • Vacuole: A space surrounded by a membrane that contains fluid.
  • Golgi Body: Processes and packages materials for the cell.
  • Mitochondria: Powerhouse of the cell. Breaks down food to produce energy in the form of ATP.
  • Rough E.R.: Builds and transports substances through the cell. Has ribosomes on it.
  • Smooth E.R.: Builds and transports substances through the cell. Doesn’t have ribosomes.
  • Ribosome: Small organelles that cause protein synthesis.
  • Cell Wall: Gives shape and protection to plant cells.
  • Chloroplast: Contains chlorophyll. Photosynthesis takes place here.
  • Mesosome: A folded extension of the plasma membrane in prokaryotic cells, particularly bacteria, that is thought to assist in cellular processes like DNA replication and cellular respiration.
  • Pili: Hair-like appendages found on the surface of many bacteria that serve functions ranging from attaching to surfaces to facilitating genetic exchange in a process known as bacterial conjugation.
  • Flagella: Long, whip-like structures that protrude from the cell membrane and enable mobility in various microorganisms, including some bacteria and eukaryotic cells like sperm.
  • Naked DNA: Refers to DNA strands that are not associated with proteins, typically seen in prokaryotic cells where the DNA is not enclosed in a membrane-bound nucleus.
