Unit 2 Chapter 6 (2)

4. A network of microtubules, microfilaments, and intermediate filaments
6. A structure in the centrosome of an animal cell composed of a cylinder of microtubule triplets arranged in a “9 + 0” pattern.
8. A long cellular appendage specialized for locomotion
10. A type of intercellular junction in animal cells, consisting of proteins surrounding a pore that allows the passage of materials between cells.
11. A type of motor protein that associates into filaments that interact with actin filaments to cause cell contraction.
13. The outer region of cytoplasm in a eukaryotic cell, lying just under the plasma membrane
14. A specialized structure in the nucleus, consisting of chromosomal regions

1. A type of cell lacking a membrane-enclosed nucleus and membrane-enclosed organelles
2. In animal cells, a transmembrane receptor protein with two subunits that interconnects the extracellular matrix and the cytoskeleton.
3. In a mature plant cell, a large membranous sac with diverse roles in growth, storage, and sequestration of toxic substance
4. A glycoprotein in the extracellular matrix of animal cells that forms strong fibers, found extensively in connective tissue and bone
5. A protective layer external to the plasma membrane in the cells of plants, prokaryotes, fungi, and some protists
7. An infolding of the inner membrane of a mitochondrion. The inner membrane houses electron transport chains and molecules of the enzyme catalyzing the synthesis of ATP
9. A membranous sac formed by phagocytosis of microorganisms or particles to be used as food by the cell.
12. A stack of membrane-bounded thylakoids in the chloroplast.
