Study Notes
Reproduction
- Living organisms use various mechanisms to perpetuate their species, including sexual and asexual modes of reproduction.
Sexual Reproduction
- Involves the fusion of gametes from two parents, resulting in genetic variation among offspring.
- Enhances adaptability to changing environments due to genetic variation.
- Occurs in both plants and animals, with diverse reproductive structures and processes.
Asexual Reproduction
- Involves the production of offspring from a single parent.
- Often results in genetically identical progeny.
- Employed by different species to ensure the continuation of their lineage.
Reproductive Health
- Importance of reproductive hygiene to prevent infections.
- Contraception methods to prevent unwanted pregnancies.
- Prevention and treatment of sexually transmitted infections (STIs).
