Abdomen : Houses functional system. Digestive and in females the reproductive systems. Albumen : Surrounding the whole structure (amnion), protein source. When it’s broken down it produces metabolic water. Water source for the embryo as well. Allantois : As protein breaks down nitrogen (nitrogenous waste, ammonia) will shut down the embryo. All the nitrogenous waste is kept in the allantois. Structure that houses the metabolic waste. Ametabolous metamorphosis : No metamorphosis occurs in the group. Wingless group. Divides the habitat up between the young and adult stages. Amnion sac : The aquatic environment in which the embryo can live and undergo it’s development. The mini marine environment for the embryo. Shell surrounds it that is optimized for gas exchange but minimized for water loss. Amniotes : Base of the evolutionary tree of the vertebrates to come. The reptiles (birds) and mammals to come. Called amniotes because a new type of egg. Amphibia : Special fish with enough structure in the fins to move up on land. Took advantage of the HUGE food source was the insects. Unique feed strategy of shooting out the tongue to grab the food. Skin is still a respiratory surface, with many glands to keep it moist. No protective armor, but poison glands. Still have to lay eggs in the water. Pelvic/pectoral limbs still attach at the side, not underneath. Arbuscular mycorrhizal fungi : Plant allow the fungi to send in mycelia and invade plant cells. Internalized fungus to ensure gets action to the minerals. Essential to growth of plants. Archegonium : Female housing of the megaspore. Arthropod : Ecdysozoa that have the insects that dominate the carboniferous era. Mainly the insects. Scorpion-like arthropods have come up to the terrestrial environment as well. Ascocarp : The reproductive body that contains the ascus. Ascomycota : Cup-shaped fungi. Spores in structures called asci. Similar life-cycle to the basidyomycota. 8 spores. Dikaryotic structures to extract nutrients and materials from the environment. Ascus : Where the spores are housed. Spores are housed in these. Meiosis here give rise to 8 spores. Background extinction : Losses due to certain events that are the “noise” on the extinction scales. Things are always being lost and replaced. Under 50%. Basidium : The meiotic products hanging from the mushroom gills (from karyogamy), there should be 4. Used to identify mushroom types. They are the spores of the mushroom. Basidyomycota : Mushrooms. Spends a large part of the life cycle in dikaryotic life cycle. Mushrooms that we each are the dikaryotic mycelia. Fruit body is tightly woven mycelia. Water is pumped (using extra surface area) to the fruit body to help it grow quickly. 4 spores. Carboniferous period
