Liverworts, like the one shown here, are nonvascular plants. They do not grow tall. Explain how the tissues in liverworts affect their size.

answer; the above answer to the above statement is (true)

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).

answer transpiration;
