Is Chromista asexual?

Is Chromista asexual?

The genus belongs to the class Oomycetes in the Kingdom Chromista and is more closely related phylogenetically to the heterokont algae than the true fungi or Mycetae. Oomycetes are diploid, have a coenocytic thallus or mycelium, and they reproduce asexually to produce chlamydospores or by the production of sporangia.

Do Chromista have mitochondria?

A third character common to the Chromista is their mitochondrial architecture. Mitochondria are generally spherical organelles that have an outer membrane surrounding an inner membrane that folds (cristae) into a scaffolding for oxidative phosphorylation and electron transport from enzymes.

What makes Chromista unique?

Unlike plants, the Chromista have chlorophyll c, and do not store their energy in the form of starch. Also, photosynthetic chromists often carry various pigments in addition to chlorophyll, which are not found in plants. It is these pigments which give them their characteristic brown or golden color.

Is Chromista unicellular or multicellular?

Chromista is a biological kingdom consisting of single-celled and multicellular eukaryotic species that share similar features in their photosynthetic organelles (plastids). It includes all protists whose plastids contain chlorophyll c, such as some algae, diatoms, oomycetes, and protozoans.

Are Chromista motile?

Kingdom ChromistaCommon microorganisms; includes important plant pathogens, such as the cause of potato blight (Phytophthora); motile spores swim by means of 2 flagella and grow as hyphae with cellulose-containing walls; includes the majority of the Oomycota; contains a total of approximately 110 genera and 900…

Is Chromista pathogenic?

Is Chromista a photosynthetic?

The name Chromista means “colored”, and although some chromists, like mildews, are colorless, most are photosynthetic. Even though they are photosynthetic, chromists are not at all closely related to plants, or even to other algae.
