Study Notes
Differences Between Fungi and Plants
- Fungi structure consists of hyphae, while plants have a different cellular structure.
- The sugar found in fungi is chitin, contrasting with the cellulose in plants.
- Fungi are heterotrophic, meaning they obtain nutrients by consuming other organisms, unlike autotrophic plants.
Eukaryotic Nature of Fungi
- Fungi are classified as eukaryotic organisms due to the presence of a nucleus and membrane-bound organelles within their cells.
Parasitic Fungi
- Parasitic fungi derive nutrients from a living host, potentially harming the host organism.
- Examples include potato blight and athlete's foot.
Saprophytic Fungi
- Saprophytic fungi feed on decomposing organic matter, playing an essential role in nutrient cycling.
- Common examples include Rhizopus (black bread mold) and yeast.
Economic Impacts of Fungi
- Negative economic effects include food spoilage, disease in crops, and timber rot.
- Positive contributions involve the production of alcohol, bread, antibiotics, and serving as a food source.
Reproduction of Rhizopus
- Rhizopus reproduces sexually under unfavourable conditions, such as drought or unsuitable temperatures, enhancing survival.
Asexual Reproduction in Yeast
- Yeast reproduce asexually through a process called budding, allowing rapid population growth in suitable environments.
Functions of Rhizopus Structures
- The stolon in Rhizopus spreads over the food surface, facilitating the growth of new mycelium.
- Rhizoids serve to increase surface area for nutrient absorption and aid in substrate digestion.
