Detailed explanation-1: -Endoplasmic reticulum is an organelle found in both eukaryotic animal and plant cells.
Detailed explanation-2: -What is the endoplasmic reticulum? The endoplasmic reticulum (ER) is a continuous membrane system that forms a series of flattened sacs within the cytoplasm of eukaryotic cells. All eukaryotic cells contain an ER. In animal cells, the ER usually constitutes more than half of the membranous content of the cell.
Detailed explanation-3: -The endoplasmic reticulum (ER) in animal cells is an extensive, morphologically continuous network of membrane tubules and flattened cisternae.
Detailed explanation-4: -This compartment is involved in cell to cell communication via the plasmodesmata, and, in specialized cells, it serves as a storage site for proteins. The plant ER is also equipped with enzymes and structural proteins which are involved in the process of oil body biogenesis and lipid storage.
Detailed explanation-5: -An animal cell, a plant cell and a bacterium share the following structural features. A. Cell membrane, endoplasmic reticulum, vacuoles.
