Which of the following is a protozoa with two nuclei and no mitochondria?
Which of the following is a protozoa with two nuclei and no mitochondria?
Members of the diplomonad subgroup of archaezoans have two flagella, two nuclei, and no mitochondria. Giardia lamblia, an intestinal parasite that causes giardiasis, is a member of this group.

What is the composition of lichens and what is the role of each organism in lichens?
The alga produces the food through photosynthesis, and the fungus protects the alga and provides nutrients and water for their combined survival. This unique combination allows lichens to survive where many other organisms cannot.
Are protozoa diploid?
Many of them have multiple life stages that are dependent on the host, and some require multiple hosts. Moreover, many protozoa have haploid genomes, others are diploid, some are haploid only over part of their life cycle, and yet others have poorly defined ploidies.
What are the three groups of protozoans?
There are three major categories of protozoa: the flagellates, the amoebae, and the ciliates. The flagellates are the smallest of the protozoa and move by means of one to several flagella.
Are diatoms prokaryotic or eukaryotic?
eukaryotic
Diatoms are eukaryotic microalgae which have a different phylogenetic origin than green algae, the green lineage mosses, ferns and higher plants. The diatoms developed from a secondary endocytobiosis of a eukaryotic host and a eukaryotic red alga.
How are diatoms different from other eukaryotic cells?
A unique feature of diatom anatomy is that they are surrounded by a cell wall made of silica (hydrated silicon dioxide), called a frustule. These frustules have structural coloration due to their photonic nanostructure, prompting them to be described as “jewels of the sea” and “living opals”.
