    This consists of a network of protein fibers that gives the cell its structural framework.

    Cytoskeleton

  • 9

    These consist of helically arranged globular proteins called .

    tubulin

  • 10

    is a helix of a-tubulin and B-tubulin subunits.

    Microtubule

  • 11

    They consist of long fibers of __ protein, making them the thinnest cytoskeleton.

    actin

  • 12

    • They help facilitate cell and organelle movement. • They can help change the shape of the cell.

    Microfilaments

  • 13

    • Helps maintain cell shape • Anchors the nucleus provide structural integrity to the plasma membrane

    Intermediate filaments

  • 14

    This is where all different subcellular structures are suspended.

    Cytoplasm

  • 15

    is a rigid structure that surrounds the cell membrane. • It helps maintain the shape of cells and prevent them from bursting.

    Most bacteria have cell wall made up of___.

    peptidoglycan

  • 17

    The cell wall in some fungi consists of ___.

    chitin

  • 18

    In plant cells, the cell wall consists of mesh-like ___ fibers.

    cellulose

  • 19

    ___ prevent the cell from bursting should excess water is absorbed.

    Plant cell walls

  • 20

    • This is a prominent, usually oval structure in a eukaryotic cell. • It is located in almost the center of the cell.

    Nucleus

  • 21

    is the semifluid matrix.

    Nucleoplasm

  • 22

    __ separates the nucleus from the cytoplasm

    Nuclear envelope

    ___ are attached to the outside of the endoplasmic reticulum or nuclear envelope.

    Bound ribosomes

  • 27

    These serve functions similar to a warehouse and processing center, processing products of the ER.

    Golgi Bodies

  • 28

    These contain enzymes and serve as metabolic assistance to organelles and specialize in synthesizing & breaking down lipids.

    Peroxisomes

  • 29

    These serve as a storage of water, organic nutrients,variety of salts, sugar & some weak acids.

    Vacuoles

  • 30

    This is known as the "powerhouse of the cell"
