Identify a specific example where the cell wall structure has aided the survival of a plant in its natura habitat

The plant's species has an advantage over the animals as they possess an extra layer around the plasma membrane called the cell wall.

The cell wall is composed of the cellulose, pectin and hemicellulose which provides mechanical strength and toughness to the plants as well as they help protect the plant from the external environment.

Since cell wall provides mechanical strength to the plant therefore, plants have got the ability to stand upright to a height.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
