| 1. | Its first plate occupies 30 % of the width of the hypotheca.
|
| 2. | The hypotheca has four large plates that constitute the majority of the cell.
|
| 3. | Qui potiores in pignore vel hypotheca habeantur " was published in 1755.
|
| 4. | The cell then synthesizes a new hypotheca.
|
| 5. | One half, the hypotheca, is slightly smaller than the other half, the epitheca.
|
| 6. | The smaller theca is usually thought of as " lower, " and is thus called the hypotheca.
|
| 7. | The body is laterally compressed with a small, cap-like epitheca and a much larger hypotheca.
|
| 8. | As the diatom prepares to separate it undergoes several processes in order to start the production of either a new hypotheca or new epitheca.
|
| 9. | The anterior end has a crown-like platform, which is the smaller epitheca; while the posterior is simply rounded constituting a larger hypotheca.
|
| 10. | This is used by each daughter cell as the larger frustule ( or epitheca ) into which a second, small frustule ( or hypotheca ) is constructed.
