List the characteristics of Fungi and draw a labeled diagram of a mould fungus. (b) How are fungi useful to man?

Here are the answers to question 1 in English: 1. (a) (i) List the characteristics of Fungi • Fungi are eukaryotic organisms. • They are heterotrophic, absorbing nutrients from their environment. • Their cell walls are made of chitin. • They primarily reproduce using spores. • They lack chlorophyll and cannot perform photosynthesis. • Their bodies are typically composed of thread-like structures called hyphae, which form a network called a mycelium. 1. (a) (ii) Draw a large labeled diagram of a mould Fungus such as a Bread Mould (Rhizopus) I cannot draw diagrams, but a diagram of Rhizopus should include and label the following parts: • Sporangiophore (the upright stalk) • Sporangium (the spherical structure at the top of the sporangiophore, containing spores) • Spores (the reproductive cells inside the sporangium) • Columella (the dome-shaped structure inside the sporangium) • Rhizoids (root-like structures that anchor the fungus and absorb nutrients) • Stolon (the horizontal hypha connecting sporangiophores) • Mycelium (the entire network of hyphae) 1. (b) How are Fungi useful to man? Fungi are useful to humans in several ways: • Food: Some fungi are edible (e.g., mushrooms), and yeast is used in baking bread and brewing alcoholic beverages. • Medicine: They are a source of antibiotics (e.g., penicillin) and immunosuppressants. • Decomposition: They break down dead organic matter, recycling nutrients in ecosystems. • Industry: Used in the production of enzymes, organic acids (e.g., citric acid), and vitamins. 1. (c) How would you test for the presence of reducing sugar in a piece of bread? To test for the presence of reducing sugars in bread, you would use the Benedict's test: Step 1: Prepare the sample. Crush a piece of bread and mix it with distilled water to create an extract. Filter the solution to remove solid particles. Step 2: Add Benedict's reagent. Add a few drops of Benedict's reagent to the bread extract in a test tube. Step 3: Heat the mixture. Heat the test tube in a boiling water bath for about 5 minutes. Step 4: Observe the color change. Observe any color change. The presence of reducing sugars is indicated by a color change from blue to green, yellow, orange, or a brick-red precipitate. 3 done, 2 left today. You're making progress.
