What structures are built by cyanobacteria?
Cyanobacteria can form structures called stromatolites, which are layered formations of sediment and trapped microorganisms. They also build specialized cells called heterocysts to fix nitrogen in environments with low nitrogen levels. Additionally, cyanobacteria can create sheaths and filaments to protect themselves and aid in nutrient absorption.
The prokaryotic cells that built stromatolites are classified as?
The prokaryotic cells that built stromatolites are classified as cyanobacteria. Cyanobacteria are photosynthetic bacteria that played a crucial role in the formation of stromatolites, which are layered structures formed by the trapping and binding of sediment by microbial communities.
How do cyanobacteria reproduce?
Cyanobacteria reproduce asexually through binary fission, where a single cell divides into two daughter cells. They can also reproduce through fragmentation, where a portion of the cyanobacteria breaks off and forms a new individual. In addition, some cyanobacteria can form specialized cells called akinetes or heterocysts that can survive harsh conditions and later develop into new cyanobacteria.
Is cyanobacteria a prokaryote or eukaryote?
Cyanobacteria are prokaryotes. They lack a membrane-bound nucleus and other organelles commonly found in eukaryotic cells.
What organelle present in alga and plant cell is lacking in cyanobacteria cells?
Cyanobacteria lack chloroplasts, which are organelles found in alga and plant cells responsible for photosynthesis. Instead, cyanobacteria perform photosynthesis using thylakoid membranes within their cytoplasm. This fundamental difference highlights the distinction between eukaryotic organisms, like plants and algae, which possess membrane-bound organelles, and prokaryotic organisms like cyanobacteria.

Heterocyst is found in what organism?
Heterocysts are specialized cells found in cyanobacteria, particularly in filamentous species like Anabaena and Nostoc. These cells are involved in nitrogen fixation, converting atmospheric nitrogen into a form that can be utilized by the organism.
What are producer bacteria that contain the green pigment chlorophyll called?
cyanobacteria contains a green pigment chlorophyll

What refers to organelles which conduct photosynthesis and closely resemble cyanobacteria.?
The organelles that conduct photosynthesis and closely resemble cyanobacteria are called chloroplasts. These organelles are found in the cells of plants and algae, and they contain chlorophyll, which captures light energy to convert carbon dioxide and water into glucose and oxygen through the process of photosynthesis. Chloroplasts are thought to have originated from an endosymbiotic relationship with ancestral cyanobacteria.
Are also called blue-green bacteria?
It's called Cyanobacteria
What is the likely origin of chloroplast?
Chloroplasts likely originated from a type of bacteria called cyanobacteria through a process called endosymbiosis. This is when one organism lives inside another and both benefit from the relationship. Over time, the cyanobacteria evolved into chloroplasts within plant cells, providing them with the ability to photosynthesize and produce energy.
Are chloroplasts only found in animal cells?
No, chloroplasts are only found in plant cells and in some bacterical cells such as cyanobacteria. They are where photosynthesis takes place.
What kingdom does cyanobacteria belongs to?
"Bacteria" refers to a whole domain of organisms, which is a classificational level above kingdom. The domain is called "Bacteria", and it contains several kingdoms of bacteria. Cyanobacteria are their own kingdom, generally called "Cyanobacteria" which is part of Archaebacteria.
