smooth er is involved in protein synthesis, while rough er is involved in lipid synthesis
rough er is involved in lipid synthesis, while smooth er has ribosomes for protein synthesis
rough er has ribosomes for protein synthesis, while smooth er is involved in lipid synthesis
rough er is smooth in texture, while smooth er has a rough texture
both rough and smooth er have ribosomes for protein synthesis

Explanation:

The rough endoplasmic reticulum (RER) has ribosomes attached to its surface and is involved in protein synthesis. The smooth endoplasmic reticulum (SER) lacks ribosomes and is mainly involved in lipid synthesis.

Answer:

Rough ER has ribosomes for protein synthesis, while smooth ER is involved in lipid synthesis
