Sarcodina is a superclass of the phylum Protozoa, members of which are known as Sarcodine. These have streaming cytoplasm and use pseudopodia in locomotion and feeding. What else do you know about them? Let’s take a look.

Questions and Answers

1.

Subphylum SarcodinaThese protozoa are characterized by possessing _______ for locomotion and capturing ___.

Explanation
Subphylum Sarcodina refers to a group of protozoa that are known for their method of locomotion using pseudopodia, which are temporary extensions of the cell membrane. These pseudopodia help them move and capture their food. Therefore, the correct answer is "pseudopodia food."

2.

Subphylum SarcodinaOrder amoebidaCommon genus of amoebida is ___

Explanation
The correct answer is Entamoeba. In the subphylum Sarcodina, the order Amoebida is commonly associated with the genus Entamoeba. This genus includes various species of amoebas that are known to be parasitic in nature and can cause diseases such as amoebic dysentery. Therefore, based on the information provided, Entamoeba is the most likely and appropriate answer.

3.

Subphylum Sarcodina Order amoebidaEntamoeba is found in the ___ _____ of vertebrates

Explanation
Entamoeba is a type of amoeba that is commonly found in the large intestine of vertebrates. This is because the large intestine provides a suitable environment for Entamoeba to thrive, as it offers the necessary nutrients and conditions for their survival. The large intestine is also where the majority of the digestion and absorption of nutrients takes place, making it an ideal habitat for Entamoeba.

4.

Subphylum Sarcodina Order amoebidaThe two important species are Entamoeba are E.____ and E._____ which are parasites of ____ and other primates although ____ may occasionally be infected

Explanation
Entamoeba histolytica and Entamoeba dispar are two important species belonging to the Order Amoebida in the Subphylum Sarcodina. These species are parasites that primarily infect humans and dogs, although other primates may occasionally be infected as well.

5.

Subphylum Sarcodina Order amoebidaonly E. histolytica is capable of invading the ___ and of affecting other organs via the circulatory system, particularly the ___ and also less commonly the ____ and brain

Explanation
The correct answer is "mucosa, liver, lungs". The question is asking which organs can be affected by E. histolytica, specifically through invasion of the mucosa and spread via the circulatory system. E. histolytica is capable of invading the mucosa, liver, and lungs, and can affect these organs through its invasive abilities and spread through the circulatory system.

6.

Subphylum Sarcodina Order amoebidaMucosal invasion from E. hystolytica gives rise to the characteristic bloody ___ of _____ which can be life threatening if not treated

Explanation
Mucosal invasion from E. hystolytica can lead to the development of dysentery, a condition characterized by bloody stools. This condition, known as amoebiasis, can be life-threatening if left untreated.

7.

Subphylum Sarcodina Order amoebidaEntamoeba's lifecycle is ___ (direct or indirect)

Explanation
The correct answer is "direct" because the term "direct" refers to a lifecycle in which the organism goes through a single host and does not require an intermediate host or vector for completion. In the case of Entamoeba, it undergoes a direct lifecycle as it goes through various stages (trophozoite and cyst) within a single host, typically a human.

8.

Subphylum Sarcodina Order amoebida transmission of Entamoeba is by ____ of cysts

Explanation
The correct answer is ingestion. Entamoeba, a type of amoeba, is transmitted through the ingestion of cysts. Cysts are a dormant form of the parasite that can survive outside the host and can be ingested through contaminated food or water. Once inside the body, the cysts can transform into the active form of the parasite and cause infection.

9.

Subphylum Sarcodina Order amoebida As with Giardia, cysts are capable of surviving in _____ _______ for extended periods but are susceptible to ___ temperatures and desiccation

Explanation
Cysts of the Order amoebida, similar to Giardia, have the ability to survive in the environment for long periods of time. However, they are vulnerable to high temperatures and desiccation.

4
10.

Subphylum Sarcodina Order amoebidaTransmission is usually by ___ faecal-___ transmission, via contaminated ___, or coprophagous ___ which can act as mechanical ___.

Explanation
The correct answer is "direct oral food insects vectors." In the subphylum Sarcodina, transmission is usually through direct oral ingestion of contaminated food or water. Insects can also act as vectors, carrying and spreading the disease-causing organisms.

11.

Subphylum Sarcodina Order amoebida It is important to catch E. histolytica early before stages reach ____ _____.

Explanation
It is important to catch E. histolytica early before stages reach internal organs because once the parasite reaches the internal organs, it can cause severe damage and lead to serious health complications. By detecting and treating the infection early, the spread of the parasite can be prevented, reducing the risk of organ damage and improving the chances of a successful recovery.

12.

Subphylum Sarcodina Order amoebidathe more scientific name for the "brain eating amoeba" is _____ (to Genus level)

Explanation
The correct answer is Naegleria. Naegleria is the more scientific name for the "brain eating amoeba". This amoeba belongs to the order Amoebida within the subphylum Sarcodina.

13.

Subphylum Sarcodina Order amoebidaInfection of Naegleria is contracted through the ___ cavity

Explanation
Naegleria is a type of amoeba that causes infection. The infection is contracted through the nasal cavity, which means that the amoeba enters the body through the nose. Once inside, it can travel to the brain and cause a severe and often fatal condition known as primary amoebic meningoencephalitis (PAM). This infection is rare but extremely dangerous, so it is important to take precautions to prevent exposure to Naegleria, such as avoiding warm freshwater sources like hot springs and poorly chlorinated swimming pools.

Rate this question:

14.

Subphylum Sarcodina Order amoebidaNaegleria reaches the brain through the nasal cavity via the ____ nerve

Explanation
Naegleria, an organism belonging to the Order Amoebida in the Subphylum Sarcodina, is known to reach the brain through the nasal cavity. It does so by utilizing the olfactory nerve, which is responsible for the sense of smell. This nerve connects the nasal cavity to the brain, allowing Naegleria to migrate from the nasal passages to the brain, leading to a potentially fatal condition called primary amoebic meningoencephalitis.

15.

Subphylum Sarcodina Order amoebidatrue or falseonce Naegleria reaches the brain tissue and multiplies, this disease is fatal?

Explanation
Once Naegleria reaches the brain tissue and multiplies, this disease is fatal. Naegleria fowleri is a brain-eating amoeba that causes a rare but severe infection called primary amebic meningoencephalitis (PAM). The amoeba enters the body through the nose and travels to the brain, where it causes inflammation and destruction of brain tissue. PAM is almost always fatal, with a very low survival rate. Therefore, if Naegleria reaches the brain tissue and multiplies, the disease is indeed fatal.

16.

Subphylum Sarcodina Order amoebidatrue or falseNaegleria infections can be transmitted from one person to the next?

Explanation
Naegleria infections cannot be transmitted from one person to another. Naegleria is a type of amoeba that is commonly found in warm freshwater environments. Infections occur when the amoeba enters the body through the nose and travels to the brain. This typically happens when individuals engage in activities like swimming or diving in contaminated water. However, Naegleria infections are not contagious and cannot be transmitted from person to person through direct contact or respiratory droplets.
