WebTransport of genetic information. The genetic information stored in the base sequence of genes is transferred through protein synthesis. This process requires transcription and … Webplant cell. Most plant cells contain one or more membrane-bound vesicles called vacuoles. Within the vacuole is the cell sap, a water solution of salts and sugars kept at high concentration by the active transport of ions through permeases in the vacuole membrane. Proton pumps also maintain high concentrations of protons in the vacuole interior ...
