5. 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.
6. the movement of molecules from high concentrations to low concentrations.
8. The movement of particles against a concentration gradient and requires the cell to use energy.
10. the maintenance of a constant internal state in a changing environment.
11. a group of similar cells that preform a common function.
15. the process by which cells use oxygen to produce energy form food.
16. a structure made up of a collection of two or more tissues that carries out a specialized function.

1. the movement of particles across the cell membrane without the use of energy by the cell.
2. A process of cell division that forms new nuclei, each of which has the same number of chromosomes.
3. When particles are enclosed in a vesicle and released from a cell.
4. the process by which plants, algae, and some bacteria make their own food.
7. a group of two or more organs that work together to perform body functions.
9. the arrangement of parts in an organism or an object.
