TaigaFactors such as inadequate water, sunlight, nutrients, and soil pH can prevent a plant from growing properly. Pests, diseases, and extreme weather conditions can also hinder plant growth. Additionally, overcrowding or competition with other plants for resources can inhibit a plant's growth.
The kind of environment needed to grow fungi is in wet or damp places such as: • On the end of cold water taps (usually kitchen or bathroom) • In washing machines (particularly around the powder drawer) • In filter jug hoppers and elements • In toilet cisterns and bowls • In shower heads • Around tiles in bathrooms / shower rooms • On shower curtains or towels (often appears as spots or staining) • In waste traps connected to sinks so if that does not help then i cant do much more.
Factors that affect the growth of mouldsSeptember 14, 2005 By MBL
The major factors affecting growth of mould are nutrients, temperature, light, aeration, pH and water activity.
Nutrients
Nutrient requirements for moulds may vary from mould to mould. Some moulds may thrive well on substrates with high sugar or salt content. Some may prefer simple sugars while others have the ability to utilize complex sugars.
Temperature
The majority of moulds are mesophilic, i.e., they can grow at temperatures within the range of 10-35°C. Optimum temperatures for growth may range between 15 and 30°C. However, some moulds such as Chaetomium thermophilum and Penicillium dupontii are thermophilic, i.e., they can grow at 45°C or higher and fail to grow below 20°C. A few moulds are psychrophilic and are unable to grow above 20°C. A significant number are psychrotolerant and are able to grow both at freezing point and at room temperature.
Light
Many moulds species grow well in the dark, but some prefer daylight or alternate light and darkness for them to produce spores.
Aeration
Nearly all moulds require air to grow.
pH.
Moulds differ in their pH requirements. Most will grow well over the pH range 3-7. Some such as Aspergillus niger and Penicillium funiculosum can grow at pH 2 and below.
Water activity
All moulds require moisture for growth but the amount required varies widely. Moulds that are capable of growing at very low water activity are referred to as xerophiles, for examples Eurotium species and Wallemia sebi. Those that are capable of growing at very high water activity are referred to as hydrophilic, e.g., Stachybotrys, Chaetomium and Ulocladium.

Can half a seed grow?
No, half a seed cannot grow. A seed needs to be intact in order to germinate and grow into a plant. Cutting a seed in half would prevent it from being able to sprout and develop into a plant.
What would happen if a plant did not have chloroplast?
The plant would die. Chloroplast turns light into energy and without energy the plant would eventually die.
Why are stomata located on the underside of the leaf?
As the upper surface is covered with a waxy cuticle which protects the plant from dehydration if the stomata were covered by a cuticle they would not be able to function.
What would happen if all of the leaves were removed from a plant system?
If all the leaves were removed from a plant, it would not be able to perform photosynthesis, which is essential for producing energy and nutrients. This would eventually lead to the plant being unable to sustain itself and it could die. Leaves are necessary for a plant's growth, development, and overall health.
What would happen if plant cells had no chlorophyll?
The cells would be unable to photosynthesise, and no glucose would be made. Therefore the plant would not be able to sustain itself and would simply die.
