Explain how the structure of the cell membrane contributes to its function.

• The rigid structure provides support and protection.

• The fluid mosaic model allows selective permeability.

• The thick layer prevents all substances from entering.

• The solid structure allows for easy transport of materials.

Describe the role of ribosomes in a cell.

• They store genetic information.

• They synthesize proteins.

• They break down waste materials.

• They transport substances across the cell membrane.

Which of the following best describes the function of the nucleolus within the nucleus?

• It stores DNA.

• It synthesizes ribosomal RNA.

• It regulates cell division.

• It modifies proteins.

Compare and contrast the functions of the smooth and rough endoplasmic reticulum.

• Both synthesize proteins; the rough ER also detoxifies chemicals.

• The smooth ER synthesizes lipids; the rough ER synthesizes proteins.

• Both store calcium ions; the smooth ER also synthesizes proteins.

• The rough ER detoxifies chemicals; the smooth ER stores genetic material.

What is the primary function of the mitochondria in eukaryotic cells?

• Photosynthesis

• Protein synthesis

• Energy production

• Lipid storage

A cell is observed to have a large number of lysosomes. What might this indicate about the cell's function?

• It is involved in energy production.

• It is involved in protein synthesis.

• It is involved in waste processing and recycling.

• It is involved in lipid storage.
