To study mushroom parts, collect a mature mushroom and observe its external parts—cap, stalk and gills—using a magnifying glass. With a foldscope or microscope, examine spores and cell structures on the gills. Seniors or teachers can guide you. This study helps understand fungi’s reproductive parts and structure, enhancing knowledge of non-green organisms that play important ecological roles in decomposition.

After interacting with a mushroom-growing entrepreneur, I learnt the following steps for cultivating mushrooms:
Steps for Mushroom Cultivation:
Selection of Mushroom Type
Common types include Oyster, Button, and Milky mushrooms. Each requires different conditions.
Preparation of Substrate
Substrate is the material used for growing mushrooms, such as paddy straw, sawdust, or compost.
The substrate is cut into pieces and soaked in water for several hours.
Pasteurisation
The wet substrate is steamed or heated to kill unwanted microbes. This prevents contamination.
Spawning
Mushroom spawn (seed) is mixed with the cooled substrate evenly.
Bag Filling and Incubation
The substrate with spawn is filled into poly bags or trays, with small holes for air.
Bags are kept in a dark, warm, and humid room (around 25–28°C) for 15–20 days until white fungal threads (mycelium) spread.
Fruiting Stage
After incubation, bags are opened and moved to a cooler, lighted space with good air circulation and high humidity.
Mushrooms start forming within 1–2 weeks.
Harvesting
Mushrooms are ready to be harvested when the cap opens fully. They are carefully twisted and plucked by hand.
Packaging and Selling
Fresh mushrooms are cleaned, packed in plastic trays or pouches, and sold in the market. Some are dried for storage.
🌱 Key Requirements:
Clean environment
Proper humidity and ventilation
Temperature control
Fresh, sterilised substrate
Hygiene to prevent contamination

Some microorganisms like mold colonies on bread and mildew are visible to the naked eye as tiny spots. Among living beings, tiny insects like ants, lice or fruit flies are often the smallest visible organisms. Observing these small life forms helps develop curiosity about the microscopic world that exists beyond what our eyes can easily see.
