Across
- 7. vesicular transport that brings substances out of the cell
- 8. gel-like substance that surrounds the nucleus and contains various organelles and molecules
- 10. the "building blocks" of DNA
- 12. this occurs due to differences in pressure
- 13. movement of particles from high concentration to low concentration
- 15. solution where concentration of solutes is lower than the blood
- 17. the diffusion of water down a concentration gradient
- 18. solution where concentration of solutes is higher than the blood
- 22. this receives proteins from the endoplasmic reticulum and prepares them for export to other parts of the body
- 24. the only nucleotide that can pair with adenine
- 25. this type of cell are elongated thread-like fibers that can shorten to allow movement of the body
- 26. network of membranous canals and curving sacs
Down
- 1. this type of cell recognizes and destroys foreign invaders
- 2. large particles are trapped in a portion of the plasma membrane and brought into the cell
- 3. these molecules have hydrophilic heads and hydrophobic tails and form the plasma membrane
- 4. the only nucleotide that can pair with cytosine
- 5. contain enzymes that convert organic compounds to adenosine triphosphate (ATP)
- 6. the point at which no further diffusion occurs
- 9. stage of cell cycle when the centromeres divide
- 11. vesicular transport that brings substances into the cell
- 14. this is the substance that fills the nucleus
- 16. this type of cell transmits electrical impulses from one part of the body to another
- 19. this substance helps stiffen and strengthen the plasma membrane
- 20. this type of cell stores and releases substances such as hormones enzymes mucus and sweat
- 21. solution where concentration of solutes is the same as the blood
- 23. fluid and dissolved particles are trapped in the plasma membrane and brought into the cell
