Asexual vs. Sexual Reproduction

Asexual reproduction Mitosis – Muti-cellular organisms Binary Fission – Single celled organisms Asexual reproduction = one parent. Both original and new cells contain identical DNA

Sexual Reproduction Sexual DNA from 2 individuals merge to form one Cells created by MEIOSIS + Diverse DNA

Binary Fission Asexual Prokaryotes, Bacteria + Fast and easy - Everybody has the same DNA

Budding Asexual Offspring grows out of parent Yeast, hydras - Same DNA

Fragmentation/ regeneration Asexual Body of parent breaks and produces offspring Fungi, moss, sea stars, planarian - Parent broken, same DNA

Fragmentation/ regeneration Moss

Bacterial Conjugation “Sexual” A bacteria shoots out a tube and sends a piece of its DNA to another bacteria Bacteria + Mixes DNA - “Parent” loses a little piece of DNA

Pollination Sexual Pollen is delivered to female part of plant Flowering plants + Plants don’t have to move, mixes DNA - Need external source for pollination to take place; wind, bee, bat, butterfly etc.
