The rough endoplasmic reticulum also known as RER is covered in ribosomes and helps produce most of the proteins. Smooth endoplasmic reticulum also known as SER does not have these ribosomes, and it is almost solely for producing lipids.
Good luck :)
The plant cell has a cell wall, chloroplasts, plastids, and a central vacuole—structures not found in animal cells. Plant cells do not have lysosomes or centrosomes.
