Ribosomes are not major components of the cell plasma membrane. However, the Golgi Apparatus and Endoplasmic Reticulum (ER) are major components of the cell plasma membrane. The Golgi Apparatus is involved in modifying, sorting, and packaging proteins for secretion, while the ER is responsible for protein synthesis and lipid metabolism.
The components of a conceptual model are all a part of the same system.
The two types of ER (Entity-Relationship) models commonly used in database design are the conceptual ER model, which describes the high-level concepts and relationships in a system, and the logical ER model, which defines the structure and constraints of the database in more detail.
The Entity-Relationship Model is often referred to as a semantic data model, because it more closely resembles real world scenarios than, e.g., the relational model. . In the ER model, we model the concept of "Instructors." In the relational model we deal with names and phone numbers. . In the ER model, there is a distinction between entities (objects) and relationships between such entities. In the relational model, both concepts are represented by relations.

Endoplasmic Reticulum or ER.
The components of Apple Iphone 4s and Apple Iphone 5 model are very different. The difference is in speed of the components, and obviously the size of components. Also, Iphone 5 has better components than Iphone 4s.
Fluid-mosaic model
Because it is very useful in mapping the meanings and interactions of real-world enterprises onto a conceptual schema. Because of this usefulness, many database-design tools draw on concepts from the ER-model. The ER data model employs three basic notation:a.) Entity setsb.) Relationship setsc.) Attributes.
Yes, the rough endoplasmic reticulum (ER) is involved in synthesizing phospholipids, which are key components of cellular membranes. It also synthesizes proteins that are bound for secretion or insertion into the cell membrane.
