Exploring Cell Structure and Function

What is the basic unit of life?

• Cell

• Tissue

• Atom

• Organism

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 stores genetic information.

• The cell membrane provides energy for cellular processes.

What organelle is known as the powerhouse of the cell?

• Ribosome

• Mitochondria

• Chloroplast

• Nucleus

What is the role of ribosomes in a cell?

• Ribosomes generate energy for cellular processes.

• Ribosomes store genetic information in a cell.

• Ribosomes synthesize proteins in a cell.

• Ribosomes transport nutrients across the cell membrane.

Explain the difference between prokaryotic and eukaryotic cells.

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

• Prokaryotic cells lack a nucleus and organelles, while eukaryotic cells have a nucleus and organelles.

• Prokaryotic cells have a nucleus, while eukaryotic cells do not.

• Eukaryotic cells are always smaller than prokaryotic cells.

What is the function of the endoplasmic reticulum?

• The endoplasmic reticulum stores genetic material.

• The endoplasmic reticulum transports oxygen in the blood.

• The endoplasmic reticulum is responsible for energy production.

• The endoplasmic reticulum synthesizes proteins and lipids.

How do lysosomes contribute to cellular function?

• Lysosomes are responsible for protein synthesis.

• Lysosomes store genetic information.

• Lysosomes produce energy for the cell.

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

What is the significance of the Golgi apparatus?

• The Golgi apparatus is responsible for DNA replication.

• The Golgi apparatus is significant for modifying, sorting, and packaging proteins and lipids for secretion or delivery to other organelles.

• The Golgi apparatus is involved in the synthesis of ribosomes.

• The Golgi apparatus generates ATP for energy production.

Describe the structure and function of the nucleus.

• The nucleus is a membrane-bound organelle that contains DNA, regulates gene expression, and is involved in cell division.

• The nucleus is a fluid-filled structure that stores nutrients.

• The nucleus is a rigid structure that protects the cell from external damage.

• The nucleus is responsible for energy production in the cell.

What role do mitochondria play in cellular respiration?

• Mitochondria convert glucose and oxygen into ATP during cellular respiration.

• Mitochondria produce carbon dioxide as a waste product of cellular respiration.

• Mitochondria store genetic information for the cell.

• Mitochondria are responsible for photosynthesis in plants.
