Across
  1. 2. + O2 → CO2 +
  2. 4. Transport-the movement of substances across a cell membrane in such a way that it does not require energy, substances move down a concentration gradient (from areas of high concentration to areas of low concentration).
  3. 6. organelle that makes proteins for a cell, found in plants, animals and bacteria.
  4. 8. of energy for a cell
  5. 10. Membrane-A semi-permeable membrane that helps to control what goes into and out of a cell.
  6. 11. + H20 → C6H12O6 + O2
  7. 14. organelle that contains DNA and controls the activities of the cell.
  8. 15. organelle found only in plant cells that uses the sun’s energy to make sugar in a process called photosynthesis.
  9. 18. structures found in a cell that perform a specific function for that cell.
  10. 21. by which sugar is broken down to produce energy in the absence of oxygen.
  11. 22. Transport-the movement of substances across a cell membrane in such a way that it requires energy, substances move against a concentration gradient (from areas of low concentration to areas of high concentration).
  12. 23. movement of water from areas of high concentration of water (low solute concentration) to areas of low concentration of water (high solute concentration)
  13. 24. Protein-proteins that are found in the cell membrane that help to carry large molecules into and out of the cell.
Down
  1. 1. organelles that stores substances, such as water, for a cell.
  2. 3. not require oxygen
  3. 5. Gradient-The gradual change in the concentration of a solute between different regions of a solution.
  4. 7. organelle found in plant and animal cells that breaks down sugar to produce energy (ATP) in a process called cellular respiration.
  5. 9. Respiration-process by which a molecule of glucose is broken down to produce energy in the form of ATP, occurs mostly in mitochondria
  6. 12. by which the sun’s energy is used to make a molecule of glucose, occurs in chloroplasts
  7. 13. Bilayer-the main structural component of the cell membrane, composed of two layers of phospholipids that are arranged tail-to-tail
  8. 16. oxygen
  9. 17. organelle that breaks down or digests substances for a cell.
  10. 19. type of active transport that moves substances out of the cell through the use of membrane-bound vesicles.
  11. 20. type of active transport that moves substances into a cell using the cell membrane, there are two types – phagocytosis and pinocytosis.
