Diagram of a bacteria - bacteria labelled diagram

Play the game and learn the diagram of a bacteria

 

bacteria labelled diagramWe all know bacteria as the causes for most diseases humans suffer from. However, bacteria are not all the same and do not cause the same diseases. Biology teaches use that bacteria tend to be unicellular organisms with a peculiar structure. Featuring in this page is an interactive bacteria labelled diagram. It features an annotated diagram with labels to drag and drop at the correct position. This worksheet teaches students the structure of bacteria in a fun way. Students will learn while playing a game. In case you don’t get right the first time, keep trying until you get it right. This game will serve well in a classroom setting. Teachers can also get a printable worksheet on how to label a bacterium on this page. This exercise is for students in 1st, 2nd, 3rd, 4th, 5th, 6th and 7th grades.

Diagram of a bacteria cell structure

A bacteria cell is a simple, single-celled organism that lacks a membrane-bound nucleus and other membrane-bound organelles. Despite their simplicity, bacteria are highly adaptable and can be found in almost every environment on Earth.

The diagram of a bacteria cell typically includes the following parts:

  1. Cell wall: The cell wall is a rigid structure that surrounds and protects the cell. It gives the cell its shape and helps to maintain the shape of the cell.

  2. Cell membrane: The cell membrane is a thin, flexible barrier that surrounds the cell and controls the movement of substances in and out of the cell.

  3. Nucleoid: The nucleoid is a region of the cell where the DNA (genetic material) is found. It is not surrounded by a membrane and is not a true nucleus.

  4. Ribosomes: Ribosomes are small, spherical structures that are found in the cytoplasm. They are the site of protein synthesis in the cell.

  5. Pili: Pili (also called fimbriae) are short, hairlike appendages that are found on the surface of some bacteria. They are involved in adhesion (the ability of the cell to stick to surfaces) and can also be used in DNA transfer during a process called conjugation.

  6. Flagella: Flagella are long, whip-like appendages that some bacteria use for locomotion. They are found on the surface of the cell and are used to move the cell through liquids.

  7. Capsule: Some bacteria produce a thick, slimy layer called a capsule that surrounds the cell. The capsule can help the cell to evade the immune system and can also protect the cell from drying out.
