Homework Answers
Cell
Robert Hooke Discovered and coined the term cell in 1665
Robert Brown Discovered Cell Nucleus in 1831
Schleiden and Schwann Presented The cell theory, that all the plants and animals are
composed of cells and that the cell is the basic unit of life.
Schleiden (1838) and Schwann (1839).
With the discovery of the electron microscope in 1940, it was possible to observe and
understand the complex structure of the cell and its various organelles.
Plasma Membrane or Cell Membrane
Cell membrane is also called the plasma membrane.
It can be observed only through an electron microscope.
Plasma membrane is the outermost covering of the cell that separates the contents
of the cell from its external environment.

2. Osteocytes are living cells surrounded by hard, mineralized extracellular matrix. With reference to the roles played by each of these labelled components of the osteon, explain: how is it possible for the osteocytes to remain alive despite being almost completely surrounded by impermeable extracellular matrix? You might start by asking yourself: in general, what do cells need in order to stay alive? Think back to your pre-lab work: here is another chance for you to write an explanation, this...

Many cells in the human body maintain an electric potential difference across their cellular membranes, typically through the use ion-specific pumps and channels that generate an excess of negative charges on the inside of the cellular membrane and an excess of positive charges on the outside. Let us estimate the total energy stored in the human body by this type of charge separation. Part a Different cells can have vastly different cell sizes; but as an approximation, let us assume...
