DIVISION CRYPTOPHYTA PDF

Asexual reproduction is done Cryptophyta division through mitosis. Mitosis is the division of body cells. Cells also undergo cytokinesis that is. The unicellular flagellates belonging to the division Cryptophyta are asymmetric cells dorsiventrally constructed (Figure ). They bear two unequal, hairy. Just before cell division, new kinetosomes and undulipodia appear with a new The Cryptophyta, cryptomonads or cryptophyte algae, have chloroplasts that.

Most cryptomonads are photosynthetic and are thus referred to as cryptophytes and possess plastids that are very diverse in pigmentation Figure 1. In all phylogenetic trees, the photosynthetic cryptophytes are subdivided into five clades and two single-strain lineages Figure 7: In addition to fine filaments, one cryltophyta is covered with a row of curved spikes that probably impede a cryptophyte-like swimming behaviour Kugrens et al. Cells also undergo cytokinesis that is, a process of division of the cytoplasm of the posterior end.

These three lineages each possess a secondary plastid of red algal origin, and it has been hypothesized that this organelle originated in a single endosymbiotic event in their common ancestor, and possibly much earlier, in cyrptophyta common ancestor shared by chromists and alveolateswhich are comprised of dinoflagellates, apicomplexans and ciliates.
