Asexual reproduction

Regeneration

Development of an organism from part of the parent organism or replacement of lost body parts Examples: planaria, starfish, sponge, lobster

Types of asexual reproduction

Fission, budding, sporulation, regeneration

Binary fission "equal division"

Parent organism divides into two equal sized daughter cells Simple Equal cytoplasmic division Examples: amoeba, paramecium, bacteria

Budding "unequal division"

Parent organisms divide into two unequal cells Daughter (bud) is smaller than parent cell Unequal cytoplasmic division Examples: yeast, hydra

Sporulation "many at one time"

Produces many tiny daughters (spores) Contains a nucleus and small amount of cytoplasm Surrounded by a thick, hard, outer wall Examples: bread molds, mushroom, mosses, ferns,

Asexual reproduction (PMAT)

Production of offspring with one parent cell Involves mitosis Offspring are genetically identical to parent

Sexual reproduction

Recombination, gameteiosis, spermatogenesis, cutting

Vegetative propagation (asexual reproduction in plants)

Using roots, stems, or leaves to produce new plants; new plant same as parent Try to reproduce plants with desirable traits Larger, sweeter fruit Distinctive coloration Advantages: seeds not necessary, large number of offspring are produced rapidly Disadvantages: lack of variation
