D2_003_paramécies_conjugaison_paramecia_Paramecium caudatum

            100x. Conjugaison. Comme tous les infusoires, la paramécie est dotée d'un double appareil nucléaire : le macronoyau (masse sombre) et le micronoyau (non visible). 
Le macronoyau, polyploïde, contrôle les fonctions trophiques, de maintien en vie et de croissance, alors que le micronoyau assure les fonctions sexuelles indispensables à la variabilité génétique. Cette dernière est assurée par le processus de conjugaison au cours duquel deux paramécies s'accolent et échangent leurs micronoyaux haploïdes.

100x. Conjugaison. Paramecium, like other ciliates, have two nuclei, a large macronucleus and a small micronucleus. The macronucleus is the centre of all metabolic activities, and the micronucleus is the storage site for the germline genetic material. The latter is implicated in the process of sexual reproduction, by means of conjugation in which cross-fertilization is achieved by the exchange of genetic material (haploid nuclei)

- In order not to overload the images, the latter do not contain any annotations, or the bare minimum. For more details about this micrography, please refer to specialized literature or contact Franck Genten : fgenten@gmail.com
