B. plasma membrane
Explanation:
Both plants and animals are eukaryotic organisms, it means that their cells contain 1-a nucleus that has linear chromosomes and 2-membrane-bound organelles such as mitochondria and endoplasmic reticulum. Moreover, chloroplasts are organelles found in the cells of plants and algae. On the other hand, bacteria are prokaryotic unicellular organisms that have neither an envelope-enclosed nucleus nor other specialized organelles. Most bacteria contain a genome composed of a single DNA molecule (i.e., one circular chromosome).
