When a cell divides, each daughter cell must receive its full complement of genetic material in the form of chromosomes containing DNA, or deoxyribonucleic acid. A chromosome is made up of two long strands of DNA and several types of proteins . A DNA strand is composed of a long backbone of sugar and phosphate units . One of our different nucleotide bases -- A, T, C or G -- hang off each sugar unit. The sequence of the bases encodes genetic information. The three steps in the process of DNA replication are initiation, elongation and termination

The correct answer is - b. make their own food.
The plants are differing from most of the other organisms in that that they produce their own food. In order to produce their own food, the plants use the sunlight, carbon dioxide, water, and nutrients from the soil. They manage to perform a process called photosynthesis in which they manage to turn those things into sugars, thus create their own food. That makes the plants producers, which puts them on the bottom of the food chain, meaning they are the basis and most important part of the ecosystems in which they exist.
