How do cyanobacteria photosynthesize without chloroplasts?
They lack a membrane bound nucleus, chloroplasts, and other organelles found in plants and algae. Instead, cyanobacteria have a double outer cell membrane and folded inner thylakoid membranes that are used in photosynthesis.
How are cyanobacteria photosynthetic?
Cyanobacteria use photosynthetic pigments, such as carotenoids, phycobilins, and various forms of chlorophyll, which absorb energy from light. Unlike heterotrophic prokaryotes, cyanobacteria have internal membranes. These are flattened sacs called thylakoids where photosynthesis is performed.
Do cyanobacteria have chloroplasts and do they carry out photosynthesis?
In plant cells, photosynthesis takes place in the chloroplast, small structures that contain chlorophyll and thylakoids. Cyanobacteria don’t have chloroplasts. Instead, the chlorophyll is stored in thylakoids in their cytoplasm.
Do cyanobacteria have chloroplasts Why or why not?
Like all other prokaryotes, cyanobacteria lack a membrane-bound nucleus, mitochondria, Golgi apparatus, chloroplasts, and endoplasmic reticulum. All of the functions carried out in eukaryotes by these membrane-bound organelles are carried out in prokaryotes by the bacterial cell membrane.
Chloroplasts are one of many types of organelles in the plant cell. They are considered to have evolved from endosymbiotic cyanobacteria. Mitochondria are thought to have come from a similar endosymbiosis event, where an aerobic prokaryote was engulfed.
Do protists have photosynthesis?
Protist cells
Photosynthetic protists such as the various types of algae contain plastids. These organelles serve as the site of photosynthesis (the process of harvesting sunlight to produce nutrients in the form of carbohydrates). The plastids of some protists are similar to those of plants.
Do oscillatoria cells have chloroplasts?

Do cyanobacteria have enzymes?
Cyanobacteria may possess several enzymes that are directly involved in dihydrogen metabolism: nitrogenase(s) catalyzing the production of hydrogen concomitantly with the reduction of dinitrogen to ammonia, an uptake hydrogenase (encoded by hupSL) catalyzing the consumption of hydrogen produced by the nitrogenase, and …
Do protists have chloroplasts?
Protista. Protists are single-celled and usually move by cilia, flagella, or by amoeboid mechanisms. There is usually no cell wall, although some forms may have a cell wall. They have organelles including a nucleus and may have chloroplasts, so some will be green and others won’t be.
Is cyanobacteria autotrophic or heterotrophic?
Cyanobacteria, also known as “blue-green algae,” are a group of free-living photosynthetic bacteria. Cyanobacteria are autotrophic and can obtain their energy through photosynthesis.
Do cyanobacteria have photosynthetic pigments?
The photosynthetic pigments of cyanobacteria include chlorophyll a, β-carotene, zeaxanthin, echinenone, myxoxanthophyll, and other xanthophylls in addition to an array of water soluble chromoproteins, organized in the phycobilisomes.
Why are cyanobacteria not considered plants?
Cyanobacteria are bacteria that can photosynthesize. It’s a producer like a plant, but it’s not a plant in the sense of being part of the plant kingdom or having the features of plant cells.
How do photosynthetic bacteria such as cyanobacteria conduct photosynthesis in the absence of chloroplasts?

How did cyanobacteria turn into chloroplasts?
As can be recounted today from several lines of evidence, this cyanobacterium would have become the chloroplast through endosymbiosis.
Which protist shows photosynthesis?
Photosynthetic Protists
Protists that are capable of photosynthesis include various types of algae, diatoms, dinoflagellates, and euglena. These organisms are often unicellular but can form colonies. They also contain chlorophyll, a pigment which absorbs light energy for photosynthesis.
Is Protista autotrophic or heterotrophic?
Protists get food in many different ways. Some protists are autotrophic and have chloroplasts, others are heterotrophic and ingest food by either absorption or engulfment (phagocytosis). Reproduction in protists varies widely, depending on the species of protist and the environmental conditions.
How did photosynthetic protists become photosynthetic?
Because we know that photosynthesis is a process that plants use, we can define photosynthetic protists as ‘plant-like’ protists that get their nutrients by converting sunlight into energy using photosynthesis. Some examples of exclusively photosynthetic protists include some phytoplankton and unicellular algae.
Why are cyanobacteria called photosynthetic Autotrophs?
Cyanobacteria (blue-green algae) have chlorophyll and do photosynthesis. As they make their own food thus, they are autotrophs.
Are cyanobacteria decomposers?
Green algae and cyanobacteria are found at the beginning of the food chain. They are known as primary producers because they make their own food.
Are cyanobacteria prokaryotes?
Abstract. Cyanobacterial taxonomy developed in the botanical world because Cyanobacteria/Cyanophyta have traditionally been identified as algae. However, they possess a prokaryotic cell structure, and phylogenetically they belong to the Bacteria.
Can Eubacteria do photosynthesis?
Essential components of the photosynthetic apparatus, such as carotenoids, are present in both halobacteria and in eubacteria, including the nonphotosynthetic eubacteria, suggesting that photosynthesis could be a primitive property of both groups.
Are Eubacteria autotrophs or heterotrophs?
Body Structure: Eubacteria are single-celled organisms. Food: Eubacteria are both auto- and heterotrophic. When they are autotrophic, they use both chemical synthesis and photosynthesis.
Are Eubacteria prokaryotes?
Eubacteria are prokaryotic microorganisms consisting of a single cell lacking a nucleus and containing DNA is a single circular chromosome.
How does Anabaena perform photosynthesis?
They perform oxygenic photosynthesis, very similar to that of eukaryotic plants and algae, by utilizing water as a reductant source, consequently producing molecular oxygen.
Do photosynthetic bacteria contain chloroplasts?
Bacteria do not contain membrane-bound organelles such as mitochondria or chloroplasts, as eukaryotes do. However, photosynthetic bacteria, such as cyanobacteria, may be filled with tightly packed folds of their outer membrane.
How do photosynthetic bacteria and cyanobacteria conduct photosynthesis?
The Cyanobacteria and photosynthetic bacteria are prokaryotes. They do not have well defined membrane bound cell organelles, but these organisms have photosynthetic pigments in a membranous form, which are primitive in nature but can trap and use solar energy. So, they can carry out photosynthesis.
Are cyanobacteria heterotrophs?
The Distinctions in Composing Characteristics of Cyanobacteria–Heterotrophic Bacteria Between Two Estuarine Reservoirs. In aquatic ecosystem, Cyanobacteria could release a large number of secondary metabolites during the process of growth, such as DOC and other micro-molecular organics to surroundings.

In what way was the photosynthesis carried out by cyanobacteria different from that of other photosynthetic organisms?
These phycobiliproteins are an important part of the tiny microscopic organisms called cyanobacteria, which carry out photosynthesis in much the same way as land plants do. The only difference is that they use a different set of chemical molecules—cyanobacteria use phycobiliproteins while land plants use Chl.
Where are the photosynthetic pigments located in cyanobacteria?
Phycobilins are water-soluble pigments, and are therefore found in the cytoplasm, or in the stroma of the chloroplast. They occur only in Cyanobacteria and Rhodophyta.

Are protists photosynthetic?
According to Simpson, protists can be photosynthetic or heterotrophs (organisms that seek outside sources of food in the form of organic material). In turn, heterotrophic protists fall into two categories: phagotrophs and osmotrophs.
Are protists decomposers?
Protists include species such as protozoa, algae, and molds. Many protist species are decomposers, meaning they feed on dead organisms to meet their nutritional needs.
Are protists motile or sessile?
Many protists are motile, using structures such as cilia, flagella, or pseudopodia (false feet) to move, while others are sessile. They may be autotrophs, producing their own food from sunlight, or heterotrophs, requiring an outside source of nutrition.
Can prokaryotes be photosynthetic?
Prokaryotic photosynthetic organisms have infoldings of the plasma membrane for chlorophyll attachment and photosynthesis (Figure 1). It is here that organisms like cyanobacteria can carry out photosynthesis. Some prokaryotes can perform photosynthesis. This process occurs in the chloroplast.
How is euglena photosynthetic?
Euglenas create their own food through photosynthesis, the process of absorbing sunlight to synthesize foods from carbon dioxide and water. An eyespot at the front end of the euglena detects light, and its chloroplasts (structures that contain chlorophyll) trap the sunlight, allowing photosynthesis to occur.
