Asexual vs. Sexual Reproduction Grade 8 - Biology At the end of the topic the students will be able to… ◼ Define asexual reproduction ◼ Define sexual reproduction ◼ Define asexual reproduction ◼ Describe the differences between sexual and asexual reproduction I will… ◼ Read and study PowerPoint & Video ◼ Complete a Venn Diagram (asexual reproduction and sexual reproduction) ◼ Illustrate (draw pictures) fertilization, budding, sexual reproduction, and asexual reproduction (be careful!!!) ◼ Explain and describe fertilization, budding, asexual reproduction, and sexual reproduction (working with a partner/small group) ◼ Write a paragraph (at least 5 sentences) explaining how offspring from sexual reproduction have more genetic differences than offspring from asexual reproduction Sexual Reproduction ◼ Sexual ◼ 1. 2 parents Reproduction ◼ 2. Sex cells: sperm and egg ◼ 3. Sperm and egg join= fertilization ◼ 4. Offspring look different from parent (mixed DNA) Sexual Reproduction ◼ Sexual ◼ 5. Examples Reproduction – Humans, some plants, mammals, fish, reptiles, etc. Sexual Reproduction Fertilization: part of the process of sexual reproduction in which a male reproductive cell and a female reproductive cell combine to form a new cell that can develop into a new organism. Asexual Reproduction ◼ Asexual ◼ 1. One parent Reproduction ◼ 2. No sex cells ◼ 3. Offspring produced by cell division ◼ 4. Offspring identical to parent (same DNA) ◼ 5. Several types in plants and animals Types of Asexual Reproduction ◼ Binary ◼ 1. Organism divides in half Fission ◼ 2. 2 identical daughter cells produced ◼ 3. Daughter cells are half the parent’s size ◼ 4. Daughter cells grow, then divide too ◼ 5. In bacteria Types of Asexual Reproduction ◼ Budding ◼ 1. Small bud grows out of parent cell ◼ 2. Two different sized cells made (with identical DNA) ◼ 3. Bud breaks off and grows ◼ 4. In yeast and hydra Types of Asexual Reproduction ◼ Regeneration ◼ 1. Repair/ grow lost body parts ◼ 2. Left over cells divide to make more cells ◼ 3. Lobsters, starfish, lizards What type of reproduction is this??? Explain… What type of reproduction is this???
