| Term | Definition |
|---|---|
| Cells | The basic unit structure and function in living things. |
| Microscope | An instrument that make smaller objects look larger made this discovery possible |
| Cell Theory | A widely accepted explanation of the relationship between cells and living things. |
| Distinguish | Two separate structure that are close together. |
| Organelle | A tiny cell structure that carries out a specific function within the cell. |
| Structure | is an arrangement and organization of interrelated elements in a material object or system, or the object or system so organized. ... Abstract structures include data structures in computer science and musical form. |
| Function | Different parts of the body that do different things. |
| Cell Wall | A layer that surrounds the Cells of Plants |
| Cell Membrane | A thin flexible barrier that surrounds a cell and controls which substances pass into and out of a cell. |
| Cytoplasm | Fills the region between the cell membrane and the nucleus. |
| Nucleus | A large oval organelle that contains the cell's genetic material in the form of DNA and controls many cell activities |
| Mitochondria | Convert energy stored in making food |
| Asexual Reproduction | by which offspring arise from a single organism, and inherit the genes of that parent only. |
| Sexual Reproduction | Two parents combine their genetic material to produce a new organism which differs from both parents. |
| Fertilization | The process in sexual reproduction in which egg cell and a sperm cell to perform a new cell. |
| Trait | A specific characteristic that an organism can pass to its offspring through its genes. |
| Gene | A sequence of DNA that determines a trait and is passed from parent to offspring. |
| Inheritance | The process by which an offspring receives from its parents. |
| Allele | A different form of a gene |
| Heredity | The passing traits from parents to offspring |
| Dominant Allele | An allele whose trait always shows up in the organism when the allele is present |
| Recessive Allele | An allele that is hidden whenever the dominant allele is present. |
| Factor | |
| Probability | A number that describes how likely it is that a particular event will occur |
| Genotype | An organism genetic makeup or allele combinations |
| Phenotype | An organism physical appearance or visible traits. |
| Chromosome | A threadlike structure within a cell's nucleus that contains DNA that is passed from one generation to the next. |
| Cell Cycle | The series of events in which a cell grows prepares for division and divides to form two daughter cells |
| Pedigree | A tool that geneticists use to map out the inheritance of traits |
| Meiosis | The process that occurs in the formation of sex cells ( sperm and egg) by which the number of chromosomes is reduced by half. |
| Chromatids | The structure formed when a chromosome divides during meiosis. |
| Mitosis | The second stage of the cell cycle during which the cell's divides into two new nuclei and one set of DNA is distributed into each daughter cell. |
| Structure | Structure is an arrangement and organization of interrelated elements in a material object or system, or the object or system so organized |
| Function | Living things would not be what they were now if they didn't function |
