Across
- 1. membrane-bound organelles they handle waste products, taking in waste products and get rid of them
- 4. a nonmembranous body make of protein and RNA and the site of ribosome synthesis
- 5. where proteins are synthesized
- 7. Contains DNA and directs cells activities
- 11. contains no ribosomes and functions in lipid synthesis, absorption of fats, and metabolism of drugs
- 12. Boundary that holds cell contents, move substances in and out of the cell and uses signal transduction
- 15. make up most of the cell volume, a clear liquid (cytosol), cytoskeleton, and networks of membranes and organelles
- 17. transports materials within the cell, provide attachment for ribosomes and synthesizes lipids
Down
- 2. condensed DNA in which is formed during cell division
- 3. packages protein molecules for transport and secretion
- 6. the double-layered layer that contains relatively large nuclear pores
- 8. release energy from nutrient molecules and change energy into a usable form
- 9. enables a sperm cell to move
- 10. contains ribosomes and functions in protein synthesis and processing
- 13. digest worn cellular parts or substances that enter cells
- 14. near the nucleus usually in pairs and involved in the development of spindle fibers in cell division
- 16. propel fluid over cellular surfaces
