1. Biology the study of life
2. Eukaryote an organism made up of cells that have a nucleus enclosed by a membrane,
multiple chromosomes, and a mitotic cycle; eukaryotes include animals,
plants, and fungus but not bacteria
3. Multicellular describes a tissue, organ, or organism that is made of many cells
4. Prokaryote a single-celled organism that has no nucleus and has no membrane-bound
organelles; examples include bacteria and archaea
5. Unicellular describes an organism that consists of a single cell
6. Asexual Reprduction reproduction that doesn't involve the Union of gamete and in which a single
parent produces offspring that are genetically identical to the parent
7. DNA The material that contains the information that determines inherited char-
acteristics
8. Evolution a heritable change in the characteristics within a population from one
generation to the next; the development of new types of organisms from
preexisting types of organisms over time
9. Sexual Reproduction reproduction in which gametes from two parents unite
10. Tissue a collection of specialized cells and cell products that perform a specific
function
11. Organ a collection of tissues that carry out a specialized function of the body
12. Organ System a group of organs that accomplish related tasks
13. Organism an independent individual that possesses all the characteristics of life
14. Cell

the smallest unit that can perform all life processes; its covered by a mem-
brane and contain DNA and cytoplasm
15. Chloroplast an organelle found in plant and algae cells where photosynthesis occurs
16. Golgi Apparatus cell organelle that helps make and package materials to be transported out
of the cell
17. Mitochondria In eukaryotic cells, the cell organelle that is surrounded by two membranes
and that is the site of cellular respiration, which produces ATP
18. Nucleus in a eukaryotic cell, a membrane-bound organelle that contains the cell's
DNA and has a role in processes such as growth, metabolism, and repro-
duction
19. Ribosome a cell organelle composed of RNA and protein; the site of protein synthesis
20. Cohesion The force that holds molecules of a single material together
21. Hydrogen Bonds The intermolecular force occurring when a hydrogen atom(+) on one mol-
ecule bonds with a partially negative atom on another molecule. Example:
happens between water molecules; happens between strands of DNA
22. Polar Describes a molecule with opposite charges on opposite ends
23. Monomer A molecule that can be bonded to other identical molecules to form a
polymer
24. Organic Macromole- A molecule of the kind normally found in living systems; usually composed
cule of carbon atoms in rings or long chains to which are attached to other atoms
such as hydrogen, oxygen, and nitrogen
25. Polymer a large molecule that is formed by more than five monomers, or small units
26. Hydrolysis Type of reaction that adds water to break down a polymer

27. Carbohydrate any organic compound that is made of carbon, hydrogen, and oxygen and
that provides nutrients to the cells of living things
28. Protein an organic compound that is made of one or more chains of amino acids
and that is a principal component of all cells
29. Lipid A large, nonpolar organic molecule including fats and steroids; store energy
and make up cell membranes
30. Nucleic acid An organic compound either RNA/DNA whose molecules are made up of
one or two chains of nucleotides and carry genetic information
31. Amino acid An organic molecule that contains a carboxyl and an amino group that makes
up proteins
32. Enzyme A type of protein that speeds up metabolic reactions in plants and animals
without being permanently changed or destroyed
33. Activation energy The minimum amount of energy required to start a chemical reaction, it is
lowered by an enzyme.
34. pH A range of values that are used to express the acidity or alkalinity of a
substance
35. Active site The site on an enzyme that attaches to a substrate
36. carbohydrate function quick energy, monsacharides, disacharides and polysacharides
37. passive transport diffusion, osmosis, facilitated diffusion are types of this transport
38. active transport endocytosis and exocytosis are types of this transport
39. dehydration synthe- Type of reaction that removes a water to build a molecule
