Select the correct answer using the code given below. a) 1 and 4 only b) 2 only c) 2 and 3 d) 1, 3 and 4
Answer: (c)
Lichens have specific requirements for their habitats. These requirements are: water, air, nutrients, light, and substrates. Lichens occur from sea level to high alpine elevations, in many environmental conditions, and can grow on almost any surface.
Mosses are non-flowering plants that produce spores and have stems and leaves but don’t have true roots. The individual plants are usually composed of simple leaves that are generally only one cell thick, attached to a stem that may be branched or unbranched and has only a limited role in conducting water and nutrients. Fern is a member of a group of vascular plants (plants with xylem and phloem). They grow in soils. Ferns require indirect sunlight, moist soil, and a humid atmosphere.
A mushroom or toadstool is the fleshy, spore-bearing fruiting body of a fungus, typically produced above ground, on soil, or on its food source.
