per._____ Date: __________
Across
1. ER with ribosomes attached to its surface
2. Tails of phospholipids that don't like water
3. water-loving heads of phospholipids
5. Made of microtubules and microfilaments to give support to cells
6. Openings in the nuclear membrane
11. Idea that all living things are made of cells
13. Digest worn out cell parts and food
16. What new cells form from?
19. made of cellulose and surrounds the outside of plant cells
20. Cells with a true nucleus
21. System of flattened sacs that modify and package proteins
26. Energy molecule made inside the mitochondria
28. Model of the plasma membrane
30. Proteins embedded in the plasma membrane
31. Fluid that makes up cytoplasm
32. This determines the function of a cell
33. Short hair-like structures made of microtubules that help move cells
34. Contain pigments in plants
35. Organelle inside the nucleus that makes ribosomes
37. Made of organs working together to do a similar job such as the digestive
40. Proteins attached to only one side of the plasma membrane
41. Region in bacteria where their chromosome is located
42. This grows faster than the surface of a cell forcing them to divide
43. Present in animal cells to aid in cell division
44. System of membranes and tubes connecting the nuclear membrane and plasma membrane
45. Site of cellular respiration in cells
46. The largest organelle in plant cells containing the cell sap
Down
1. Made of rRNA and protein and where proteins are made
2. Used a simple light microscope to draw cork cells from plants
4. Cells like bacteria without a nucleus or membrane-bound organelles
7. Made of similar cells working together to do a job such as muscle
8. All the organelles and fluid between the nucleus and plasma membrane
9. A double layer of these molecules makes up the plasma membrane
10. Smallest unit of life
12. Cell structures that perform specific functions for the cell
14. First person to see and draw living cells
15. Genetic material found inside the nucleus of a cell
17. Unattached ribosomes in the cytosol
18. Long whip-like structures found on some cells to help them move
19. Uncoiled chromosomes in the nucleus of non-dividing cells
22. Organisms made of more than one cell working together
23. Structures in the nucleus made of DNA and proteins
24. A constant internal environment maintained by cells
25. Control center of eukaryotic cells
27. surrounds the outside of all cells
29. Domain containing ancient bacterial forms
36. Small sacs containing cell products that can be transported in the cell
38. Double layer surrounding the nucleus
39. ER that makes cholesterol & helps detoxify poisons
