Study Notes
- Meiosis is a type of cell division that occurs in sex cells or gametes
- Meiosis consists of two rounds of cell division, labeled I and II
- Crossing over process, a crucial genetic recombination event, takes place exclusively during prophase I of meiosis
- Meiosis results in the production of four haploid daughter cells
- Parent cell undergoes meiosis and transforms from a diploid to a diploid state before producing haploid daughter cells
- Somatic or body cells are diploid, carrying 46 chromosomes
- Gametes or sex cells are haploid, carrying 23 chromosomes
- Somatic cells undergo mitosis for growth and repair, dividing once
- Microscopes are instrumental tools used to magnify objects that are too small to be seen by the naked eye
- Micrographs are photographs taken using a microscope
- A microscope consists of various parts including: eye piece, body tube, coarse adjustment knob, fine adjustment knob, objective, fine adjustment knob, condenser, inclination joint, mirror base, and scanning objective lens (L4, LPO, HPO, oil immersion)
Test your knowledge on the key differences between meiosis and mitosis, including the number of cell divisions, occurrence of crossing over, and resulting daughter cells. Understand the ploidy count changes and chromosome behavior during both processes.
