Question
The bar graphs show the mean total amount of each element weathered from rocks in the control and experimental microcosms Mineral content n e microcosms Mineral content in andesite microcosms Control Control men Experimental 2. 2. Element Element Overall, what is the effect of moss on the chemical weathering of rock? It is not clear whether or not moss increases the chemical weathering of rock. Moss increases the chemical weathering of rock. Moss does not increase the chemical weathering of rock.Explanation / Answer
1. Option B is correct.
As we can clearly observe that the proportion of elements in the experimental set is higher than the control set up, it is clear that mosses increase the chemical weathering of both the rocks.
2. Option D is correct.
Flower of stone = Selaginella lepidophylla = Resurrection plant = Spike moss
Dominant generation in selaginella = Sporophyte
It contains lignified vascular tissues, haploid spores, true roots and microphylls.
