  1. 2. a green pigment that captures energy from the sunlight.
  2. 4. A process of cell division that forms new nuclei, each of which has the same number of chromosomes.
  3. 5. The movement of particles against a concentration gradient and requires the cell to use energy.
  4. 8. the process by which cells use oxygen to produce energy form food.
  5. 9. the diffusion of water through a semi-permeable membrane.
  6. 10. When particles are enclosed in a vesicle and released from a cell.
  7. 11. the movement of molecules from high concentrations to low concentrations.

  1. 1. the process by which plants, algae, and some bacteria make their own food.
  2. 3. the movement of particles across the cell membrane without the use of energy by the cell.
  3. 6. the maintenance of a constant internal state in a changing environment.
  4. 7. the process by which a cell uses energy to surround a particle and enclose the particle in a vesicle to bring the particle into the cell.
