1. Organism-a living thing. 
2. Cell-the basic unit of structure and function in living things. 
3. Unicellular-made of a single cell. 
4. Multicellular-consisting of many cells. 
5. Stimulus-a change in an organism’s surrounding that causes 
6. Response-an action or change in behavior that occurs in reaction to a stimulus. 
7. Development-the process of change that occurs during an organism’s life to produce a more complex organism. 
8. Spontaneous generation-the mistaken idea that living things arise from nonliving sources. 
9. Autotroph-an organism that makes it own food. 
10. Heterotroph-an organism that cannot make its own food 
11. Homeostasis-the maintenance of stable internal conditions in an organism 
12. Classification-the process of grouping things based on their similarities. 
13. Taxanomy-the scientific study of how living things are classified.- 
14. Binomial nomenclature-the system for naming organisms in which each organism is given a unique, two-part scientific name. 
15. Genus-a classification grouping that consists of a number of similar, closely related species. 
16. Species-a group of organisms that are physically similar and can mate with each other and produce offspring that can also mate and reproduce. 
17. Prokaryote-an organisms whose cells lack a nucleus and some other cells structures. 
18. Nucleus-the control center of a eukaryotic cell that directs the cell’s activities and contains the information that determines the cell’s form and function. 
19. Eukaryote-an organism whose cells contain nuclei. 
20. Cell-the basic unit of structure and function in living things. 
21. Microscope-an instrument that makes small objects look larger. 
22. Cell theory-A widely accepted explanation of the relationship between cells and living things. 
23. Organelle-a tiny cell structure that carries out a specific function within the cell. 
24. Cell wall-A rigid layer of nonliving material that surrounds the cells of plants and some other organisms. 
25. Cell membrane-the outside cell boundary that controls which substances can enter or leave the cell. 
26. Cytoplasm-the material within a cell apart from the nucleus. 
27. Mitochondria-rod-shaped cell structures that convert energy in food molecules to energy the cell can use to carry out its functions. 
28. Endoplasmic reticulum-a ell structure that forms passageways in which proteins and other materials are carried through the cell. 
29. Ribosome-a small grain-like structure in the cytoplasm of a cell where proteins are made. 
30. Golgi body-a structure in a cell that receives proteins and other newly formed materials from the endoplasmic reticulum, packages them, and distributes them to other part of the cell. 
31. Chloroplast-a structure in the cells of plants and some other organisms that captures energy from sunlight and uses it to produce food. 
32. Vacuole-a sac inside a cell that acts as a storage area. 
33. Lysosome-a small, round cell structure containing chemicals that break down large food particles into smaller ones. 
34. Biogenisis- theory that living things can come only from other living things. 
35. Phylogeny- evolutionary history of an organism used to group into kingdoms 
36. Dichotomous key- a tool that can be used to determine the identity of something by answering a series of paired questions.
