GENERAL HISTOLOGY

Detailed explanation-1: -Membrane-bound organelles such as mitochondria and chloroplasts are not seen in unicellular prokaryotic organisms which belong to the Kingdom Monera . They are absent in Streptococcus which is a species of bacteria.

Detailed explanation-2: -Bacteria do not contain membrane-bound organelles such as mitochondria or chloroplasts, as eukaryotes do. However, photosynthetic bacteria, such as cyanobacteria, may be filled with tightly packed folds of their outer membrane.

Detailed explanation-3: -In prokaryotes, there are no membrane-bound organelles.

Detailed explanation-4: -Mitochondria is a membrane bound cell organelle. Such membrane bound cell organelles are absent in prokaryotic cells like bacteria.

Detailed explanation-5: -The only organelles found in bacterial cells are the chromosome and ribosomes. The function of the chromosome is to hold genetic material. The function of a ribosome is to synthesize protein molecules.
