Protozoa
Protozoans are unicellular organisms found in many different habitats. They are eukaryotic and can be predators, herbivores or parasites, depending upon the species. The well-known disease malaria is caused by a protozoa.

Euglena move using a long whip-like structure called a flagellum. By whipping its flagellum back and forth, Euglena can propel itself through the water in a corkscrew motion. This movement allows Euglena to navigate towards light sources for photosynthesis and escape from predators.
What kingdom does an Amoeba belong to?
Amoeba proteus, the common amoeba, is currently classified in Kingdom Amoebozoa. Older sources may list amoebae under the now-defunct Kingdom Protista or (in really old books) Kingdom Animalia. The change is because of the current trend to define taxonomic groups on evolutionary kinship.
How does an amoeba get its nutrients?
An amoeba gets nutrients through the process of endocytosis, which is absorbing another organism into itself. This is done with a pseudopod, which is a temporary appendage used for absorbing another organism.
Volvox is a colonial green algae that exhibits both individual and group motility using flagella. The coordinated beating of flagella enables Volvox colonies to move in a tumbling or rotating motion through the water. This motility allows them to regulate their position in the water column for optimal photosynthesis and nutrient uptake.
Amoebas feed by engulfing food particles through a process called phagocytosis. They extend their pseudopods around the food particle, forming a food vacuole that contains the particle. Digestive enzymes are then secreted into the food vacuole to break down the food for absorption.
Is protozoa the biggest microorganisms?
No. ....But as you probably guessed, they are related.
This is the naming system referred to as Traditional Whittaker system of classification.
There are 5 Kingdoms:
Monerans, Plants, Fungi, Animals, and PROTISTS.
Then you have those 5 broken down into subkingdoms, (then phylum, class, order, family genus, and species.) Protistshave 2 subkingdoms: Algae, and PROTOZOA.
(The Protozoa subkingdom consists of these 7 phyla: Sarcomastigophora, Ciliophora, Apicomplexa, Microspora, Ascetospora, Myxozoa and Labyrinthomorpha.) Protozoas are heterotrophs, which means, they rely on organic nutrition to get chemical energy.
So, not all Protists are Protozoa, some Protists are Algae.
I hope that helps.
Volvox moves by the coordinated beating of its flagella, which are whip-like appendages that extend outwards from the surface of the colonies. The flagella work together to propel the volvox through the water in a rolling motion.
Entamoeba is a Monogenetic or digenetic or polygenetic?
monogenetic. cause to complete its life cycle it requires only one host i.e. man.
Where can you find information on the parts of a paramecium?
yahoo answers is usually where i always go for first choice. but for background information use buzzle or ask.com it usually helps. Yes i know this the paramecium is a difficult topic.. but thats ok.
What is the economic importance of amoeba?
Amoebas play an important role in aquatic ecosystems as they help decompose organic matter, recycling nutrients back into the environment. They also serve as a food source for many organisms, contributing to the food web. Additionally, some amoeba species are used in research to study cell biology and genetics.
A paramecium is not autotrophic. A paramecium is heterotrophic. The paramecium are single-celled organisms that are found in marine environments and stagnant ponds.
Amoebas move by extending their cell membrane out in the direction they want to go, forming temporary protrusions called pseudopods. They then flow their cytoplasm into the pseudopods, allowing them to move in a process known as amoeboid movement.
Cells can move through a process called cell migration, which involves coordinated changes in the cell's shape and movement of its internal components. This can be driven by signals from the environment, such as chemical gradients or physical cues. Cells can move using structures like cilia, flagella, or by extending protrusions like lamellipodia and filopodia.
Euglena uses a long whip-like structure called a flagellum to propel itself through water. By moving its flagellum in a whip-like motion, euglena is able to swim and change directions to navigate its environment effectively.
Protozoa are classified based on their movement. They can be classified into four main groups: amoebae, flagellates, ciliates, and sporozoans. This classification is based on the structures they use for locomotion, such as pseudopodia, flagella, cilia, or lack of movement altogether.
All protists belong to the taxonomic domain of Eukarya, members of which are characterised by having cells with nuclei. Eukarya covers all organisms in the Kingdom Protista, as well as the Kingdoms Plantae, Fungi and Animalia.
Is amoeba proteus a heterotroph or an autotroph?
Amoeba is a heterotroph i.e they absorb their food directly from the external environment. Some are parasites. Amoeba eat algae, bacteria, plant cells and also protozoans.
Amoebas engulf their food. They are heterotrophs. They cannot make their own food.
Does an Amoeba have a endoskeleton or extoskeleton?
Any type of skeleton requires multiple cells to harden and support the animal. An amoeba is an invertebrate and a one-celled creature that barely has a cell wall. It surrounds its food with its body and then digests it. It has neither endo- or exoskeleton.
Protozoa can be found in a variety of habitats including freshwater, marine environments, soil, and even within the bodies of other organisms as parasites. They are adaptable and can thrive in diverse conditions ranging from hot springs to deep ocean trenches.
Paramecium are commonly used in scientific research as model organisms to study cell structure, physiology, and behavior. They are also used in ecological studies to indicate water quality and in educational settings as a model organism for teaching basic biological concepts. Additionally, some cultures consume paramecium as a food source, although this is less common.
Euglena is an unicellular organism that belongs to the kingdom Protista. It is found usually in water sources that have high levels of algae. Scientists believe that it can be helpful as a pollution indicator.
Why are animals smaller today than they were in the distant past?
Actually, the modern Blue Whale is still the largest animal that has ever lived, so your question should be "Are animals today smaller than they were in the distant past?" and the answer is "not really." That being said, during the age of mammals, certain representatives were larger than current representatives, such as the mammoths and mastodons for the elephants. However, one must keep in mind that there were many species in the elephant family, and many of them were smaller than today's elephants.
The discussions below seem highly speculative, but may be useful as hypotheses.
i can't give you a straight answer because there can be several things responsible. one is that there's less oxygen in the atmosphere now than in the past-about 1/2 as much. in the past animals could take in more oxygen and thus grow larger, basically. another answer comes from one of several evolution theories. over time, larger and smaller animals faded because larger ones were bigger targets (and of course not many carnivores were subject to this but when their food source dies off-large herbivores, so do they) and smaller ones were not adept at getting food easily. so you have a median-today's average size animals.
There were also horrible recordings of size. Inaccurate measurements had a lot to do with this. The mammoth was not really a "mammoth" but just a bit larger than modern day African elephants. An ecosystem may also not be able to support extremely large herbivores, like certain dinosaurs, and that causes a ripple effect through the entire food chain.
blue whale is not that large compared to the sauropod dinosaurs
Amoeba is considered an organism because it is a single-celled microorganism that exhibits all the characteristics of life, such as feeding, growing, and reproducing. It can carry out essential life processes independently.
Volvox are green due to the presence of chlorophyll, a pigment responsible for capturing light energy during photosynthesis. Chlorophyll gives volvox their green color by reflecting green light and absorbing other wavelengths. This allows volvox to convert sunlight into energy for growth and reproduction.
How large can the Marasmius oreades grow?
depends on whether you want to know size of the fruiting body or the fairy ring itself (the mycelium). The fruits can reach a couple of inches in diameter for the cap and couple of inches in heights (average in the 1-2inches in both height and width, though usually slightly taller than wide). The fairy rings can reach considerable diameters (10-20ft, or larger) with enough time. Usually, the ring is disturbed or blocked by something before the maximum growth diameter is reached. Most I've seen personally only reach 2-3 ft in diameter, but I've seen a few as large as 5-6 feet across.
