Exploring Cell Organelles

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

• To transport nutrients across the cell membrane

• To store and protect the cell's genetic material (DNA) and control cellular activities.

• To produce energy for the cell

• To synthesize proteins for cellular functions

How do mitochondria contribute to cellular energy production?

• Mitochondria break down fatty acids into carbohydrates.

• Mitochondria produce ATP through cellular respiration.

• Mitochondria synthesize proteins for cellular functions.

• Mitochondria store glucose for energy.

Describe the role of chloroplasts in plant cells.

• Chloroplasts enable photosynthesis, converting sunlight into energy and producing oxygen.

• Chloroplasts store water for plant cells.

• Chloroplasts are responsible for cellular respiration.

• Chloroplasts help in the absorption of nutrients from the soil.

What is the function of the cell membrane?

• The cell membrane stores genetic information.

• The cell membrane is responsible for protein synthesis.

• The cell membrane generates energy for the cell.

• The cell membrane controls the passage of substances and protects the cell.

How do lysosomes aid in cellular digestion?

• Lysosomes synthesize DNA for cell replication.

• Lysosomes transport proteins to the cell membrane.

• Lysosomes aid in cellular digestion by using enzymes to break down waste and cellular debris.

• Lysosomes store nutrients for cellular energy.

What is the significance of the cytoplasm in a cell?

• The cytoplasm is primarily responsible for DNA replication.

• The cytoplasm serves as the cell's energy source.

• The cytoplasm is where the cell's nucleus is located.

• The cytoplasm is significant for maintaining cell structure and transporting materials.

Explain the function of vacuoles in plant cells.

• Vacuoles store water and sugar and help the plant keep its shape.

• Vacuoles help in the process of cellular respiration.

• Vacuoles are primarily involved in protein synthesis in plant cells.

• Vacuoles are responsible for photosynthesis in plant cells.

What distinguishes eukaryotic cells from prokaryotic cells?

• Eukaryotic cells are smaller than prokaryotic cells.

• Prokaryotic cells have a nucleus and eukaryotic cells do not.

• Eukaryotic cells lack DNA while prokaryotic cells contain it.

• Eukaryotic cells have a nucleus and membrane-bound organelles, while prokaryotic cells do not.

How does the structure of a cell wall benefit plant cells?

• The cell wall allows for rapid nutrient absorption.

• The cell wall is primarily responsible for photosynthesis.

• The cell wall helps in the movement of water and nutrients between cells.

• The structure of a cell wall benefits plant cells by providing support, maintaining shape, prevents water loss, and helps in protection.

Why are mitochondria often referred to as the powerhouse of the cell?

• Mitochondria are responsible for protein synthesis.

• Mitochondria are referred to as the powerhouse of the cell because they generate ATP, the main energy source for cellular activities.

• Mitochondria store genetic information for the cell.

• Mitochondria are involved in detoxifying harmful substances.
