What is the basic structural and functional unit of all living organisms?

• organ

• cell

• molecule

• tissue

Which organelle is known as the powerhouse of the cell?

• Ribosomes

• Mitochondria

• Endoplasmic reticulum

• Golgi apparatus

What is the process by which cells engulf large particles, bacteria, or even other cells?

• Mitosis

• Phagocytosis

• Exocytosis

• Endocytosis

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

• Stores genetic information

• Regulates cell division

• Produces energy for the cell

• Processes, sorts, and packages proteins and lipids

What is the role of the endoplasmic reticulum in protein synthesis?

• Breaks down proteins into amino acids

• Provides a site for protein production, folding, and modification.

• Transports proteins out of the cell

• Stores lipids instead of proteins

What is the difference between prokaryotic and eukaryotic cells?

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

• Eukaryotic cells are unicellular, while prokaryotic cells are multicellular.

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

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

What is the function of lysosomes in a cell?

• Lysosomes act as the cell's waste disposal system.

• Lysosomes help in photosynthesis in a cell.

• Lysosomes store genetic information in a cell.

• Lysosomes regulate cell division in a cell.

What is the importance of the cell membrane?

• The cell membrane is not involved in cell communication

• The cell membrane does not control what enters and exits the cell

• The cell membrane is important for controlling what enters and exits the cell, maintaining cell shape, and facilitating cell communication.

• The cell membrane is only important for maintaining cell shape

What are the main stages of the cell cycle?

• Interphase, Mitotic Phase

• G1 Phase, S Phase

• Prophase, Anaphase

• Telophase, Cytokinesis

How do cells maintain homeostasis?

• Cells maintain homeostasis by changing color

• Cells maintain homeostasis through photosynthesis

• Cells maintain homeostasis by hibernating

• Cells maintain homeostasis through processes like osmoregulation, temperature regulation, and pH balance.
