photosynthetic or other pigments are expressed in several protozoan species and are thus used to color them. protozoan species produce a wide variety of life stages, depending on the species. The different stages of life, as well as the species at each stage, can sometimes be mistaken for entirely different creatures.
What are the similarities between protozoa and algae?
cyanobacteria is in the domain bacteria, protozoa is in the domain eukarya, and algae is in the domain eukarya algae and plants both have organelles known as chloroplasts. the number of membranes around the chloroplasts of algae and plants are different protozoa can move by using structures that will beat and propel them.
How do protozoa move?
protozoa can move by using structures that will beat and propel them. theses are known as flagella and cilia. protozoa can also move by extending cytoplasmic extensions known as pseudopodia, or they can glide what organisms were formerly known as blue green algae? why are these not actually algae?
Which domains are algae protozoa and cyanobacteria classified?
in which domains are algae, protozoa, and cyanobacteria classified? cyanobacteria is in the domain bacteria, protozoa is in the domain eukarya, and algae is in the domain eukarya name one difference and one similarity between algae and plants

Do protozoa have photosynthetic?
CLASSES OF PROTOZOA They do not photosynthesize, rather being chemoheterotrophic like animals. This means that they use chemicals for energy production and they get their carbon from the same compounds, e.g. sugar.
Do protozoa contain chloroplasts?
The term "protozoa" was popular in the 20th century but has now become obsolete. The group includes members of the Kingdom Protista that do not have chloroplasts and therefore have no color.
Does protozoa possess chlorophyll?
A protozoa is found to contain chlorophyll.
What protozoa has chloroplast?
Euglena sp. The species Euglena gracilis has been used extensively in the laboratory as a model organism. Most species of Euglena have photosynthesizing chloroplasts within the body of the cell, which enable them to feed by autotrophy, like plants.
What are 5 characteristics of protozoa?
They are parasites or free-living.They have flagella for locomotion.Their body is covered by a cuticle or pellicle.Freshwater forms have a contractile vacuole.Reproduction is by binary fission (longitudinal division)Examples: Trypanosoma, Trichomonas, Giardia, Leishmania, etc.
How are protozoa and bacteria different?
Protozoa (pronounced: pro-toe-ZO-uh) are one-celled organisms, like bacteria. But they are bigger than bacteria and contain a nucleus and other cell structures, making them more similar to plant and animal cells.
Which is the only protozoa which have chlorophyll?
phytoflagellate, any member of a group of flagellate protozoans that have many characteristics in common with typical algae. Some contain the pigment chlorophyll and various accessory pigments and have a photosynthetic type of nutrition, although many organisms included in this group exhibit heterotrophy or mixotrophy.
What is unique about protozoans?
Protozoa are notable for their ability to move independently, a characteristic found in the majority of species. They usually lack the capability for photosynthesis, although the genus Euglena is renowned for motility as well as photosynthesis (and is therefore considered both an alga and a protozoan).
Which of the following characteristics is not true about protozoa?
Answer and Explanation: The option that is NOT a characteristic of protozoans is c) reproduce sexually via binary fission. Protozoans do reproduce via binary fission, but it is an asexual method of reproduction. Protozoans are protists, which is a kingdom of organisms that are eukaryotic but are mainly unicellular.
Which protozoa can photosynthesis and why?
Euglena, a single-celled eukaryote, contains holophytic nutrition. They are holophytic because they have chloroplasts, which are used for photosynthesis.
Do all protists have chlorophyll?
The autotrophs such as plant-like protists (algae) possess a chloroplast. This organelle is missing in most heterotrophs' protists, such as protozoa, slime, and water molds. However, some protists, such as Plasmodium, possess a non-functional chloroplast, which is non-photosynthetic.
Is paramecium photosynthetic?
The green Paramecium has a higher compensationpoint of photosynthesis (4000-5000 lux) than the isolated alga (200-400 lux). 3. Green paramecia consume less oxygen in darkness than colourless organisms but more than the isolated algae.
Which organelle is not found in most protozoa?
Chloroplast is the organelle that provides certain living organisms the ability to perform photosynthesis. It is found in algae but absent in microorganisms like protozoa and fungi.
Which structure is not found in protozoa?
Historically, protozoans were regarded as "one-celled animals", because they often possess animal-like behaviours, such as motility and predation, and lack a cell wall, as found in plants and many algae.
Does bacteria have a chloroplast?
Bacteria do not contain membrane-bound organelles such as mitochondria or chloroplasts, as eukaryotes do.
Which eukaryotes contain chloroplasts?
All green plants and algae of eukaryotes contain chloroplasts. These are organelles that contain the photosynthetic pigment, and chlorophyll, and thus are crucial for the green plants.
