Across
  1. 3. respiration- A series of chemical reactions that convert the energy in food molecules into a usable form of energy called ATP.
  2. 6. Part of a eukaryotic cell that directs cell activity and contains genetic information stored in DNA.
  3. 7. Substance in cells that forms when many small molecules join together.
  4. 9. The movement of substances from an area of higher concentration to an area of lower concentration.
  5. 11. The process during which a cell’s vesicles release their contents outside the cell.
  6. 14. Membrane-surrounded component of a eukaryotic cell with a specialized function.
  7. 15. The process during which a cell takes in a substance by surrounding it with the cell membrane.
  8. 16. diffusion- The process by which molecules pass through a cell membrane using special proteins called transport proteins.
Down
  1. 1. wall- A stiff structure outside the cell membrane that protects a cell from attack by viruses and other harmful organisms.
  2. 2. The diffusion of water molecules only through a membrane.
  3. 3. theory- The theory that states that all living things are made up of one or more cells, the cell is the smallest unit of life, and all new cells come from preexisting cells.
  4. 4. transport- The movement of substances through a cell membrane using the cells energy.
  5. 5. transport- The movement of substances through a cell membrane without using the cell’s energy.
  6. 8. membrane- A flexible covering that protects the inside of the cell from the environment outside the cell.
  7. 10. The liquid part of a cell inside the cell membrane; contains salts and other molecules.
  8. 12. A membrane-bound organelle that uses light energy and makes food-a sugar called glucose-from water and carbon dioxide in a process known as photosynthesis.
  9. 13. A series of chemical reactions that convert light energy, water, and carbon dioxide into the food-energy molecule glucose and give off oxygen.
