DENDROLOGY

Detailed explanation-1: -Since bacteria don’t have chloroplasts, photosynthetic pigments are found in their membrane folds. Blue-green algae, often known as cyanobacteria, have chlorophyll and are able to perform oxygenic photosynthesis just like plants. While plants evolve oxygen, other microorganisms do anoxygenic photosynthesis.

Detailed explanation-2: -Within the prokaryotic domain, there are five main groups of bacteria that perform tetrapyrrole-based photosynthesis. They are proteobacteria (also known as purple bacteria), heliobacteria, Chloroflexi (filamentous bacteria also known as green non-sulfur bacteria), Chlorobi (green sulfur bacteria) and cyanobacteria.

Detailed explanation-3: -Some bacteria are able to use a process called photosynthesis to convert energy from sunlight into another form of energy they can use to grow. Within the bacteria, structures known as photosystems are responsible for absorbing light and transferring the energy to other molecules.

Detailed explanation-4: -Cyanobacteria are prokaryotic bacteria that are photosynthetic. They lack organized chloroplasts as present in eukaryotes. Their photosynthetic apparatus is distributed peripherally inside the cytoplasm. The blue-green bacteria do contain chlorophyll a and produce free oxygen as a photosynthesis byproduct.

Detailed explanation-5: -Cyanobacteria are photosynthetic, autotrophic bacteria. They contain chlorophyll similar to plants and also other chromatophores.
