AP BIOLOGY

Detailed explanation-1: -Ecologically, the ferns are most commonly plants of shaded damp forests of both temperate and tropical zones. Some fern species grow equally well on soil and upon rocks; others are confined strictly to rocky habitats, where they occur in fissures and crevices of cliff faces, boulders, and taluses.

Detailed explanation-2: -There are four particular types of habitats that ferns are found in: moist, shady forests; crevices in rock faces, especially when sheltered from the full sun; acid wetlands including bogs and swamps; and tropical trees, where many species are epiphytes (something like a quarter to a third of all fern species).

Detailed explanation-3: -Ferns are easy to grow in water as long as you keep the following points in mind: Fern fronds, without attached roots, will not grow in water. However, they’ll last for some days. To successfully grow ferns in water, make sure that you keep the plant along with the roots in a vase or a glass bowl full of water.

Detailed explanation-4: -Moss and fern species are common in the forest understorey but not usually found in open, dry habitats (e.g., roadside at the start of the trail). The reason for this is that both moss and fern species are relatively primitive plants that are only imperfectly adapted to a terrestrial environment.
