Without a cell membrane, you arguably wouldn't have any cells. The cell membrane holds the contents of the cell together, and regulates what can get in and out. It is incredibly complex, with scientists continually learning new pieces of information everyday....
What is the secretory product of the parietal cell? What is the substance that can freely diffuse through the lipid bilayer of the plasma membrane? Fill in the blank: The cell membrane of a skeletal muscle cell is called the. Identify and name the following: It is the plasma membrane of ...
Integral membrane proteins are are embedded within the cell membrane and project into the cell or the external environment. An integral membrane protein that spans the entire cell membrane, from the outer surface of the cell to the inner surface of the cell, is called a transmembrane protein. ...

Nucleus is the organelle which encloses the genetic material in eukaryotic cell. It is a double membrane bound organelle. It also contains RNA and protein. It is the site of replication of DNA and formation of RNA.Answer and Explanation: Structure of Nucleus...
The fertilization of the human egg cell with spermatozoa As we have previously said, the function of the sperm is sexual reproduction. For this to happen, coitus between a man and a woman is necessary to bring their gametes into contact. ...
Cell Membrane Structure The cell membrane is two layers thick and made of tiny fat molecules calledphospholipids. The phospholipids are unique because the outside of them, or the heads, are hydrophilic, meaning they love water. These interact with the liquid solution inside and outside the cell...
Cell transport is a biological process through which materials pass into and out of cells, crossing the membrane or “outer wall” in the process. It happens in almost all organisms, and is an important part of cell health; it allows nutrients to come in and waste to go out, for one t...
