Asexual vs. Sexual Reproduction 1 Match it Up- From your prior knowledge, match up the two types of reproduction with their characteristics and place the items a the Venn Diagram in your interactive notebook Reproduction Type Characteristics Two parents Identical offspring Sexual reproduction One parent Not identical offspring Passes on DNA to from parent to Asexual reproduction offspring Bacteria, protists, some plants, yeast Fish, Mammals, Amphibians, Birds, Reptiles, Insects 2 Make a Venn Diagram Asexual Sexual Reproduction Reproduction Both Types of reproducti on in living organisms Pass DNA from parent to offspring 3 Picture Play Look at each picture and decide whether it demonstrated asexual or sexual reproduction and describe why you think so. 4 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. Mitosis Movie 5 Asexual Reproduction Binary Fission Bacteria Protists Binary fission is a form of asexual reproduction where every organelle is copied and the organism divides in two. 6  Asexual Reproduction Budding Hydra  Movie Budding is a means of asexual reproduction whereby a new individual develops from an outgrowth of a parent, splits off, and lives independently. 7 Asexual Reproduction- Spore Found in fungi, algae, protozoa Airborne cells that are released from the parent. They are enclosed and developed when the environment is appropriate 8 Asexual Reproduction Regeneration Regeneration occurs when a body part has broken off and the organism grows a new one. 9 Asexual Reproduction Fragmentation Fragmentation is a means of asexual reproduction whereby a single parent breaks into parts that regenerate into whole new individuals. 10 Asexual Reproduction  Plant cuttings/ vegetative propagation Vegetative reproduction is a type of asexual reproduction in plants that relies on multi-cellular structures formed by the parent plant. It has long been exploited in horticulture and agriculture, with various methods employed to multiply stocks of plants. 11 Asexual reproduction- Mitosis The process where animal cells divide This is a type of asexual reproduction Body cells (somatic cells) go through the process of mitosis Results in an exact copy of the parent cell 12 Asexual Reproduction Examples of organisms that reproduce asexually Hydra Sea Star Strawberry Archaebacteria Eubacteria Euglena Paramecium Yeast 13 Mitosis Brain Pop http://glencoe.mcgraw-hill.com/sites/dl/fr ee/0078768349/164155/00053413.html 14 Sexual Reproduction All the members of the Animal Kingdom Fish Mammals Amphibians Birds Reptiles Insects Crustaceans 15 Sexual Reproduction Requires two parents that each share ½ of the genetic information. Offspring share the characteristics of each parent. Meiosis 16 Advantages vs Disadvantages of Asexual Reproduction Advantages Disadvantages  Asexual reproduction  Same DNA being passed produces more offspring down NO GENETIC  Asexual reproduction VARIATION IN THE takes less time OFFSPRING  Only one parent  If parent has genetic involved. No searching disease offspring will for mates have it too  Requires less energy 17 Advantages vs Disadvantages of Sexual Reproduction Advantages Disadvantages  Variation in offspring  Requires two organisms.  Organism is more Must find a mate protected because of  requires more cellular genetic variation energy  More time required for offspring development 18 Sexual Reproduction Plant Kingdom Flowers are the reproductive organs of plants. Male Female Some flowers flower have both male and female flower reproductive organs on the same flower. 19 Sexual Reproduction Examples of organisms that reproduce sexually Chickens Iguanas Lobsters Sharks Humans Butterflies Sunflowers Roses 20 Sexual Reproduction Happens 2 ways Internally (inside)  The egg is fertilized by sperm inside the female  Mammals, birds, reptiles, insects, spiders Externally (outside)  The egg is fertilized by sperm outside the female  The female lays the eggs and then the male fertilizes them.  Fish and some amphibians  Plants and fungi (pollen and spores) 21 Summarize Write two paragraphs with 6 sentences each describing asexual and sexual reproduction. Paragraph 1: Asexual reproduction is….. Paragraph 2: Sexual reproduction is… 22
