Across
  1. 3. describes a solution in which extracellular fluid has higher osmolarity than the fluid inside the cell
  2. 10. a linkage between adjacent epithelial cells that forms when cadherins in the plasma membrane attach to intermediate filaments
  3. 13. the cellular organelles responsible for carrying out cellular respiration, resulting in the production of ATP, the cell’s main energy-carrying molecule
  4. 15. the darkly staining body within the nucleus that is responsible for assembling ribosomal subunits
  5. 17. a membrane-bound compartment or sac within a cell
  6. 19. describes a solution in which the extracellular fluid has the same osmolarity as the fluid inside the cell
  7. 21. a process that takes particulate matter like macromolecules, cells, or cell fragments that the cell needs from the extracellular fluid; a variation of endocytosis
  8. 24. a process that takes solutes that the cell needs from the extracellular fluid; a variation of endocytosis
  9. 26. the cell organelle that houses the cell’s DNA and directs the synthesis of ribosomes and proteins
Down
  1. 1. protein-DNA complex that serves as the chromosomes' building material
  2. 2. the network of protein fibers that collectively maintains the shape of the cell, secures some organelles in specific positions, allows cytoplasm and vesicles to move within the cell, and enables unicellular organisms to move
  3. 4. a cellular structure that carries out protein synthesis
  4. 5. structure within the nucleus that comprises chromatin that contains DNA, the hereditary material
  5. 6. a type of active transport that moves substances, including fluids and particles, into a cell
  6. 7. describes a solution in which extracellular fluid has lower osmolarity than the fluid inside the cell
  7. 8. a small, membrane-bound sac that functions in cellular storage and transport; its membrane is capable of fusing with the plasma membrane and the membranes of the endoplasmic reticulum and Golgi apparatus
  8. 9. a process of passing material out of a cell
  9. 11. a passive process of transport of low-molecular weight material down its concentration gradient
  10. 12. a membrane-bound sac, somewhat larger than a vesicle, that functions in cellular storage and transport
  11. 14. a channel that passes between the cell walls of adjacent plant cells, connects their cytoplasm, and allows materials to be transported from cell to cell
  12. 16. the long, hair-like structure that extends from the plasma membrane and is used to move the cell
  13. 18. a small, round organelle that contains hydrogen peroxide, oxidizes fatty acids and amino acids, and detoxifies many poisons
  14. 20. the transport of water through a semipermeable membrane from an area of high water concentration to an area of low water concentration across a membrane
  15. 22. a plant cell organelle that carries out photosynthesis
  16. 23. a short, hair-like structure that extends from the plasma membrane in large numbers and is used to move an entire cell or move substances along the outer surface of the cell
  17. 25. the entire region between the plasma membrane and the nuclear envelope, consisting of organelles suspended in the gel-like cytosol, the cytoskeleton, and various chemicals
