Advantages of Asexual reproduction
Only one parent needed, reproduction occurs quickly, offspring mature quickly, offspring genetically identical so if conditions remain the same, offspring are likely to survive
Disadvantages of asexual reproduction
Lack of genetic variation, vulnerabilities to environmental changes, potential accumulation of harmful mutations
Advantages of sexual reproduction
Genetic diversity, allows some individuals to survive if conditions changes
Disadvantages of sexual reproduction
searching for a mate takes time and exposes organisms to risks, fewer offspring produced, offspring take longer to mature and reproduce, offspring require a lot of time and energy to raise to become independent from their parents
Another name for sex cells
gametes
Male sex cells
Sperm, located in testes, small in size
Female sex cells
Eggs, located in ovaries, larger in size
Fertilized egg
Zygote that results from the fusion of a sperm and an egg’s nuclei, carries genetic information from both parents
Mammal reproduction
Development of fertilized egg to offspring occurs inside the female (e.g womb), female is the source of offspring’s nourishments
Insects
Sexually, some insects (e.g bee) don’t need fertilization, unfertilized eggs becomes males, fertilized eggs become females
Fish, Frog, and Birds
Fertilized eggs develop outside the female’s body, offspring are released when eggs hatch
Plants
Most plants have male and female reproductive parts (hermaphrodites), the sperm is the pollen, the egg is inside the plant, pollen is transferred by the and or animals
