Exploring Cellular Components

What is the primary function of the cell membrane?

• To store genetic information

• To provide structural support to the cell

• To facilitate energy production in the cell

• The primary function of the cell membrane is to control the movement of substances in and out of the cell.

What organelle is known as the powerhouse of the cell?

• Chloroplast

• Ribosome

• Mitochondria

• Nucleus

Explain the role of ribosomes in the cell.

• Ribosomes synthesize proteins by translating mRNA into polypeptides.

• Ribosomes transport nutrients across the cell membrane.

• Ribosomes are responsible for cell division.

• Ribosomes store genetic information for the cell.

What is the function of the Golgi apparatus?

• The Golgi apparatus is responsible for energy production.

• The Golgi apparatus functions to modify, sort, and package proteins and lipids.

• The Golgi apparatus detoxifies harmful substances.

• The Golgi apparatus synthesizes DNA and RNA.

How do lysosomes contribute to cellular function?

• Lysosomes are responsible for protein synthesis.

• Lysosomes store genetic information.

• Lysosomes contribute to cellular function by digesting waste and recycling cellular components.

• Lysosomes produce energy for the cell.

What is the significance of the double membrane in mitochondria?

• The double membrane prevents any metabolic processes from occurring.

• The double membrane is involved in photosynthesis within mitochondria.

• The double membrane allows compartmentalization, enhances ATP production, and regulates metabolic processes.

• The double membrane is solely for structural support and has no functional significance.

Describe the process of cellular respiration in mitochondria.

• Fermentation in the cytoplasm

• Photosynthesis in chloroplasts

• Cellular respiration in mitochondria consists of Glycolysis, the Krebs cycle, and the Electron Transport Chain.

• Protein synthesis in ribosomes

What is contained within the nucleus of a cell?

• Endoplasmic reticulum

• Mitochondria

• Ribosomes

• DNA, nucleoplasm, nucleolus, and proteins

How does the structure of DNA relate to its function?

• DNA structure is irrelevant to its function.

• DNA's function is solely determined by its length.

• The single-stranded nature of DNA allows for better stability.

• The structure of DNA, with its double helix and base pairing, enables stable storage, accurate replication, and encoding of genetic information.

What are the two types of endoplasmic reticulum?

• Flat endoplasmic reticulum

• Cylindrical endoplasmic reticulum

• Rough endoplasmic reticulum and Smooth endoplasmic reticulum

• Circular endoplasmic reticulum
