Worked practice questions

Schleiden and Schwann concluded that every living thing is built from one or more:

  1. Cells
  2. Crops
  3. Curls
  4. Coils
Show answer and solution

Correct answer: A. Cells

1. They studied plant and animal tissues side by side. 2. Both turned out to be built from the same basic unit. 3. That unit is the cell. _Source: OpenStax Concepts of Biology, Chapter 3, Cell Structure and Function._

A biologist sorts every cell she meets into just two broad categories: eukaryotic and:

  1. Progressive
  2. Prokaryotic
  3. Protective
  4. Productive
Show answer and solution

Correct answer: B. Prokaryotic

1. The split turns on whether a true nucleus is present. 2. Cells with one are eukaryotic. 3. Cells without one are prokaryotic. _Source: OpenStax Concepts of Biology, Chapter 3, Cell Structure and Function._

A bacterium has no nucleus and no membrane-bound organelles at all. It is therefore:

  1. Prokaryotic
  2. Protective
  3. Productive
  4. Progressive
Show answer and solution

Correct answer: A. Prokaryotic

1. The defining absence here is the enclosed nucleus. 2. Bacteria keep their DNA loose in the cytoplasm. 3. The cell is prokaryotic. _Source: OpenStax Concepts of Biology, Chapter 3, Cell Structure and Function._
