Study Notes
Cell Division Process
- Cells undergo division to create two new daughter cells, ensuring the continuation of life.
DNA and Cell Size
- Larger cells increasingly rely on their DNA, which can limit their size due to slower information processing.
Key Cell Terms Defined
- Cell Volume: The space occupied within the cell.
- Cell Surface Area: The total area of the cell membrane that interacts with the environment.
- Surface Area to Volume Ratio: A ratio crucial for understanding cell efficiency; as volume increases, surface area may not keep pace.
Growth Potential and Surface Area Ratio
- The ratio of surface area to volume decreases as a cell grows, potentially leading to issues in nutrient uptake and waste elimination.
Chromosome Changes in Division
- Prior to division, each chromosome replicates, resulting in two identical sister chromatids, ready to be divided during the process.
Interphase and Cell Division Link
- Interphase is vital for cell growth and preparation and occurs between each division cycle, not part of the actual splitting process.
Events of Interphase
- During interphase, cells grow, synthesize proteins, replicate chromosomes, and produce necessary organelles for division.
Relationship of Genetic Structures
- DNA: The genetic material of an organism.
- Chromosomes: Condensed structures of DNA within the nucleus.
- Chromatids: Identical halves of a replicated chromosome.
- Centromeres: The central region of a chromosome that separates chromatids during mitosis.
Sequence of Mitosis Events
- Prophase: Chromosomes condense and centrioles move to opposite poles.
- Metaphase: Chromosomes align at the cell's equatorial plane.
- Anaphase: Sister chromatids separate and travel to opposite ends.
- Telophase: Chromosomes unwind back into chromatin and the nuclear envelope begins to reform.
Chromosome Consistency Post-Division
- Each daughter cell retains the same number of chromosomes as the original cell, ensuring genetic continuity.
Overview of the Cell Cycle
- The cell cycle consists of growth (G1), DNA synthesis (S), preparation for mitosis (G2), and division (M), culminating in two new daughter cells that re-enter the cycle.
