1. What are hyphae?
Hyphae are the long, branching filamentous structures that make up the mycelium of a fungus. They are the main mode of vegetative growth and absorb nutrients from the environment.
2. Describe the mode of hyphal growth.
Hyphal growth occurs at the tip (apex) of the hypha. New cell wall material and cytoplasm are added to the growing tip, allowing the hypha to extend forward into new areas for nutrient absorption.
3. What is a septum? What is its function?
A septum is a cross-wall that divides the hypha into individual cells. Its primary function is to compartmentalize the hypha, which can help contain damage or infection and regulate the flow of cytoplasm and organelles between cells.
4. What are coenocytic fungi, and why are they important?
Coenocytic fungi are those whose hyphae lack septa, resulting in long, continuous tubes containing many nuclei. They are important because their multinucleate structure allows for rapid growth and efficient distribution of resources throughout the hypha.
5. How do fungi use hyphae to obtain nutrients?
Fungi secrete digestive enzymes into their surroundings through their hyphae. These enzymes break down complex organic matter (like cellulose or lignin) into simpler molecules, which are then absorbed directly through the hyphal walls into the fungal cells.
