Flashcards
Spermiogenesis
Spermiogenesis
The final stage of sperm development where spermatids transform into mature sperm cells.
What is released during ovulation?
What is released during ovulation?
The secondary oocyte, which is a haploid cell, is released from the ovary during ovulation.
Organelles in a fertilized ovum
Organelles in a fertilized ovum
The fertilized ovum, or zygote, inherits most of its organelles from the maternal egg, except for the double-membranous organelles like mitochondria, which come from the father.

Study Notes
Cell Cycle and Cell Division
- Question 3: The earliest phase where chromosomes are composed of two identical copies held together at the centromere is the S phase.
Organelle Origin
- Question 17: Organelles are mostly maternally inherited, except for those with a double membrane.
Cell Cycle Exit
- Question 13: A cell exits the cell cycle in the G0 phase.
Ovulation
- Question 16: The cell released from the ovaries during ovulation is the secondary oocyte.
Homologous Chromosome Pairing
- Question 10: Homologous chromosome pairing occurs during prophase I.
Chromosomes in Female Stomach Cells
- Question 9: Stomach cells in females have 22 pairs of chromosomes plus two X chromosomes.
Mitotic Spindle Attachment
- Question 18: Sister chromatids attach to the mitotic spindle during prometaphase.
Spermatogenesis
- Question 19: Spermatogonia undergo mitosis to form primary spermatocytes.
Somatic Cell Cytokinesis Failure
- Question 5: A somatic cell that fails cytokinesis will result in a large multinucleated cell.
Centriole Duplication
- Question 14: Centrioles duplicate during interkinesis without chromosomes duplicating.
Crossing-Over
- Question 20: Crossing-over and reciprocal DNA exchange between chromatids create recombinant chromatids.
Chiasmata in Primary Oocytes
- Question 2: Non-sister chromatids of a homologous pair are held together at chiasmata in a primary oocyte.
Metabolically Active Cell Cycle Stage
