  1. Asexual Reproduction

  2. Asexual Reproduction • Requires only one parent • Offspring have 100% the same chromosomes as the parent. • In other words, the offspring are exact “clones” of the parent. • Most unicellular organisms reproduce this way.

  3. Binary Fission • Binary fission is a form of asexual reproduction where every organelle is copied and the organism divides in two. Ex: - Bacteria - Protists

  4. Budding • Budding is a means of asexual reproduction whereby a new individual develops from an outgrowth of a parent, splits off, and lives independently. • Ex: - Yeast

  5. Fragmentation Fragmentation is a means of asexual reproduction whereby a single parent breaks into parts that regenerate into whole new individuals. Ex: - Starfish

  6. Spores Organism undergoes frequent cell division to produce many smaller identical cells called spores. Ex: - Dandelions - Mold

  7. Regeneration Regeneration occurs when a body part has broken off and the organism grows a new one.

  8. A Few Questions to Think About 1. How is asexual reproduction different from sexual reproduction? 2. How is the zygote, produced by sexual reproduction, different from daughter cells, produced by asexual reproduction? * Remember a zygote is a fertilized egg.
