The answer to this question would be: on the rough endoplasmic reticulum.
Digestive cell produces many enzymes which were made by protein. Endoplasmic reticulum has a role in protein synthesis. It is important to have many rough endoplasmic reticulum to accommodate the protein synthesis function so that the digestive organ can produce enough enzyme
I think it will be RNA for both questions
The cell needs transcription because the DNA cannot leave the nucleus and therefore cannot transmit info to the other cells.
