GENERAL HISTOLOGY

Detailed explanation-1: -Because bacteria are prokaryotic, they do not have a nucleus and no membrane-bound organelles. In contrast, plants and animals are made up of eukaryotic cells, which means they have a nucleus and membrane-bound organelles like mitochondria or golgi apparatus.

Detailed explanation-2: -Bacteria cells are very different from animal, plant or fungal cells. They don’t have organelles such as nuclei, mitochondria or chloroplasts. Although they do have ribosomes and a cell wall, these are both different in structure to the ribosomes and cell walls in the cells above.

Detailed explanation-3: -A bacteria is made up of a single cell. Such organisms are called single-celled organisms.

Detailed explanation-4: -Antonie Van Leeuwenhoek first observed bacteria in the year 1676, and called them ‘animalcules’ (from Latin ‘animalculum’ meaning tiny animal).

Detailed explanation-5: -Bacteria are individual living cells. Bacteria cells are similar to your cells in many ways; yet, they also have distinct differences. Bacteria have many unique adaptations allowing them to live in many different environments.
