10 Questions
What are two characteristics of unicellular eukaryotes known as protozoa?
Absence of a cell wall and presence of at least one motile stage in life cycle.
What is the movement method of Amoeba proteus?
Pseudopodia ('false feet').
What is the method of eating for Amoeba proteus?
Phagocytosis.
How does Amoeba proteus reproduce?
Asexually through binary fission and sexually through flagellated gametes.
Name an example of a parasitic protozoa mentioned in the text.
Entamoeba like E. gingivalis found in the mouth.
Describe the movement method of Amoeba proteus and provide an example of its function in the text.
Amoeba proteus moves using pseudopodia, which are 'false feet' that create a leg on the fly. This movement method allows Amoeba proteus to capture and engulf its prey, such as algae, bacteria, unicellular eukaryotes, rotifers, and other microscopic organisms through phagocytosis.
Explain the process of reproduction in Amoeba proteus, detailing the two different methods mentioned in the text.
Amoeba proteus reproduces asexually through binary fission, where the cell divides into two identical daughter cells. It can also reproduce sexually using flagellated gametes.
Discuss the role of the contractile vacuole in Amoeba proteus and its significance in the organism's life cycle.
The contractile vacuole in Amoeba proteus serves as an organelle for osmoregulation, expelling excess water from the cell by releasing a clear bubble. This process is vital for maintaining the cell's internal balance and preventing it from bursting due to osmotic pressure.
Provide an example of a parasitic protozoa mentioned in the text and briefly describe its parasitic behavior.
An example of a parasitic protozoa mentioned in the text is Entamoeba, such as E. gingivalis found in the mouth. This parasitic protozoa can cause oral infections and other related health issues.
Name and describe a unique characteristic of the Phylum Euglenozoa and its significance in the context of unicellular eukaryotes.
Phylum Euglenozoa is known for its unique feature of having a flagellum, which is essential for movement and navigation in its environment. This characteristic distinguishes Euglenozoa from other unicellular eukaryotes and contributes to its ecological adaptation.
