Study Notes
Cell Reproduction
- Binary Fission: DNA pinches equally into two
- Cell Cycle: Cytokinesis, Interphase, Mitosis
- Cytokinesis: Cell division, pinching off
- G1, S, G2: Phases in the cell cycle
- Interphase: G1, S, and G2; all stages before mitosis
- Mitosis: Cell nucleus division
- Asexual Reproduction: Creates identical offspring or clones; example: mitosis
- Centriole: Organelle that forms spindle fibers
- Centromere: Point where sister chromatids attach
- Chromatin: Unwound DNA
- Chromosome: Tightly wrapped DNA
- Gametes: Sex cells (sperm and egg)
- Zygote: Fusion of sperm and egg
- Haploid: Half the normal chromosome number
- Diploid: Full chromosome number
- Homologous Chromosomes: Identical chromosomes; crossing over
- Meiosis: Somatic cell division (body cells-skin, muscle, bone)
- Prophase
- Metaphase
- Anaphase
- Telophase
- Spindle Fibers: Structure in cells that separates chromosomes
- Spores
- Vegetative Propagation: New plant fragment from original plant
- Cancer cell cycle timing
- Chromatid
- Differentiation: Process where cells become specialized
- Daughter cells: Result of cell division
- Benign/Malignant: Types of tumors
- Tumor: Abnormal mass of cells
- Karyotype: Complete set of chromosomes
- Centriole: Cell organelle involved in cell division
- Nondisjunction: Error in chromosome separation
- Stem Cell: Undifferentiated cell with the potential to become various types of cells
