Cell Organelles and Their Functions Video Questions

What is the primary component of the cell membrane and its main function?

• Proteins, to transport substances

• Phospholipid bilayer, to contain cell fluid

• Carbohydrates, for cell recognition

• Cholesterol, to maintain fluidity

What is chromatin, and what process occurs in the nucleus to create mRNA from DNA?

• Condensed chromosomes; translation

• Long, curvy strands of DNA; transcription

• Ribosomes; protein synthesis

• Nuclear membrane; replication

What is the function of a ribosome, and what is the process called where it reads mRNA to build a protein?

• To make ribosomes; transcription

• To modify proteins; glycosylation

• To translate mRNA into protein; translation

• To store genetic information; replication

Why does the Rough Endoplasmic Reticulum (Rough ER) appear "rough" under a microscope, and what is one of its key functions?

• It has a bumpy surface due to attached ribosomes; initial protein folding

• It synthesizes lipids and carbohydrates; detoxification

• It contains chromatin; DNA transcription

• It packages and ships proteins; cellular respiration

What is a primary function of the rough endoplasmic reticulum (Rough ER) in a cell?

• Synthesizing lipids and carbohydrates

• Converting food energy into ATP

• Modifying and folding proteins

• Storing genetic material

Which organelle is responsible for further modifying, sorting, and packaging proteins into vesicles for transport?

• Nucleus

• Ribosome

• Golgi Apparatus

• Smooth Endoplasmic Reticulum

Which organelle is characterized by its smooth appearance due to the absence of ribosomes and is involved in the synthesis of lipids and carbohydrates?

• Rough Endoplasmic Reticulum

• Golgi Apparatus

• Smooth Endoplasmic Reticulum

• Lysosome

What is the primary function of the mitochondria in a cell?

• Breaking down cellular waste

• Storing genetic material

• Producing ATP from food energy

• Synthesizing proteins

What is the primary function of peroxisomes in a cell?

• Breaking down proteins

• Storing chemicals

• Neutralizing toxic substances

• Producing energy

Which statement accurately describes vacuoles in animal and plant cells?

• Animal cells have large vacuoles, while plant cells have small ones.

• Both animal and plant cells have large vacuoles for storage.

• Plant cells typically have large vacuoles, while most animal cells have small ones for storage.

• Vacuoles are primarily involved in protein synthesis in both cell types.
