Exploring Cell Structure and Function

What is the basic unit of life?

• Organ

• Organism

• Cell

• Tissue

Describe the function of the cell membrane.

• The cell membrane is responsible for protein synthesis.

• The cell membrane regulates the movement of substances in and out of the cell.

• The cell membrane acts as a storage unit for nutrients.

• The cell membrane provides energy for cellular processes.

What organelle is responsible for energy production?

• Chloroplast

• Ribosome

• Nucleus

• Mitochondria

Explain the role of ribosomes in a cell.

• Ribosomes store genetic information for the cell.

• Ribosomes transport nutrients across the cell membrane.

• Ribosomes are responsible for cell division.

• Ribosomes synthesize proteins by translating mRNA into polypeptides.

What is the function of the nucleus?

• The nucleus produces energy for the cell.

• The nucleus functions as the control center of the cell, housing DNA and regulating gene expression.

• The nucleus is responsible for protein synthesis.

• The nucleus transports nutrients across the cell membrane.

Identify the structure that provides support to plant cells.

• Cytoplasm

• Cell wall

• Chloroplast

• Cell membrane

What is the difference between prokaryotic and eukaryotic cells?

• Prokaryotic cells lack a nucleus and membrane-bound organelles; eukaryotic cells have both.

• Prokaryotic cells contain membrane-bound organelles while eukaryotic cells do not.

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

• Eukaryotic cells are always smaller than prokaryotic cells.

Describe the function of lysosomes.

• Lysosomes function as the cell's waste disposal system, breaking down and recycling various biomolecules.

• Lysosomes are responsible for protein synthesis in the cell.

• Lysosomes are involved in energy production within the cell.

• Lysosomes store genetic information for the cell.

What role do mitochondria play in cellular respiration?

• Mitochondria store genetic information for the cell.

• Mitochondria are responsible for protein synthesis.

• Mitochondria convert nutrients into ATP during cellular respiration.

• Mitochondria help in the digestion of food particles.

How do chloroplasts contribute to photosynthesis?

• Chloroplasts absorb nutrients from the soil to produce energy.

• Chloroplasts capture light energy and convert carbon dioxide and water into glucose and oxygen during photosynthesis.

• Chloroplasts store energy in the form of starch without using light.

• Chloroplasts are responsible for cellular respiration in plants.
