Kingdom Monera and its Classification
Now today we will study the Kingdom Monera and Archaebacteria. KINGDOM MONERA General characteristics Most of them are prokaryotic and are among the smallest organisms on earth. The nucleus is not well organised .i.e. the nucleus lacks nuclear membrane, nucleoplasm , chromatin fibres an also nucleoli . Cell Lacks membrane bound organelles like mitochondria , chloroplasts ,etc. 70 S ribosomes are present in the cell where S is the sedimentation co-efficient. Photosynthetic pigments are present in the form of chromatophores. The plasma membrane in folds to to form the mesosome which has the respiratory enzymes . The monerans posses cell wall except the mycoplasma and its composed of Peptidoglycan. They reproduce asexually for they lack sexual reproduction. The genetic material consists of a single DNA molecule and not particular pattern is followed while distribution of Genetic material. A process known as Mitosis Accomplishes this. They ...
