(Using bullet points, write down 3 big ideas that you learned about bacterial cells. Answers must be in complete sentences.
- Bacterial cells are prokaryotic cells, which means they do not have a nucleus. Instead, their genetic material is found in a region called the nucleoid.
- One of the key features of bacterial cells is their cell wall, which provides support and protection. The cell wall is made up of peptidoglycan, a complex molecule unique to bacteria.
- Bacterial cells can have various shapes, such as spherical (cocci), rod-shaped (bacilli), or spiral (spirilla). These shapes are determined by the arrangement of their cell wall and cytoskeleton components.
- Bacterial cells are prokaryotic cells that lack a nucleus and membrane-bound organelles. They have a simple structure with a cell wall, cell membrane, and cytoplasm.
- Bacterial cells can take on various shapes, including a rod-like shape called bacilli, a spherical shape called cocci, and a spiral shape called spirilla.
- Bacterial cells have several external structures called appendages, such as flagella, pili, and capsules, that aid in their movement, attachment to surfaces, and protection.
