MITOSIS vs. MEIOSIS

1. MITOSIS vs. MEIOSIS Regular vs. Reduction Division in Eukaryotic Cells

2. Produces new somatic cells which will mature and become specialized in plant tissues and organs MITOSIS vs. MEIOSIS

3. Produces new somatic cells which will mature and become specialized in plant tissues and organs Produces cells destined to become reproductive cells MITOSIS vs. MEIOSIS

4. Produces new somatic cells which will mature and specialize into plant structures Identical cell duplication Produces cells destined to become reproductive cells MITOSIS vs. MEIOSIS

5. Produces new somatic cells which will mature and specialize into plant structures Identical cell duplication Produces cells destined to become reproductive cells Reduction division MITOSIS vs. MEIOSIS

6. Produces new somatic cells which will mature and specialize into plant structures Identical cell duplication Diploid Diploid Produces cells destined to become reproductive cells Reduction division MITOSIS vs. MEIOSIS

7. Produces new somatic cells which will mature and specialize into plant structures Identical cell duplication Diploid Diploid Produces cells destined to become reproductive cells Reduction division Diploid Haploid MITOSIS vs. MEIOSIS

8. Produces new somatic cells which will mature and specialize into plant structures Identical cell duplication Diploid Diploid One cell division cycle Produces cells destined to become reproductive cells Reduction division Diploid Haploid MITOSIS vs. MEIOSIS

9. Produces new somatic cells which will mature and specialize into plant structures Identical cell duplication Diploid Diploid One cell division cycle Produces cells destined to become reproductive cells Reduction division Diploid Haploid Two cell division cycles MITOSIS vs. MEIOSIS

10. One, 2n cell Two, 2n daughter cells MITOSIS vs. MEIOSIS

11. One, 2n cell Two, 2n daughter cells One, 2n cell Four, n meiospores MITOSIS vs. MEIOSIS

12. One 2n cell Two 2n daughter cells Daughter cells identical (virtually clones of each other) One 2n cell Four n meiospores MITOSIS vs. MEIOSIS

13. One 2n cell Two 2n daughter cells Daughter cells identical (virtually clones of each other) One 2n cell Four n meiospores Meiospores carry only part of the original genome which has been basically “shuffled” among the four cells MITOSIS vs. MEIOSIS
