Difference between bacterial cell and animal cell

We discus about the bacterial cell and animal cell with plant cell. The cell is the basic functional and structural unit of life. It plays a vital role in all biological activities and includes membrane-bound organelles, which participate in several specialized individual functions to keep the cell alive and active.

The cell was first observed and discovered by the English natural philosopher Robert Hooke in the year 1665. The word cell originates from Latin, which means “small room.”

Depending on the presence of the nucleus and other cell organelles attached to the membrane, the cell is further classified into prokaryotic, eukaryotic, plant and animal cells .

What are bacterial cells ? bacterial cell and animal cell

Bacteria are living single-celled organisms that have grouped into the prokaryotic cell, as these organisms lack a few membrane-bound organelles and the nucleus, which is considered one of the most important cell organelles.

According to the theory of evolution, bacteria were the first organisms to evolve on earth and therefore this group of living organisms is considered one of the oldest forms of life on earth.

What are plant cells? bacterial cell and animal cell

Plant cells are eukaryotic cells that vary in several fundamental factors of an animal cell. Similar to the animal cell, the plant cell comprises the nucleus and other membrane-bound cell organelles.

What are animal cells? bacterial cell and animal cell

Animal cells are eukaryotic cells that contain a membrane-bound nucleus. They differ from plant cells in several fundamental factors. These cells lack cell walls, plastids, and other cell organelles.

This was a brief introduction to plant, animal, and bacterial cells. Apart from this, there are many other facts that prove their differences.

Some key differences between plant, animal, and bacterial cells are listed below in a tabular column.
