Study Notes
Embryology
- Embryology is the study of early living organism development
- All animals and plants can reproduce to ensure survival of their kind
Reproduction
- Asexual reproduction
- One parent splits, buds, or fragments to create two or more new organisms
- Examples include: splitting (Paramecium), budding (Hydra), fragmentation (yeast)
- Sexual reproduction
- Two gametes (sperm and egg) fuse to form a zygote
- Male gamete (sperm) fuses with female gamete (egg)
- The zygote develops into an embryo via embryonic development stages
Asexual Reproduction: Types
- Splitting: The organism splits into two individuals (e.g., Paramecium)
- Budding: The organism produces a small bud that grows on the parent's body and then detaches (e.g., Hydra)
- Fragmentation: The organism fragments into pieces, each of which develops into a new organism (e.g., yeast)
Sexual Reproduction
- Fusion of male and female gametes (sperm and ovum) to form a zygote
- Sperm's chromosomes (n) join with ovum's chromosomes (n) forming the zygote's chromosomes (2n)
- Zygote undergoes embryonic development, dividing into many somatic cells (2n) that form the embryo
Gametogenesis
- Production of gametes (sperm and egg) by parents
- Reduction in chromosome number from diploid (2n) to haploid (n) in the resulting gametes
- Gametogenesis in testis (spermatogenesis): a series of steps
- The steps: Multiplication, Growth, and Maturation phases
- Results in the production of four sperms from one primary spermatocyte
- Gametogenesis in ovary (oogenesis): a process
- The steps: Multiplication, Growth, and Maturation phases
- Results in one ovum (egg) from one primary oocyte
Spermatozoon
- Structure: Head, midpiece (body), principal piece, and tail
- Different types of shapes (spherical, Y-shaped, spiral, spoon-shaped) exist depending on the organism, e.g., Chordates, Amphibia, Reptiles, and Mammals.
