Prokaryotes are organism whose cell lack a nucleus and other organelles like membrane bounded organelles as Mitochondria, Golgi body, Endoplasmic reticulum. It is unicellular organism which has incipient nucleus and $70 \mathrm{~S}$ type of Ribosomes.

When there is bunch of flagella on one side, the bacteria are known as
1 lophotrichous
2 amphitrichous
3 peritrichous
4 none of these
Explanation:
When a group of flagella is present at an end only is called lophotrichous Eg-Spirillum volutans.CC(=O)C1CCCCC1

Pigment-containing membranous extensions in some cyanobacteria are:
1 Chromatophores
2 Heterocysts
3 Basal bodies
4 Pneumatophores
Explanation:
: Cyanobacteria have chromatophores a unique compartment in their cytoplasm. Amphibians, Fish, Reptiles, and Cephalopods all have chromatophore, which are pigment containing and light reflecting cells.

Besides paddy fields, cyanobacteria are also found inside vegetative part of:
1 Psilotum
2 Pinus
3 Cycas
4 Equisetum
Explanation:
Cycas are considered ancient plants. They are palm-like trees. The trunk of the plant is columnar and aerial in nature. The roots show negative geotropism. So, these are called coralloid roots that have nitrogen-fixing bacteria. Also, these roots are photosynthetic due to the presence of photosynthetic bacteria. This property is due to the presence of cyanobacteria.

Barophilic prokaryotes -
1 Grow slowly in highly alkaline frozen lakes at high altitudes
2 Grow and multiply in very deep marine sediments
3 Readily grow and divide in sea water enriched in any soluble salt of barium
4 Occur in water containing high concentrations of barium hydroxide
Explanation:
Barophilic prokaryotes, also known as barophile, is a type of organism which can grow and exists at high pressure zone. e.g. deep sea bacteria and archaebacteria. They can grow and multiply is very deep sea sediments.
