- intermediate filament
- a A hollow rod of tubulin protein in the cytoplasm of all eukaryotic cells and in cilia, flagella, and the cytoskeleton.
- b A layer of exopolysaccharide fibers on the surface of bacterial cells which may be involved in adherence to a surface. Sometimes a general term for a bacterial capsules; if compact called capsule and if diffuse, called slime layer
- c A coiled, spiral-shaped bacterium that has endoflagella and flexes as it moves.
- d unstructured semifluid substance that fills the space between cells in connective tissues or inside organelles, the surface area exposed to fluids, such as where the production of energy takes place, in a mitochondrion
- e rope-like assemblies of fibrous polypeptides in the cytoskeleton that provide support and strength to cells; A component of the cytoskeleton that includes all filaments intermediate in size between microtubules and microfilaments.
5 Multiple choice questions
- enzyme-filled vesicle in which fatty acids and amino acids are metabolized to hydrogen peroxide that is broken down to harmless products
- A temporary, foot-like extension of a cell, used for locomotion or engulfing food
- the smallest unit that can perform all life processes; cells are covered by a membrane and contain DNA and cytoplasm
- an area within a chloroplast that lies between the thylakoid membranes; serves as the site of the Calvin cycle in photosynthesis which involves the synthesis of carbohydrates
- muscle protein filament in a sarcomere; its movement shortens the sarcomere, yielding muscle contraction. Actin filaments play a role in the movement of the cell and its organelles
5 True/False questions
coccus → any spherical or nearly spherical bacteria
flagellum → a lash-like appendage used for locomotion (e.g., in sperm cells and some bacteria and protozoa)
apoptosis → any spherical or nearly spherical bacteria
motor molecule → protein that moves along either actin filaments or microtubules and translocates organelles
cristae → A sticky layer that surrounds the cell walls of some bacteria, protecting the cell surface and sometimes helping to glue the cell to surfaces.
