U4 Quizizz Prokaryotic and Eukaryotic Cells POGIL

The three bacterial shapes in Model 1 are referred to as coccus as A (sphere), spirillum as B, and bacillus as C (rod). Label the diagrams in Model 1 with the correct descriptions. A - B - or C

What is represented by the small dots found in each of the bacteria cells?

• Mitochondria
• Nucleus
• Endoplasmic reticulum
• Ribosomes

What is the name of the outermost layer that forms a boundary around the outside of each cell?

• Nucleus wall
• Cytoplasm barrier
• Cell shield
• Cell membrane

How is the DNA described and what does this mean?

Answer explanation

The DNA is free floating which means that in bacterial cells (prokaryotic cells) the DNA floats in the cytoplasm and not in an enclosed nucleus.

All the internal structures in cells are suspended (floating) in what substance?

• cytoplasm
• ribosomes
• mitochondria
• nucleus

One of the bacteria in Model 1 has a tail-like structure what might be the purpose of this structure?

• The tail-like structure, called a flagellum, helps the bacteria move and navigate.
• The tail-like structure is used for photosynthesis or other useful energy like functions.

• The tail-like structure is a form of defense against predators and other microbial functions and predators.

• The tail-like structure is a storage compartment for nutrients

One of the bacteria in Model 1 has a tail-like structure, what might you infer about the absence of this structure in the other two bacteria cells?

• The tail-like structure is not present in all bacteria cells.
• The tail-like structure is present in all bacteria cells.
• The tail-like structure is a common feature in bacteria cells.

Looking at Model 2, list at least three structural differences (other than shape) between an animal cell and a plant cell.

Where do you find the DNA in each cell in Model 2?

• cytoplasm
• mitochondria
• cell membrane
• nucleus

Do both cells in Model 2 have a nucleus?

• Yes

• No
