- 4. This transport requires energy to move a substance into and out of a cell.
- 5. Compounds that can be added together to make proteins.
- 7. Cells found in plants
- 11. All organisms are made of cells (one or more);
- 12. Large molecules made from stringing amino acids together.
- 16. Cells found in animals.
- 20. Very simple, single-celled bacteria that do not have a membrane-bound nucleus
- 22. Organism that is composed of many cells
- 24. Molecules that help a chemical reaction proceed.
- 26. A small structure found inside the nucleus that makes ribosomes and transports them to the cytoplasm.
- 30. The cell’s transport organelle
- 31. All of the chemical reactions that allow a cell to survive

Down
- 1. The movement of things in and out of the cell without the use of energy
- 2. Jelly-like substance in the cell containing all the organelles in the cell
- 3. Transport proteins on the cell’s membrane transport substances into and out of the cell without energy.
- 6. A type of diffusion; it is simply the process of water molecules from a higher to a lower concentration through a membrane.
- 8. A protective double membrane surrounding the nucleus that controls the flow of materials in and out of the nucleus.
- 9. Much more complex types of cells
- 10. The cell’s powerhouse
- 13. In plant cells only, they are organelles that produce food.
- 14. The movement of molecules from an area of high to low concentration
- 15. The chemical reaction a plant carries out in order to produce energy from sunlight
- 17. Glucose in food reacts with oxygen, producing carbon dioxide, water and energy in the mitochondria
- 18. The basic structural and functional unit of all forms of life
- 19. Plants, algae, fungi and some bacteria have an extra computer layer that is very rigid and tough
- 21. Another chemical reaction where energy is released through the breakdown of food
- 23. Organelle that contains digestive chemicals that break down food, cell waste
- 25. Protein-making factories in a cell.
- 27. The parts of a cell.
- 28. Moving things inside and outside of the cell membrane.
- 29. In every cell, there is a layer on the outside of the cell that holds the cell together
- 33. The cell’s packaging, sorting, and distributing organelle
- 34. The cell’s “control center”
