1. Homeostasis—the maintenance of stable internal conditions in an organism

2. Cell—the basic unit of structure and function in living things

3. Facilitated Diffusion—diffusion of glucose molecules through the cell membrane with the help of proteins. Does not require energy.

4. Endocytosis—process by which a cell takes in a substance by surrounding it with the cell membrane.

5. Exocytosis—process by which vesicles release their contents outside the cell.

6. Osmosis—the diffusion of water molecules through a selectively permeable membrane

7. Active transportation—the movement of materials through a cell membrane using energy

8. Passive transportation—the movement materials through a cell membrane without using the cell’s energy

9. Diffusion—the process by which molecules move from an area of higher concentration to an area of lower concentration

10. Cell Theory—a widely accepted explanation of the relationship between cells and living things.

11. Respiration—the process by which cells break down simple food molecules to release the energy they contain

12. Photosynthesis—the process in which some organisms use water along with sunlight and carbon dioxide to make their own food

13. Fermentation—the process by which cells break down molecules to release energy without using oxygen

14. Cell Wall—a rigid layer of nonliving material that surrounds the cells of plants and some other organisms. Provides strength and support.

15. Cell Membrane—the outside cell boundary that controls which substances can enter or leave the cell.

16. Nucleus—the control center of a eukaryotic cell that directs the cell’s activities and contains DNA.

17. Mitochondria—rod-shaped cell structures that convert energy in food molecules to energy the cell can use to carry out its functions. Where the 2nd stage of respiration takes place.

18. Chloroplast—a structure in the cells of plants and some other organisms that captures energy from sunlight and uses it to produce food.

19. Vacuole—a sac inside a cell that stores food, water, wastes, and enzymes. In plants there is one large central vacuole and in animals there are multiple smaller ones.

20. Organelle—a tiny cell structure that carries out a specific function within the cell.

21. Cytoplasm—the material within the cell apart from the nucleus. Aids in transportation and is where the first part of respiration takes place.

22. Mitosis—when body (somatic) cells divide into two new cells and one copy of the DNA is distributed into each daughter cell.

23. Meiosis—the process that occurs in the formation of sex cells (sperm and egg) by which the number of chromosomes is reduced by half.

24. Element – any substance that cannot be broken down into simpler substances. (Ex: Carbon)

25. Compound – when two or more elements combine chemically (Ex: water)
