Question

model 1 - three types of bacterial cells

1. the three bacterial shapes in model 1 are referred to as coccus (sphere), spirillum, and bacillus (rod). label the diagrams in model 1 with the correct descriptions.
2. what is represented by the small dots found in each of the bacteria cells?
3. what is the name of the outermost layer that forms a boundary around the outside of each cell?
4. how is the dna described and what does this mean?

prokaryotic and eukaryotic cells

Explanation:

Step1: Identify bacterial shapes

The spherical - shaped bacterium is coccus, the rod - shaped is bacillus, and the spiral - shaped is spirillum. So, label the top - left circle as coccus, the bottom - left elongated shape as bacillus, and the right - hand spiral shape as spirillum.

Step2: Identify small dots

The small dots in each bacteria cell represent ribosomes. Ribosomes are the sites of protein synthesis in the cell.

Step3: Identify outermost layer

The outermost layer that forms a boundary around the outside of each cell is the cell wall. The cell wall provides structural support and protection to the bacterial cell.

Step4: Describe DNA

The DNA is described as free - floating. This means that in prokaryotic cells (like bacteria), the DNA is not enclosed within a nucleus but is instead found in the cytoplasm in a circular, double - stranded form.

Answer:

1. Top - left circle: coccus; Bottom - left elongated shape: bacillus; Right - hand spiral shape: spirillum
2. Ribosomes
3. Cell wall
4. Described as free - floating. It means the DNA is not enclosed in a nucleus but is in the cytoplasm in a circular, double - stranded form.
