| 11. | This release is then followed by protoplast fusion ( conjugation ) leading to formation of a diploid zygospore.
|
| 12. | Similarly, in Rhizaria, the ameboid, multinucleate protoplasts of some Cercozoan algae, e . g.
|
| 13. | Protoplasts from different species are induced to fuse by using an electric field or a solution of polyethylene glycol.
|
| 14. | An example of this is the measurement of the diffusion coefficient of a fluorescent lipid analogue in soybean protoplasts.
|
| 15. | It also produces a chitinase A able to produce protoplasts from " Schizophyllum commune " cultured mycelia.
|
| 16. | All tracheary elements develop a thick lignified cell wall, and at maturity the protoplast has broken down and disappeared.
|
| 17. | His protista were divided into moneres, protoplasts, flagellates, diatoms, myxomycetes, myxocystodes, rhizopods, and sponges.
|
| 18. | A remnant of the inner layer may be persistent and adhere to the protoplast after it has emerged from the spore.
|
| 19. | At maturity the protoplast the living material of the cell dies and disappears, but the lignified cell walls persist.
|
| 20. | A year later, during his studies of their osmotic behavior, he discovered and described the occasional fusion of naked protoplasts.
