Study Notes
Characteristics of Fungi
- Fungi were originally classified as plants but are now classified in a separate kingdom.
- Fungi do not make their own food, unlike plants, and do not contain chlorophyll.
- Fungi feed on dead or decaying tissues.
- Fungi range in form from single-celled yeast to multicellular organisms like the honey mushroom.
- Fungi grow best in warm, humid areas.
Fungi Structures
- Fungi are made up of thread-like filaments called hyphae, which form a mass of threads called a mycelium.
- The mycelium grows throughout the source of food and releases digestive enzymes.
- The enzymes break down large compounds into smaller substances that can be absorbed into the cells of the fungus.
How Fungi Get Their Food
- Fungi absorb nutrients from their surroundings using hyphae.
- Fungi release digestive enzymes into their surroundings, breaking down organic material.
- Fungi absorb the nutrients directly into their cells.
- Some fungi digest the dead remains of other organisms.
- Others are parasites that live on plants or animals, causing them harm.
Types of Nutrition
Autotrophic Nutrition
- Autotrophs synthesize organic materials from inorganic materials.
- Most plants are autotrophs, producing their own nutrition through photosynthesis.
Heterotrophic Nutrition
- Heterotrophs obtain energy by ingesting or absorbing organic food.
- Saprophytic nutrition: saprophytes (decomposers) break down complex organic matter from dead organisms, releasing chemical elements into the soil.
- Parasitic nutrition: parasites live in or on other living organisms, receiving shelter and deriving nutrients from them, often causing harm to the host.
