dusya [7]

The plants can be classified based on their vascular and reproductive structures. The plant given in the image belongs to the Bryophyta.

<h3>What is Bryophyta?</h3>

The non-vascular plants that are a part of the plant classification are found in moist places and are small in size belongs to the Bryophyta.

The plant of this classification have a leafy multicelled plant body, that lacks true leaves, roots, and stems.  They are green plants and also contains chloroplast for food synthesis.

The vascular tissue like xylem and phloem are completely absent and hence the transportation does not occur through specialized systems.

Therefore, option A. Bryophyta is the plant growing on the rock.

Allushta [10]

Answer:

Mutation, Gene flow/Migration/Immigration of gene and Recombination

Explanation:

For any species there are majorly three sources of genetic variations –  

a) Mutation – This leads to change in the genetic code with in the DNA of an organism. Sometimes mutation does not produce any effect on the organism. Mutation can produce both positive and negative impact. Its effect is observed in long run as its rate is slow.

b) Recombination – When an organism undergoes sex, his/her genes recombine with the genes of mating partner. The rate of recombination is faster than the rate of mutation  

c) Gene flow /Migration/Immigration of gene – In this gene travel from one set of population to the other. The frequency of gene in the mixed population lies between the original population gene frequency and the migrated or donor population gene frequency
