6. a green pigment that captures energy from the sunlight.
7. the arrangement of parts in an organism or an object.
10. the movement of particles across the cell membrane without the use of energy by the cell.
11. the maintenance of a constant internal state in a changing environment.
13. The movement of particles against a concentration gradient and requires the cell to use energy.
14. the diffusion of water through a semi-permeable membrane.
15. When particles are enclosed in a vesicle and released from a cell.
17. 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.

1. a group of similar cells that preform a common function.
2. the process by which cells use oxygen to produce energy form food.
3. the process by which plants, algae, and some bacteria make their own food.
4. the activity of each part in an organism.
5. a group of two or more organs that work together to perform body functions.
8. the movement of molecules from high concentrations to low concentrations.
9. a living thing that can carry out life processes by itself.
12. a structure made up of a collection of two or more tissues that carries out a specialized function.
16. A process of cell division that forms new nuclei, each of which has the same number of chromosomes.
