Cell ultrastructure

Using a light microscope, you can see stained blood cells well enough to pick out the nucleus of leucocyte. However, the cytoplasm of leucocytes and most other human cells contains many other smaller structures, called organelles. Most organalles can not be seen with light microscope. A much more powerful kind of microscope, called an electron microscope, is needes.
This is a picture that show parts of cell
TEM of frog leucocyte

All cells are surounded by a thin layer made up of protein and lipid molecules. This membrane is known as the cell surface membrane. There are also other membranes inside the cell. The cell surface membrane controls what enter and leaves the cell. Subtances such as oxygen, water, carbondioxide etc.The cell surface membrane alsa containes glycoproteins and glycolipids.

What is kind of chordata superclass? You should read this article

Vertebrates are divided into two groups based on the presence and absence of the mouth jaw.They are Agnatha and Gnathosmata

Superclass Agnatha

It has long body without mouth jaw (jaw=rahang). The example of this superclass are Cephalospidomorphi (lamprey) and Class Mycini (hagfish). The habitat of lamprey in fresh waters and sea. Hagfish only live in sea.Hewan larva.Their food is dead fish. They suck the blood of dead fish.

Superclass Gnathostomata

This animal has a  jaw . It can be moved up and to down. This superclass is classified into six classes:
. They are chondrichtyes, osteichtyes, amphibi, reptil, aves, and mamalia, For more information, look at LKS biologi,, please!
