The Genus bacterium was a taxon described in 1828 by Christian Gottfried Ehrenberg. - The type of species was later changed from bacterium triloculare to bacterium coli, now Escherichia coli as it was lost. - In 1676 Antonie Van Leeuwenhoek first observed bacteria through a microscope called then animalcules.

The genetic material of bacteria is present as:
1 spherosome
2 genophore
3 lomasomes
4 mesosome
Explanation:
The genetic material of bacteria is present as genophore. It refers to chromosome equivalent in prokaryotes, virus and semi- autonomous organelles that serves as heredity material it consist of nucleic acid. DNA or RNA but lack histone protein. - Many eukaryotes (such as plants and animals) carry genophores in organelles such as mitochondria and chloroplast. These organelles are very similar to true prokaryotes.

The site of photosynthesis in blue-green algae is
1 Chromatophores
2 Mitochondria
3 Chloroplast
4 Root hair
Explanation:
Cynobacteria or blue-green algae are prokaryotes and hence lack membrane bound organelles such as chloroplast. They possess chromatophores insted of chloroplast as the site of photosynthesis. - Chromatophore are pigment - containing vesicles that are found in cell cytoplasm and play vital role in photosynthesis.

Which of the following characters belongs to the Kingdom Monera?
1 Eukaryotic
2 Heterotrophic
3 Multicellular
4 Presence of cell walls made of cellulose
5 Presence of nuclear membrane
Explanation:
Heterotrophic organisms are those organism which can not prepare their own food through the process of photosynthesis and they depend on autotrophs for nutrition directly or indirectly. - All animals and non-photosynthetic plants are classified as heterotrophs since they are unable to prepare food.
