Answer 1

Answer:

1:-A network of membranous tubules within the cytoplasm of a eukaryotic cell, continuous with the nuclear membrane. It usually has ribosomes attached and is involved in protein and lipid synthesis.

2:-The two types of endoplasmic reticulum are : Rough Endoplasmic Reticulum: Their main function is produce proteins in the cells and ribosomes are attached to their surface. Smooth Endoplasmic Reticulum: Their main function is to produce lipids and also detoxify toxins in the body in the liver and kidney cells.

3:-Biosynthesis is the process in your body that turns simple structures into more complex structures. It can happen within a single cell (or within a single organelle within a cell), or across multiple cells.
