What is true about protozoa?

protozoan, organism, usually single-celled and heterotrophic (using organic carbon as a source of energy), belonging to any of the major lineages of protists and, like most protists, typically microscopic. All protozoans are eukaryotes and therefore possess a “true,” or membrane-bound, nucleus.

Which of the following are characteristics of protozoans?

What are the characteristics of Protozoa? They are unicellular, chemoheterotrophs (get energy from breaking down organic matter), have special structures for ingesting food and are capable of reproduction.

What are protozoans quizlet?

What are protozoa? A diverse group of unicellular organisms that generally reproduce by binary fission; they are eukaryotic and therefore have metabolic systems much like humans (making them harder to treat than bacterial infections).

Which of the following organisms requires an additional non human host to complete its life cycle quizlet?

Which of the following organisms requires an additional nonhuman host to complete its life cycle? Plasmodium species. The life cycle of Plasmodium species requires two hosts, one of which is a mosquito.

What major characteristic is used to differentiate the phyla of protozoans?

Protozoa have an animal-like behavior whereas algae are considered plant-like. All protists have a true nucleus and require some form of moisture to survive.

What makes a protozoa a protozoa?

Protozoa are single-celled eukaryotes (organisms whose cells have nuclei) that commonly show characteristics usually associated with animals, most notably mobility and heterotrophy. … Protozoa have traditionally been divided on the basis of locomotion.

Which statement regarding helminths is true quizlet?

Which statement regarding helminths is true? They are always dioecious, which means that one individual has both male and female reproductive organs.

Which of the following protozoa has Pseudopods for motility?

The ameba, as exemplified by Amoeba proteus and Entamoeba histolytica, are amorphous and continuously change their shape as they move by extending portions of their body. These extensions are called pseudopodia (false feet) and this type of movement is called ameboid movement.

Which phylum of protozoa contains?

Protozoa can be divided into four phyla based on their locomotion: Mastigophora, Sarcodina, Ciliophora, and Sporozoa.

Which of the following statements is false about fungi?

The false statement is, they possess a purely cellulosic cell wall. The cell wall of the fungi do exist but the main structural component of the cell wall of the fungi is not cellulose. The chitin is the main structural component of the cell wall of the fungi.

What observations or tests would you perform to determine whether this organism is a protozoan fungus or alga?

The presence of a cell wall would indicate the organism is either a fungus or an alga. The presence of pigments is an indication it is a photosynthetic organism, and if it has a cell wall it is an alga. The identification would be further confirmed if the organism is diploid (observed during mitosis).

In which group of protozoa is Toxoplasma classified?

Toxoplasma gondiiInfrakingdom:AlveolataPhylum:ApicomplexaClass:ConoidasidaOrder:Eucoccidiorida

Which one of the following is true for fungi?

Fungi are achlorophyllous, heterotrophic, spore forming, non-vascular, eukaryotic organisms which often contain chitin or fungal cellulose in their walls. Hence, their cell wall is rigid.

Which is not true for mycoplasma?

They lack a cell wall. They are the smallest living cells. They cannot survive without oxygen. They are pathogenic in plants and animals.

Which of the following statements about helminths is false?

The statement that is false about helminths is (d) all are parasites . Helminths are eukaryotic organisms and are either parasitic or free living wo…

Which one of the following statement is not true about lichens?

“Which one of the following is not true about lichens?” (d) Statement (d) is incorrect because lichens show very slow growth. Their size and slow rate of growth suggest that some lichens in the Arctic are 4000 years ago.

What are true fungi give example?

any member of the kingdom Fungi (or division Thallophyta of the kingdom Plantae), comprising single-celled or multinucleate organisms that live by decomposing and absorbing the organic material in which they grow: includes the mushrooms, molds, mildews, smuts, rusts, and yeasts.

Which of the following is true about fungi Imperfecti?

They are known as Imperfect Fungi because only their asexual and vegetative phases are known. They have asexual form of reproduction, meaning that these fungi produce their spores asexually, in the process called sporogenesis.

What is true about lichens?

A lichen is a composite organism that emerges from algae or cyanobacteria living among the filaments (hyphae) of the fungi in a mutually beneficial symbiotic relationship. The fungi benefit from the carbohydrates produced by the algae or cyanobacteria via photosynthesis.

Why do lichens indicate so2 pollution?

Therefore, they are used as an indicator to detect the presence of sulphur dioxide. Presence of sulphur dioxide reduces the rate of growth of lichens because lichens are highly sensitive towards sulphur dioxide. $ \Rightarrow $ Lichens indicate $S{O_2}$pollution because they Are sensitive to $S{O_2}$.

Which of the following is incorrect for lichens * A They are an example of symbiotic association B algal component of lichens is known as Mycobiont C the?

Since they are the association of algae and fungi, we can say that the algal component of lichens is known as phycobiont. While the fungal components of lichen are known as mycobionts. So, the correct answer is ‘Lichens do not grow in unpolluted areas’.
