Study Notes
Cell Division
- Binary Fission: DNA pinches equally into two
- Cell Cycle: Cytokinesis, Interphase, Mitosis
- Cytokinesis: Cell division; pinching off of new cells
- G1, S, G2: Phases of interphase
- Interphase: G1, S, and G2 phases; all together
- Mitosis: Nuclear division
- Asexual reproduction: Creates identical copies
- Centriole: Organelle that creates spindle fibers
- Centromere:
- Chromatin: Unwound DNA
- Chromosome: Tightly wrapped DNA
- Gametes: Sex cells; sperm, eggs
- Zygote: Formed by the union of sperm and egg
- Haploid: Half the normal chromosome number
- Diploid: Full chromosome number
- Homologous: Identical chromosomes
- Crossing over: Exchange of genetic material during meiosis
- Meiosis: Cell division that produces gametes; somatic cells
- Somatic: Regular body cells (e.g., skin, muscle, bone)
- Prophase: Early stage of mitosis/meiosis
- Metaphase: Chromosomes line up in the middle
- Anaphase: Sister chromatids separate
- Telophase: Chromosomes decondense
- Spindle Fibers: Structure that separates chromosomes
- Budding: A form of asexual reproduction
- Spores: A form of asexual reproduction
- Vegetative Propagation: New plant growing from a piece of the original
- Cancer: Cell cycle timing issues
- Chromatid: One of two identical copies of a chromosome
- Differentiation: Specialising/changing of cells
- Daughter Cells: Cells formed from a parent cell
- Benign: Non-cancerous tumor
- Malignant: Cancerous tumor
- Tumor: Abnormal growth of cells
- Karyotype: Visual representation of chromosomes
- Centriole: Organelle used in cell division
- Nondisjunction: Failure of chromosomes to separate
- Stem Cell: Undifferentiated cells that can develop into other cell types
