| cell | Basic structural and function of all living things. |
| animal cell | contains a nucleus, cell membrane, and cytoplasm. |
| plant cell | contains a nucleus, a cell membrane, chloroplast enclosed in a cell wall. |
| nucleus | cpntrol center of the cell. |
| cell membrane | surrounds the cell and allows certain materials in and out of the cell |
| cytoplasm | the living,gel-like fluid inside the cell that contains all the organelles. |
| cell wall | the tough outer covering of a cell that shape, supports and protects the cell. |
| cellular respiration | chemical process in which glucose and oxygen are broken down to form water, carbon dioxide, and most importantly, energy |
| photosynthesis | series of chemical reactions during which glucose is formed from sunlight, water, carbon dioxide and chlorophyll |
| mitosis | formation of two new cells that are identical to the original cell |
| meiosis | reduction division in which a cell divides into new cells, each of which has half as many chromosomes as the original cell. |
| mRNA | transcribed using DNA as atemplate |
| ribosomes | organelle where proteins are made |
| unicellular | organisms made of one cell |
| multicellular | organisms containing many cella |
| sexual reproduction | male and female gametes unite to produce a unique organism with a complete set of chromosomes |
| asexual reproduction | production of offspring from a single parent |
| sex-linked traits | females can carry the trait and pass it on to offsprings without having the trait |
| DNA | nucleic acid that carries the genetic code, and is used in the making of proteins. |
| heredity | transmission of traits from parents to offspring |
