Across
- 3. A membrane bound organelle that uses light energy and makes food-a sugar called glucose- from water and carbon dioxide in a process called photosynthesis.
- 5. Membrane: A flexible covering that protects the inside of a cell from the environment outside the cell.
- 8. The diffusion of water molecules only through a membrane.
- 9. Theory: The theory that states that all living things are made of one or more cells, the cell is the smallest unit of life, and all new cells come from preexisting cells.
- 12. Transport: The movement of substances through a cell membrane using the cell’s energy.
- 13. (pg.509): Part of a eukaryotic cell that directs cell activity and contains genetic information stored in DNA.
- 14. Wall: A stiff structure outside the cell membrane that protects a cell from attack by viruses and other harmful organisms.
- 15. Diffusion: The process by which molecules pass through a cell membrane using special proteins called transport proteins.
- 16. A series of chemical reactions that convert light energy, water, and carbon dioxide into the food-energy molecule and given off oxygen.
Down
- 1. Membrane-surrounded component of a eukaryotic cell with a specialized function.
- 2. Substance in cells that forms when many small molecules join together.
- 4. The process during which a cell’s vesicles release their contents outside the cell
- 6. The liquid part of a cell inside the cell membrane; contains salts and other molecules
- 7. Transport: The movement of substances through a cell membrane without the cell’s energy.
- 9. Respiration: A series of chemical reactions that convert the energy in food molecules into a usable form of energy called ATP.
- 10. The movement of substances from an area of higher concentration to an area of lower concentration.
- 11. The process by which a cell takes in a substance by surrounding it with the cell membrane.
