Cells

6. A simple organic compound containing both a carboxyl (—COOH) and an amino (—NH2) group.
7. A sweet, syrupy liquid obtained from animal fats and oils or by the fermentation of glucose. It is used as a solvent, sweetener, and antifreeze and in making explosives and soaps
8. The building blocks of nucleic acids; they are composed of three subunit molecules: a nitrogenous base, a five-carbon sugar (ribose or deoxyribose), and at least one phosphate
9. A class of lipids that are a major component of all cell membranes
11. Sugars used by organisms for energy
14. A molecule that can be bonded to other identical molecules to form a polymer
16. A large oval structure found in both plant and animal cells. It acts as the ''brain'' of the cell
17. Detects a signal molecule and carries out an action in response
18. a nutrient found in food (as meat, milk, eggs, and beans)
19. The building blocks of the fat in our bodies and in the food we eat

1. A complex organic substance present in living cells, especially DNA or RNA, whose molecules consist of many nucleotide linked in a long chain
2. A long, single-stranded chain of cells that processes protein
3. This strengths the cell membrane
4. A molecule containing a very large number of atoms, such as a protein, nucleic acid, or synthetic polymer.
5. A large group of organic compounds that are oily and includes fatty acids, oils, waxes, sterols, and triglycerides
10. A group of two or more cells working together to do a specific job
12. What are the sugars, starches and fibers found in fruits, grains, vegetables and milk products
13. Large molecules made of many smaller molecules of the same kind
15. A molecule that contains the instructions an organism needs to develop, live and reproduce
20. Wall The rigid layer of material that surrounds plant cells
