Question

In rainy season, while walking along road side,

Vivek asked his father (a botanist)whether some small green, non-flowering,leafy and thalloid plants having little differentiation of body and growing along pavement are of any use to us. Vivek’s father answered that these plants are small but they play very important role in maintaining green cover of the land.

• To which group these small thalloid, green, non-flowering plants belong?

• In what way bryophytes are useful to us?

• Which other groups of plants act as colonizers of barren rocks and make land suitable for growth of higher plants? Do these plants play some role in pollution

Answer 1

1)bryophytes

2)Bryophytes are very important in initiating soil formation on barren terrain, in maintaining soil moisture, and in recycling nutrients in forest vegetation. Indeed, discerning the presence of particular bryophytes is useful in assessing the productivity and nutrient status of forest types.

3)Mosses and Lichens act as colonizers of barren rocks and make land suitable for growth of higher plants. They are also good indicators of atmospheric quality. Yes these plants play a very important role in monitoring pollution. Ecosystems dominated by mosses and lichens are amongst the most sensitive to nitrogen pollution.
