5 Matching Questions
- prokaryotic cell
- central vacuole
- actin filament
- a 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
- b A short cellular appendage specialized for locomotion, formed from a core of nine outer doublet microtubules and two inner single microtubules ensheathed in an extension of plasma membrane.
- c A membrane-enclosed sac occupying most of the interior of a mature plant cell, having diverse roles in reproduction, growth, and development.
- 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 A type of cell lacking a membrane-enclosed nucleus and membrane-enclosed organelles; found only in the domains Bacteria and Archaea.
5 Multiple Choice Questions
- protein that moves along either actin filaments or microtubules and translocates organelles
- aerobic rod-shaped spore-producing bacterium
- idea that all living things are composed of cells, cells are the basic units of structure and function in living things, and new cells are produced from existing cells
- a microscopic network of actin filaments and microtubules in the cytoplasm of many living cells that gives the cell shape and coherence
- A coiled, spiral-shaped bacterium that has endoflagella and flexes as it moves.
5 True/False Questions
microtubule → membrane-bound sac that buds from the endoplasmic reticulum or the Golgi apparatus, storage structures for food, water, minerals, waste
lysosome → plasma membrane that folds into the cytoplasm and increases surface area
chromosome → A threadlike linear strand of DNA and associated proteins in the nucleus of eukaryotic cells that carries the genes and functions in the transmission of hereditary information
chromoplast → type of plastid that synthesizes and stores red, yellow, and orange pigments, responsible for colors of many fruits and flowers
coccus → any spherical or nearly spherical bacteria
