Across

1. A protein that speeds up chemical reactions in cells, yet remains unchanged

7. Movement of materials, using energy, through the cell membrane through transport proteins

10. Folded membrane that moves materials around in a cell

12. Organisms that can't make their own food are called this

14. Stacks of membrane covered sacs that package and move proteins outside the cell

16. The form of respriration that converts energy from glucose without oxygen

19. The process in which a nucleus divides to form two identical nuclei

22. The movement of water through a cell membrane

23. Big proteins & bacteria are enclosed by the cell membrane & taken inside in a vacuole in this process

24. Plant organelle in which light energy is changed into chemical energy

26. Large structures in a cell's cytoplasm in eukaryotic cells

27. Occurs when molecules are spread evenly throughout a substance or space

28. The movement of molecules from places where they are more to places where there are less

29. Compounds made up of elements other than carbon

30. Genetic bluepronts for the operations of the cell are on these long strands in the nucleus

31. Rigid structure outside the cell membrane that supports & protects a plant cell

Down

2. A combination of substances in which individual substances retain their properties, ex. sugar in salt

3. An organism that makes its own food, mainly using sunlight, is called this

4. Food molecules are broken down & energy is released in these organelles

5. Make up all living things...4 groups, lipids, carbohydrates, proteins, & nucleic acids.

6. Structures in the nucleus that contain DNA

8. Stucture, made of a double layer of fats with some proteins, that makes the outer boundary of the cell

9. Largest organelle in a cell, only found in eukaryotic cells

11. Movement of particles across a cell membrane by diffusion, no energy used

13. Gel-like material inside the cell, yet outside the nucleus

15. This form of reproduction occurs without sex

17. Small protein making structure in the cytoplasm

18. Groups of cells that do similar work are called this

20. Wastes & proteins are packaged, fuse with the cell membrane, & are released outside the cell in this process

21. The total of all cell processes in an organism that allow it to stay alive, grow, & reproduce are called this

25. Organielle that digests wastes & worn out cell parts
