Accordingly, which of the following are the two main components of cellular membranes?
The major components of a cell membrane are phospholipids, glycolipids, proteins, and cholesterol. The cell membrane contains more protein by mass, but the molar mass of a protein is about 100 times that of a lipid.

What is the function of the Golgi apparatus?
The Golgi apparatus is an organelle present in most eukaryotic cells. It is made up of membrane-bound sacs, and is also called a Golgi body, Golgi complex, or dictyosome. The job of the Golgi apparatus is to process and bundle macromolecules like proteins and lipids as they are synthesized within the cell.What are the three organelles that plant cells have but animal cells do not?
Most organelles are common to both animal and plant cells. However, plant cells also have features that animal cells do not have: a cell wall, a large central vacuole, and plastids such as chloroplasts.What is the major function of chloroplasts?
The chloroplasts with the nucleus and cell membrane and ER are the key organelles of pathogen defense. The most important function of chloroplast is to make food by the process of photosynthesis. During the process of photosynthesis sugar and oxygen are made using light energy, water, and carbon dioxide.What organelle is most likely abundant in skeletal muscle cells?
mitochondria
What does the Golgi apparatus mainly functions to modify?
It has been likened to the cell's post office. A major function is the modifying, sorting and packaging of proteins for secretion. It is also involved in the transport of lipids around the cell, and the creation of lysosomes. The sacs or folds of the Golgi apparatus are called cisternae.Which parts of a cell is most like the shipping center of a company?
