Tough Cell Biology

What is the function of the Golgi apparatus in a cell?

• Stores genetic information

• Produces energy for the cell

• Regulates cell division

• Processes, sorts, and packages proteins and lipids

Explain the process of endocytosis and its significance in cell biology.

• Endocytosis is only important for waste removal in cells.

• Endocytosis does not involve the formation of vesicles.

• Endocytosis is the process of releasing molecules from the cell membrane.

• Endocytosis is the cellular process of absorbing molecules by engulfing them, forming vesicles from the cell membrane. It is essential for nutrient uptake, signaling regulation, and membrane composition control.

What are the differences between prokaryotic and eukaryotic cells?

• Eukaryotic cells lack a nucleus and membrane-bound organelles.

• Prokaryotic cells have a nucleus and membrane-bound organelles.

• The main differences are the presence of a nucleus and membrane-bound organelles in eukaryotic cells, which prokaryotic cells lack.

• Prokaryotic cells are larger in size compared to eukaryotic cells.

Describe the structure and function of mitochondria in a cell.

• Mitochondria have no specific function in a cell.

• Mitochondria are single-membrane-bound organelles responsible for photosynthesis.

• Mitochondria are part of the endoplasmic reticulum.

• Mitochondria are double-membrane-bound organelles responsible for producing ATP through cellular respiration.

What is the role of lysosomes in cellular function?

• Lysosomes are responsible for energy production in cells.

• Lysosomes regulate cell communication and signaling.

• Lysosomes aid in cell division and replication.

• Lysosomes function in cellular digestion and waste removal.

Discuss the importance of the cell membrane in maintaining cell homeostasis.

• The cell membrane is only important for protecting the cell from physical damage.

• The cell membrane has no role in maintaining cell homeostasis.

• The cell membrane is primarily responsible for energy production within the cell.

• The cell membrane is important for maintaining cell homeostasis by controlling the movement of substances.

Explain the concept of cell signaling and its impact on cellular processes.

• Cell signaling plays a crucial role in regulating cellular processes and maintaining homeostasis within an organism.

• Cell signaling is a rare occurrence in organisms

• Cell signaling only affects non-essential cellular functions

• Cell signaling has no impact on cellular processes

What is the significance of the cytoskeleton in cell biology?

• The cytoskeleton is essential for maintaining cell shape, cell division, cell movement, and intracellular transport.

• The cytoskeleton is not important for maintaining cell shape.

• The cytoskeleton is only involved in energy production within the cell.

• The cytoskeleton has no role in cell movement.

Describe the process of mitosis and its importance in cell division.

• Mitosis only occurs in unicellular organisms.

• Mitosis involves the fusion of two cells to form a single cell.

• Mitosis is the process of cell death instead of division.

• Mitosis is the process of cell division where a cell duplicates its chromosomes and divides into two identical daughter cells, ensuring genetic stability and growth in multicellular organisms.

Discuss the function of ribosomes in protein synthesis within a cell.

• Ribosomes function in cellular respiration within a cell.

• Ribosomes function in DNA replication within a cell.

• Ribosomes function in lipid synthesis within a cell.

• Ribosomes function in protein synthesis by translating mRNA into proteins.
