Across
- 2. A type of intercellular junction in animal cells, consisting of proteins surrounding a pore that allows the passage of materials between cells.
- 3. A type of motor protein that associates into filaments that interact with actin filaments to cause cell contraction.
- 4. The outer region of cytoplasm in a eukaryotic cell, lying just under the plasma membrane, that has a more gel-like consistency than the inner regions due to the presence of multiple microfilaments.
- 6. An organelle containing enzymes that transfer hydrogen atoms from various substrates to oxygen, producing and then degrading hydrogen peroxide.
- 7. junction A type of intercellular junction between animal cells that prevents the leakage of material through the space between cells.
- 8. In cilia and flagella, a large motor protein extending from one microtubule doublet to the adjacent doublet.
- 9. In plants, a thin layer of adhesive extracellular material, primarily pectins, found between the primary walls of adjacent young cells.
Down
- 1. A circular flow of cytoplasm, involving interactions of myosin and actin filaments, that speeds the distribution of materials within cells.
- 5. A large molecule consisting of a small core protein with many carbohydrate chains attached, found in the extracellular matrix of animal cells.
- 8. A type of intercellular junction in animal cells that functions as a rivet, fastening cells together.
