Mycorrhizae Study guides, Class notes & Summaries

3 ways cowbirds find hosts - 1. sit high on perch and look around 2. walk on ground and look 3. drive birds off by scaring them so that they can lay their eggs 4 advantages of seed dispersal - -Avoids crowding competition -Prevents spread of disease -Prevents in-breeding -Saves some offspring from being eaten 5 adaptations of obligate brood parasites - 1. fast egg laying (20-40 sec for cowbirds) 2. thicker egg shells 3. fast hatching egg 4. removal of host egg prior to laying 5. baby ...

Monocot root system - Answer-Fibrous Eudicot root system - Answer-Taproot Mycorrhizae - Answer-Symbiotic relationship between plants and fungi (hyphae) - increase in surface area Nodes - Answer-Portion(s) of the stem where leaves attach Internodes - Answer-Segments of the stem where no leaves attach Terminal buds - Answer-Composed of developing leaves and are partly responsible for inhibiting the growth of axillary buds by apical dominance. Apical dominance - Answer-Plants grow verticall...

1. In most fungi, karyogamy does not immediately follow plasmogamy, which consequently A) means that sexual reproduction cannot occur. B) decreases the overall size of the organism. C) allows fungi withstand harsh conditions in a dormant state. D) results in heterokaryotic or dikaryotic cells. - Answer-D) results in heterokaryotic or dikaryotic cells. 2. Which of the following best describes the physical relationship of the partners involved in lichens? A) Fungal cells are enclosed within ...

charophytes - (aquatic) green algae land plants evolved from 3 key traits land plants share with charophytes - 1. rings of cellulose-synthesizing proteins embedded in plasma membrane 2. formation of a phragmoplast (helps form cell wall) 3. structure of flagellated sperm (not all will have this) adaptations enabling plants' move to land: why? - 1. CO2 2. sunlight 3. soil- nutrients 4. fewer predators/pathogens (never been seen before) adaptations enabling plants' move to land: problems...
