1. Chapter 3.3 Pages 88 - 92

2. 1. unicellular organisms 2. offspring’s genes are identical to parent’s 3. multicellular organisms 4. daughter cells – not new offspring Cell Division in Unicellular Organisms 1. prokaryotes 2. unicellular eukaryotes 3. binary fission 4. budding 5. algae, yeasts & protozoa

3. binary fission daughter cells

4. Yeast is the only unicellular fungus

5. Budding 1. outgrowths of a parent organism 2. genetically identical 3. advantage is many offspring 4. disadvantage is no genetic diversity Regeneration 1. multicellular organisms 2. healing; missing body parts 3. sea stars, many plants

6. Asexual Reproduction and Health 1. bacteria and illness 2. binary fission every 20-30 minutes 3. “strep” throat – Streptococcal pharyngitis

7. 1. genes from two parents combine 2. results in a “new” organism of same species 3. “diversity” 4. usually takes more time than asexual reproduction 5. often uses sperm and egg

8. asexual reproduction - the process by which a single organism produces offspring that have the same genetic material binary fission - a form of asexual reproduction when a parent organism replicates its DNA and splits into two new offspring regeneration - in some organisms, the process by which certain cells produce new tissue growth at the site of wound or lost limb, also a form of asexual reproduction
