Biology Goal 1 Review

Some organelles have their own DNA

that is distinct from the cell’s nuclear

DNA. This is true of which organelle?

• cell wall

• mitochondrion

• plasma membrane

• vacuole

Placing wilted lettuce in cold water will make it crisp again. Which statement best describes what happens to restore the lettuce to its original condition?

• Water left the lettuce cells by diffusion.

• Water entered the cells of the lettuce by osmosis.

• Osmosis caused salts to enter the lettuce cells.

• Salts in the leaf caused water to leave the cells.

What can be used to distinguish between eukaryotic and prokaryotic cells?

• Only eukaryotic cells come from preexisting cells.

• Only prokaryotic cells are the smallest unit of living organisms.

• Only prokaryotic cells contain ribosomes.

• Only eukaryotic cells contain membrane-bound organelles.

Nerve cells and bone cells are specialized cells that descend from the same single cell (fertilized egg). Which statement best explains how each type of cell results in a different structure with a specialized function?

• Nerve cells and bone cells begin with the same structure; however, bone cells harden over time.

• Nerve cells and bone cells receive different DNA that determines the structure and function that each will perform.

• Nerve cells and bone cells receive the same DNA; however, only specific parts of the DNA are activated in each cell.

• Nerve cells and bone cells receive the same DNA; however, bone cells receive more to make the protective outer covering.

The solute molecules in this beaker are separated by a selectively permeable membrane, which they can cross. What results would be expected after 24 hours?

• More solute molecules in side 2 than side 1.

• There would be an equal number of solute molecules in both sides.

• The water level on side 2 would rise.

• The water level on side 1 would rise.

Cell cycle checkpoints are proteins that monitor and regulate the progress of the cell cycle in eukaryotic cells. Which statement best describes what would most likely happen if a cell is permitted to progress to mitosis without the preparation stage of interphase?

• The new cells would have all of the organelles except the nucleus.

• The new cells would have all of the organelles except the mitochondria.

• The number of chromosomes in the daughter cells would be the same as the number of chromosomes in the parent cell.

• The number of chromosomes in the daughter cells would be different from the number of chromosomes in the parent cell.

A single-celled organism is placed in fresh water. The contractile vacuole pumps excess water out of the cell. How does this action help the organism to survive?

• It helps the organism maintain a stable internal environment.

• It helps the organism communicate with other cells.

• It helps the organism reproduce.

• It helps the organism convert energy.
