Explanation / Answer

Q16. Endocytosis

In endocytosis, the cell engulfs some of its extracellular fluid including material dissolved or suspended in it.

Q17. Liver

Liver cells contain a large amount of smooth endoplasmic reticulum as liver functions to detoxify toxic substances. Smooth ER also plays a large part in detoxifying a number of organic chemicals converting them to safer water-soluble products.
