Unit 4 Review

Using a light microscope, a student identified the following characteristics of four organisms found in a sample of pond water.

Based on the observations of the student, which organisms most likely belong to the taxonomic group for bacteria?

• Organisms 1 and 2

• Organisms 3 and 4

• Organisms 1 and 4

• Organisms 2 and 3

Four different types of cells are shown.

Which characteristic is shared by all four cells?

• A mechanism for transforming sunlight into energy

• Self-locomotion

• Membrane-bound organelles that transport substances

• Genetic material composed of DNA

Which of these best completes this concept map?

• an animal cell

• a prokaryotic cell

• a virus

• a plant cell

Where is DNA found in a Eukaryotic cell?

• in the nucleus

• in the cell wall

• in the vacuole

• in the mitochondria

The picture above shows a Mexican walking fish and a type of green algea. Though very different, these two organisms —

• live in water, because they are prokaryotic.
• have green coloring, because they are eukaryotic.
• use carbon dioxide, because they are prokaryotic.
• have cells with nuclei, because they are eukaryotic.

What do viruses have in common with living cells? They both...

• store genetic information
• have chloroplasts
• use glucose for cellular respiration
• have endoplasmic reticulum

What do viruses need to reproduce?

• they need genetic material
• They need a host cell
• They need  bacteria
• They need insulin

What is the first step of the virus reproduction cycle?

• The viruses genetic material (DNA) starts to take over the functions of the cell
• The host cell bursts open, releasing the new viruses
• The virus injects its genetic material into the cell
• A virus attaches to the surface of a host cell
