How to make a Simplified Archegonium |
|
|
|
The first step is a Periclinal division in the Epidermis which produces and Inner and Outer Cell. |
The Inner Cell undergoes a series of Periclinal Divisions to produce a vertical cell file called the Axial Row. |
|
|
| Most of the cells become the Neck Canal. The lowest cell becomes the Egg. | The Outer Cell undergoes two Anticlinal Divisions to produce four surface cells. They continue to divide Periclinally and produce the four columns of the Neck. |
Note that the Egg is usually buried inside the Gametophyte. I made it visible so that you could see the relationship between the cells. |
