Across 3. in a eukaryotic cell, one of the structures in the nucleus that are made up of DNA strands that are loosely coiled such that translation and transcription can occur 8. the region of the cell within the membrane that includes the fluid, the cytoskeleton, and all of the organelles except the nucleus 12. an organism made up of cells that have a nucleus enclosed by a membrane, multiple chromosomes, and a mitotic cycle; eukaryotes include animals, plants, and fungi but not bacteria or archaea 13. a cell organelle composed of RNA and protein; the site of protein synthesis 14. cell organelle that helps make and package materials to be transported out of the cell 15. the double-membrane that surrounds the nucleus of a eukaryotic cell

Down 1. a double layer of phospholipids that makes up plasma and organelle membranes 2. a collection of tissues that carry out a specalized function of the body 3. an organelle that is composed of two short microtubules at right angles to each other and that has an active role in mitosis 4. one of the small bodies that are found in the cytoplasm of a cell and that are specialized to perform a specific function 5. the soluble portion of the cytoplasm, which includes molecules and small particles, such as ribosomes, but not the organelles covered with membranes 6. a collection of specialized cells and cell products that perform a specific function 7. cell's outer boundary 9. in eukaryotic cells, the cell organelle that is surrounded by two membranes and that is the site of cellular respiration, which produces ATP 10. a single-celled organism that has no nucleus and has no membrane-bound orangelles 11. in a eukaryotic cell, a membrane-bound organelle that contains the cell's DNA and that has a role in processes such as growth, metabolism, and reproduction
