(Using bullet points, write down 2-3 big ideas that you learned about bacterial cells. Answers must be in complete sentences.
- Bacterial cells are prokaryotic cells, meaning they lack a true nucleus and other membrane-bound organelles. Instead, their genetic material is located in a region called the nucleoid, which is not enclosed by a membrane.
- Bacterial cells can have different shapes, such as rod-shaped (bacillus), spherical (cocci), or spiral (spirilla). These cellular shapes can influence their ability to move, adhere to surfaces, or interact with other cells in their environment.
- Bacterial cells are prokaryotic cells, meaning they lack a nucleus and membrane-bound organelles. They have a simpler internal structure compared to eukaryotic cells found in humans and other organisms.
- Bacterial cells have a cell wall made of peptidoglycan, which provides support and protection. This cell wall is responsible for the shape of the bacteria (e.g., rod-shaped, spherical), and it helps differentiate different types of bacteria.
- Bacterial cells can have additional structures such as a flagellum for movement, pili for attachment, and a capsule for protection. These structures allow bacteria to survive and thrive in different environments.
