Document Summary
Free living (single cell individuals) which are yeasts. Filamentous: body is comprised of long strands called hyphae. These hyphae are long chains of cell like structures that are joined end to end and the cells are divided by cross pieces called septa. Septa aren"t complete barriers and usually have pores that allow the free flow of cytoplasm. Coenocytic fungi: fungi that don"t have septa separating their cells. Cell separation isn"t important to fungus and free flow is an important trait because products that are absorbed by the fungus, can quickly stream throughout the body. This allows fungus to grow rapidly when resources are abundant. Mycelium: when you join a bunch of hyphae together. External digestion (absorptive heterotrophy)- fungus secretes digestive enzymes and the fungus absorbs those nutrients. Yeast has the largest surface area so they can maximize the amount of nutrients that they can absorb. Nutrients must be dissolved in water to be absorbed so they are dependent on water.
