Study the different parts of a macro fungus mushroom using a magnifying glass and microscope/foldscope. Take the help of students from senior classes and explore the internal structure of different parts of mushrooms under the microscope/foldscope in your school laboratory.
When observing a mushroom under a magnifying glass and microscope, the following structures can be identified.
The cap (pileus) is the umbrella-shaped top that protects the spore-producing structures underneath. The gills (lamellae) are thin, radiating structures under the cap where spores are produced. The stem (stipe) supports the cap and transports nutrients.
Under a microscope, the gills reveal basidia—spore-producing cells that release tiny spores. The internal structure shows thread-like structures called hyphae, which intertwine to form a network called mycelium.
The cell walls of fungal cells are visible, but unlike plant cells, fungal cells lack chloroplasts. The cytoplasm and nucleus can be observed within each cell.
Mushrooms are multicellular fungi that reproduce through spores.
Explanation
Section 2.3 explains that fungi can be unicellular (like yeast) or multicellular (like mould). Section 2.5 states that cells of fungi have a cell wall but do not have chloroplasts, so they cannot make their own food through photosynthesis. The chapter encourages students to use microscopes and foldscopes to observe microorganisms and their structures.
Solution Steps
Identify external structures: cap (pileus), gills (lamellae), and stem (stipe)
Observe microscopic structures: basidia (spore-producing cells), hyphae, and mycelium network
Note cell features: cell walls present, absence of chloroplasts, visible cytoplasm and nucleus
Recognize mushrooms as multicellular fungi that reproduce through spores
