Study Notes
Protein Functions
- Maintain cell shape and internal structure
- Produce molecules and eliminate waste
- Conduct routine repairs and maintenance
Metaphase
- Chromosomes align at the cell's center (metaphase plate)
- Spindle fibers connect to chromosomes and centrioles
Chloroplast Function
- Facilitates photosynthesis, producing energy and oxygen
Vacuole Function
- Degrades and removes cellular waste
Mitosis vs. Meiosis (Differences)
- Mitosis: one stage, produces two identical daughter cells (diploid)
- Meiosis: two stages, produces four genetically diverse daughter cells (haploid)
Nucleolus Function
- Synthesizes and assembles the cell's ribosomes
Interphase Stages
- G1: Cell growth and enzyme production
- S: DNA replication
- G2: DNA error checking and organelle creation
Golgi Apparatus Function
- Packages proteins and lipids
Anaphase
- Sister chromatids separate at the centromere
- Spindle fibers pull chromosomes to opposite poles
- Each daughter cell receives an identical chromosome set
Telophase
- Nuclear envelopes form around each chromosome set
- Spindle fibers break down
- Chromosomes unwind
Interphase Events
- Nucleus prepares for division
- Double-stranded DNA packages into chromosomes
- DNA replicates into two identical copies
Prophase
- Nuclear envelope breaks down
- DNA condenses forming chromosomes
- Mitotic spindle develops
Cytokinesis
- Cell membrane pinches, creating two daughter cells
- Cytoplasm and organelles split between the two cells
Plasma Membrane Function
- Controls movement of substances in and out of the cell
