Why does thylakoid membranes of chloroplasts resemble those of cyanobacteria?
Thylakoid membranes of chloroplasts resemble those of cyanobacteria because chloroplasts are believed to have evolved from endosymbiotic cyanobacteria. During evolution, the cyanobacteria that were engulfed by a host cell eventually became mutually beneficial, leading to the development of chloroplasts. The structural similarity between the thylakoid membranes of chloroplasts and cyanobacteria is a remnant of this evolutionary relationship.
Do nitrogen fixing bacteria have chloroplasts?
No bacteria have chloroplasts. Plants have chloroplasts. Chloroplasts were originally cyanobacteria -- they are the results of an endosymbiosis between a cyanobacterium and a eukaryote.
Which organism does not carry out photosynthesis?
Most photosynthetic organisms that do not contain chloroplasts are bacteria. Some examples would be green sulfur and non sulfur bacteria which use chlorosomes. Chlorosomes contain light harvesting pigments known as bacteriochlorophylls. Cyanobacteria do not contain chloroplasts but use chlorophyll A and phycobilin photosynthetic pigments.
What membrane bound organelle associated with photosynthesis is absent in cyanobacteria?
Cyanobacteria lack chloroplasts, which are membrane-bound organelles associated with photosynthesis found in eukaryotic cells, such as plants and algae. Instead, cyanobacteria perform photosynthesis using thylakoid membranes that are integrated into their cell membrane. These thylakoids contain chlorophyll and other pigments necessary for capturing light energy, allowing cyanobacteria to conduct photosynthesis without the need for chloroplasts.
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.

No bacteria have chloroplasts. Plants have chloroplasts. Chloroplasts were originally cyanobacteria -- they are the results of an endosymbiosis between a cyanobacterium and a eukaryote.
Where did chloroplasts originate from?
Chloroplasts are believed to have originated from ancient cyanobacteria through a process called endosymbiosis.
The chloroplasts in eukaryotes closely resemble?
The chloroplasts in eukaryotes closely resemble cyanobacteria, as first noted by French scientist Andreas Schimper. Cyanobacteria are bacteria that produce energy for themselves through photosynthesis.
Which organism does not carry out photosynthesis?
Most photosynthetic organisms that do not contain chloroplasts are bacteria. Some examples would be green sulfur and non sulfur bacteria which use chlorosomes. Chlorosomes contain light harvesting pigments known as bacteriochlorophylls. Cyanobacteria do not contain chloroplasts but use chlorophyll A and phycobilin photosynthetic pigments.
What organisms in addition to plants do photosynthesis?
cyanobacteria (the probable ancestors of the chloroplasts in plant cells)
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 membrane bound organelle associated with photosynthesis is absent in cyanobacteria?

These thylakoids contain chlorophyll and other pigments necessary for capturing light energy, allowing cyanobacteria to conduct photosynthesis without the need for chloroplasts.
What photosynthetic organism does not have a chloroplast?
Cyanobacteria, also called blue-green algae, are bacteria that photosynthesize but do not have chloroplasts.
How is cyanobacteria like algae and land plants?
Although cyanobacteria do not have chloroplasts, they do have thylakoid membrane, where photosynthesis occur.
What is the sequence that represents the correct order of development of chloroplasts of modern plants from their primitive ancestors?
Cyanobacteria > Red Algae > Green Algae > Land Plants
Is cyanobacteria anscestors of schloroplast?
Although the initial suggestion that cyanobacteria are the ancestors of chloroplasts was greeted with skepticism, the idea is now widely accepted. It was suggested the chloroplast lineage arose at the onset of diversification of the cyanobacterial lineage.
