The Primary role of Fungi - correct answer-Decomposers- they break things down Modes of Nutrition in Fungi - correct answer-Heterotrophs with extracellular digestion Exoenzymes - correct answer-Fungi Release these enzymes outside of the cell wall. Break down complex molecules into smaller organic molecules which can be absorbed. Extracellular Digestion - correct answer-The release of exoenzymes out side of the cell wall, followed by the absorption of nutrients.. Saprobes - correct an...

How do fungi use absorptive heterotrophy? Correct Answer-Fungi secrete hydrolytic enzymes into their surrounds that break down complex molecules to smaller organic compounds that the fungi can absorb into their bodies and use. Other types of fungi use enzymes to penetrate the walls of cells, enabling the fungi to absorb nutrients from the cells. What are hyphae? Correct Answer-Multicellular fungi typically form a network of tiny filaments called hyphae. Hyphae consist of tubular cell walls su...

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 ...

Although fungi generally lack extensive cellular specialization, what feature of hyphal growth makes them so well suited as decomposers, mutualistic symbionts, and pathogens? correct answer: a large surface area Fungi have unique life cycles. A fungus that has two parental nuclei in one cell is referred to as a ___________. correct answer: dikaryon dikaryon correct answer: hyphae with cells having 2 different nuclei in each cell.
