| algae | Plant-like protists. |
| binary fission | a form of asexual reproduction in which one-cell divides to form two identical cells. |
| binomial nomenclature | The naming system for organisms in which each organism is given a two-part name-a genus name and a species name. |
| budding | A form of asexual reproduction in which a new organism grows out of the body of a parent. |
| cilia | the hair-like projections on the outside of cells that move in a wavelike manner. |
| classification | the process of grouping things based on their similarities. |
| conjugation | The process in which a unicellular organism trasfers some of its genetic material to another unicellular organism. |
| cotyledon | A seed leaf that stores food. |
| Decomposer | An organism that breaks down large chemicals from dead organisms into small chemials and returns important materials to the soil and water. |
| embryo | The young organism that develops from a zygote. |
| endospore | A small, rounded, thick-walled, resting cell that forms inside a bacterial cell. |
| fertilization | The joining of a sperm cell and an egg cell. |
| flagellum | A long, whip-like structure that helps a unicellular organism move. |
| flower | The reproductive structure of an angiosperm. |
| fruit | The ripened ovary and other structures that enclose one or more seeds of an angiosperm. |
| genus | A classification grouping that consists of a number of similar, closely related species. |
| hormone | The chemical product of an endocrine gland that speeds up or slows down the activities of an organ or tissue; also, a chemical that affects a plant's growth and development. |
| host | An organism that provides a source of energy or a suitable environment for another organism to live. |
| hyphae | Branching thread-like tubes that make up the bodies of multi-cellular fungi. |
| ovule | A plant structure in seed plants that contains an egg cell. |
| parasite | An organism that lives on or in a host and causes harm to the host. |
| pistil | The female reproductive part found in the petals of a flower in a seed producing plant. |
| pollen | Tiny particles produced by plants that contain the microscopic cells that later become sperm cells. |
| protozoan | An animal-like protist. |
| pseudopod | A "false-foot" or temporary bulge of the cell membrane used for feeding and movement in some protozoan. |
| seed | The plant structure that contains a young plant inside a protective covering. |
| spore | A tiny cell that is able to grow into a new organism. |
| species | A group of similar organisms whose members can mate with one another and produce fertile offspring. |
| stamen | The male reproductive parts of a flower. |
| taxonomy | The scientific study of how living things are classified. |
| tropism | The growth response of a plant toward or away form a stimulus. |
| vascular tissue | The internal transporting tissue in some plants that is made up of tube-like structures. |
| zygote | A fertilized egg, produced by the joining of a sperm cell and egg cell. |
