Asexual and Sexual Reproduction
Asexual reproduction: a single parent passes on all its genetic material to each of its offspring
Sexual reproduction: two parents form gametes that each contribute half the genetic material to the new offspring; sex cells have half the number of chromosomes
Both:Produce offspring and offspring have genetic material of parents
Reproduction

Benefits
Asexual reproduction: fast
Sexual reproduction:genetic variation
Methods of Asexual Reproduction
Binary FissionBuddingVegetativeMitosis and Cell Division
Reproduction
3
Binary Fission:Used in prokaryotesProduces identical offspringTwo steps 1.DNA is copied 2.New cell membrane divides cell
Examples:bacteria, amoeba, paramecium
Budding:New individual splits off from original parentParent remains
Examples:yeasts, sponges, hydra
Reproduction

Vegetative (propagation):plants produce new individuals from various plant parts without seeds
Examples:Seed Plants
Mitosis:a mother cell produces two daughter cells (identical)
for growth and replacement of damaged cells
Examples:all organisms
