Cells
Across
1. system of membranes and tubes connecting the nuclear membrane and plasma
membrane
4. structures in the nucleus made of DNA and proteins
6. region in bacteria where their chromosome is located
7. model of the plasma membrane
9. proteins attached to only one side of the plasma membrane
14. tails of phospholipids that don't like water
16. made of cellulose and surrounds the outside of plant cells
18. idea that all living things are made of cells
21. genetic material found inside the nucleus of a cell
23. contain pigments in plants
24. ER with ribosomes attached to its surface
30. this grows faster than the surface of a cell forcing them to divide
33. digest worn out cell parts and food
35. a double layer of these molecules makes up the plasma membrane
36. first person to see and draw living cells
37. small sacs containing cell products that can be transported in the cell
38. cells with a true nucleus
39. water-loving heads of phospholipids
40. cells what new cells form from
41. made of organs working together to do a similar job such as the digestive
44. present in animal cells to aid in cell division
Down
2. surrounds the outside of all cells
3. organisms made of more than one cell working together
5. cells like bacteria without a nucleus or membrane-bound organelles
8. cell structures that perform specific functions for the cell
10. domain containing ancient bacterial forms
11. this determines the function of a cell
12. all the organelles and fluid between the nucleus and plasma membrane
13. site of cellular respiration in cells
15. double layer surrounding the nucleus
17. energy molecule made inside the mitochondria
18. short hair-like structures made of microtubules that help move cells
19. a constant internal environment maintained by cells
20. made of similar cells working together to do a job such as muscle
22. long whip-like structures found on some cells to help them move
25. system of flattened sacs that modify and package proteins
26. ER that makes cholesterol & helps detoxify poisons
27. fluid that makes up cytoplasm
28. organelle inside the nucleus that makes ribosomes
29. made of rRNA and protein and where proteins are made
30. made of microtubules and microfilaments to give support to cells
31. openings in the nuclear membrane
32. smallest unit of life
34. uncoiled chromosomes in the nucleus of non-dividing cells
39. used a simple light microscope to draw cork cells from plants
42. control center of eukaryotic cells
43. unattached ribosomes in the cytosol
44. the largest organelle in plant cells containing the cell sap
45. proteins embedded in the plasma membrane
