C (Point mutation)

Explanation:

Mutation is any change, no matter the degree or size, that occurs in a nucleotide sequence of a DNA. It occurs naturally due to mistakes during replication or can be induced by mutagens (mutation-causing components). A mutation is regarded to be POINT MUTATION, if it affects only a single nucleotide in the sequence.

Point mutation occurs in scenarios whereby a single base pair/nucleotide is substituted/replaced, deleted/removed from the sequence, or inserted/added. This sorts of mutation can yield beneficial or harmful effect in the organisms they occur.

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.
