What else can I help you with?
Organelles found in algae but not found in protozoa or fungi?
Flagella, pyrenoids, chloroplasts, and eyespots are organelles commonly found in algae but typically absent in protozoa or fungi.
What are the osmoregulatory organelles in protozoa?
In protozoa, osmoregulatory organelles primarily include contractile vacuoles and, in some cases, food vacuoles. Contractile vacuoles help regulate osmotic pressure by expelling excess water that enters the cell through osmosis. These organelles are especially important in freshwater protozoa, where the external environment is hypotonic compared to the cell's internal environment. Additionally, some protozoa may use specialized structures like pulsatile vacuoles to assist in osmoregulation.
What organelles function in the maintenance of water balance in freshwater protozoa?
plasma membrane. it controls the water movement through osmosis.
Do protozoa contain DNA?
Yes,as eukaryotes they have several organelles which includes at least one nucleus which contains most of the cell's DNA
What is the division of labor in protozoa?
Q. Division of labour in protozoa?Ans: no physiological division of labour in protozoa hence they are acellular or unicelluar****************THANK YOU********************written by: NEELAM KHANJINNAH UNIVERSITY FOR WOMENKarachi, pakistan

Why are bacteria different from protozoa?
Basically because bacteria are prokaryote and protozoa ( protists ) are eukaryote. Prokaryote cells are simple cell of no nucleus or membrane bound organelles. Eukaryote cells have their genetic material in a membrane bound nucleus and have many membrane bound organelles.
How do ciliates?
Ciliates, a unicellular protozoa, use their cilia, tiny hair-like organelles, to move around.
Is protozoa a eukaryote?
Yes, they have a membrane bound nucleus and membrane bound organelles.

Are protozoa prokaryotic cells?
No. Protozoa are Eukaryotic and unicellular organisms because they possess nucleus while prokaryotes are organisms which lack a nucleus in cell ..
What types of microbes are eukaryotic?
Some examples of eukaryotic microbes include protozoa, algae, fungi, and some parasites. These organisms have a well-defined nucleus and other membrane-bound organelles within their cells. Eukaryotic microbes can be found in various environments, ranging from soil and water to the human body.
Do protozoa have plastids?
Protozoa generally do not have plastids, as these organelles are primarily found in plants and some algae, where they are involved in photosynthesis. However, certain protozoan groups, such as euglenoids, contain plastid-like structures called chloroplasts that allow them to perform photosynthesis. These chloroplasts are derived from endosymbiotic algae. Overall, while most protozoa lack plastids, some specialized forms do possess them.
What are the main features of protozoa?
Protozoa are single-celled eukaryotic organisms characterized by their diverse shapes and sizes. They typically possess organelles such as a nucleus, mitochondria, and sometimes specialized structures like cilia or flagella for movement. Protozoa can be heterotrophic or autotrophic, feeding on bacteria, algae, or organic matter. Additionally, they reproduce both sexually and asexually, showcasing a variety of life cycles and adaptations to different environments.
