Cell Organelles Cell Organelles Presentation Transcript

  • Chris Word Jennie Lee Gruber Jesse Fender Tessa Hunt Alex Batory Cell Organelles
    • In eukaryotic cells, the central membrane-bound organelle that manages cellular functions and contains DNA.
    Nucleus
    • Flexible boundary between the cell and its environment; allows materials such as water and nutrients to enter and waste products to leave.
    Plasma Membrane
    • Eukaryotic membrane-bound organelles that transform energy stored in food molecules; has a highly folded inner membrane that produces energy-storing molecules.
    Mitochondria
    • Cellular framework found within the cytoplasm composed of microtubules and microfilaments.
    Cytoskeleton
    • Organelles that contain digestive enzymes; digest excess or worn out organelles, food particles, and engulfed viruses or bacteria.
    Lysosome
    • Chlorophyll-containing organelles found in the cells of green plants and some protists; capture light energy and converted it to chemical energy.
    Chloroplasts
    • Organelle in eukaryotic cells with a system of flattened tubular membranes; sorts and packs proteins and sends them to their appropriate destinations.
    • Membrane-bound space in the cytoplasm of cells used for the temporary storage of materials.
    Vacuoles
    • The ribosome free part of the endoplasmi reticulum that takes part in the synthesis of various lipids (e.g., for building membranes such as phospholipids), fatty acids and steroids (e.g., hormones), and also plays an important role in carbohydrate metabolism, detoxification of the cell (enzymes in the smooth ER detoxify chemicals), and calcium storage. It is well developed in cells that produce steroid hormones and in liver cells. It also is a large transporter of nutrients found in the cell.
    Smooth ER
    • The portion of the endoplasmic reticulum studded with ribosomes that manufactures and transports proteins destined for membranes. These ribosomes insert proteins into the lumen of the ER where the ER helps modify and fold the protein.
    • Nonmembrane-bound organelles in the nucleus where proteins are assembled.
    • Clear, gelatinous fluid in cells that is the site of numerous chemical reactions; in eukaryotic cells, it suspends the cell’s organelles.
    • Fairly rigid structure located outside the plasma membrane of plants, fungi, most bacteria, and some protists; provides support and protection.
    • Organelle in eukaryotic cell nucleus that produces ribosomes.
    • Thin, hollow cylinders made of protein that provide structural support for eukaryotic cells.
    • Thin, solid protein fibers that provide structural support for eukaryotic cells.
    • Long projections composed of microtubules; found on some cell surfaces; they help propel cells and organisms by a whip like motion.
    • Group of plant organelles that are used for storage of starches, lipids, or pigments.
    • In animal cells, a pair of small cylindrical structures composed of microtubules that duplicate during inter phase and move to opposite ends of the cell during prophase.
    Centrioles
    • Short, numerous, hair like projections composed of pairs of microtubules; frequently aid on locomotion.
    Cilia
