Sivani Shared "Chapter 2 - Reproduction" - 9 Picmonics
With Picmonic, facts become pictures. We've taken what the science shows - image mnemonics work - but we've boosted the effectiveness by building and associating memorable characters, interesting audio stories, and built-in quizzing. Whether you're studying for your classes or getting ready for a big exam, we're here to help.

3 mins
Prophase
- Nuclear Membrane Disintegrates
- Centrioles Migrate
- Spindle Apparatus Forms
- Meiosis I starts Diploid
- Homologous Chromosomes form Tetrads
- Tetrads Cross Over
- Meiosis II starts Haploid
- Mitosis starts Diploid
- Sister Chromatid Pairs Stay Separated
2 mins
Metaphase
- Characteristics
- Microtubules Extend from Centrioles' Spindles
- Centromere
- Kinetochore
- Meiosis I Tetrads Aligned at Metaphase Plate
- Meiosis II Sister Chromatids Aligned at Metaphase Plate
- Mitosis Sister Chromatids Aligned at Metaphase Plate
57 secs
Anaphase
- Spindle Microtubules from Centrioles Split Pairs
- Meiosis I Tetrad Splits into Two Sister Chromatid Pairs
- Meiosis II Sister Chromatid Pair Splits into Two Chromatids
- Mitosis Sister Chromatid Pair Splits into Two Chromatids

Telophase
- Cytokinesis Divides Cells
- Meiosis I Cell Ends Haploid
- Meiosis II Cell Ends Haploid
- Mitosis Cell Ends Diploid
- Chromosomes Decondense into Chromatin
- Nuclear Membrane Reforms

Oogenesis
- Characteristics
- Primary Oocytes From Birth
- Meiosis I Once a Month
- Secondary Oocyte Plus Polar Body
- Frozen in Metaphase II, in Meiosis II
- Ovulation
- Fertilization by Sperm
- Meiosis II
- Ovum
- Zygote Forms
2 mins
Spermatogenesis
- Seminiferous Tubules
- Sertoli Cells
- Spermatogonia
- Mitosis
- Primary Spermatocyte
- Meiosis I
- Secondary Spermatocyte
- Meiosis II
- Spermatid
- Spermatozoa

Ovulatory Hormones I - Follicular Phase
- Characteristics
- 0-14 Days
- GnRH Stimulates FSH and LH
- Follicle Secretes Estrogen
- Negative Feedback from Estrogen
- Increased Estrogen Leads to Positive Feedback
- FSH and LH Surge
- LH Spike Leads to Ovulation
2 mins
Ovulatory Hormones II - Luteal Phase
- Days 15-28
- Corpus Luteum
- Secretes Progesterone
- Negative Feedback inhibits FSH and LH
- No pregnancy forms Corpus Albicans
- Stops Estrogen Secretion
- Endometrial Sloughing - Menses
- GnRH secretion produces new follicular phase
