1. Asexual vs. Sexual External vs. Internal Fertilization Spores vs. Seeds in Plants Egg Types

2. AsexualSexual More opportunitiesLess opportunities Less energy neededMore energy needed More offspringLess offspring No parental careSome parental care Lower offspring survivalHigher offspring survival

3. Asexual Reproduction

5. External(outside)Internal(inside) Needs a water environmentDoesn’t require a water environment Eggs are unprotectedEggs are protected (uterus or shell) Random/inaccurate fertilization Specific/accurate fertilization Large amounts of sperm/eggSmall amounts of sperm/egg Typically aquatic animals (fish, amphibians) Typically land animals (reptiles, birds, mammals)

6. SporesSeeds Microscopic sizeLarge and visible Simple single-celled structureComplex multi-celled structure Produced by leavesProduced by flowers/fruit Needs water to germinateCan germinate anywhere Spread by windSpread by animals, wind, & water Produced in large amountsProduced in lesser amounts

10. Fish & Amphibian Eggs -no shell -embryonic sac provides nutrients -needs water to survive Amniotic Egg -yolk sac provides nutrients -shell protects embryo -Reptiles(soft) & Birds(hard) - survives dry land

11. Placental Mammals -no shell -placenta provides nutrients -internal development
