LIFESCI 2 Chapter Notes - Chapter 34: Mycelium, Plant Cell, Critical Role
Document Summary
Solution: they secrete many enzymes that break down the complex molecules into simple ones: 2. ) hard to find food in environment bc cannot move. Solution: process of growth to find nourishment. Hyphae = allows fungi to explore environment for food. Slender & provide large surface area for absorbing nutrients. Growth of these slow down if resources are slow. Growth is really fast if there are lots of food and then hyphae end up forming a network called mycelium or mycelia: fungi transport materials within hyphae. Strong & flexible cell way = key to hyphal growth: result: can grow between resource patches and produce reproductive structures such as mushrooms that rise above ground, not all fungi produce hyphae, ex. ) Ectomycorrhizal fungi hyphae do not penetrate root cells, only surround it: 2. ) Endophytic hyphae grow within cell walls & in spaces between cells: may help host plant by producing chemicals that deter pathogens & insects.
