15 Questions
What is the main function of the nucleus in both eukaryotic and prokaryotic cells?
Controlling cell activities and storing genetic information
Which organelle is known as the 'powerhouse of the cell'?
Mitochondria
What is the function of the cell membrane in both eukaryotic and prokaryotic cells?
Regulate nutrient intake and waste removal
Why is the cell membrane described as semi-permeable?
Only specific substances can pass through quickly
Which molecule requires a specific transporter protein to pass through the cell membrane?
$Glucose$
What is the main difference between eukaryotic and prokaryotic cells?
Eukaryotic cells have mitochondria and chloroplasts, while prokaryotic cells do not.
What is the primary function of endocytosis?
To transport materials from the outside of the cell to the inside.
What is the main difference between active transport and passive transport?
Both a and b are correct.
What is the main function of facilitated diffusion?
To transport molecules across the cell membrane using a specific transporter protein.
What is the relationship between osmosis and the tonicity of a solution?
Osmosis occurs from a hypertonic solution to a hypotonic solution.
What is the main difference between simple diffusion and facilitated diffusion?
Facilitated diffusion uses transporter proteins, while simple diffusion does not.
Which of the following substances is NOT typically transported by active transport?
Oxygen
How does the rate of diffusion depend on temperature?
Diffusion rate increases as temperature increases.
What is the main function of the transporter proteins in facilitated diffusion?
To bind to the solute molecules and carry them across the cell membrane.
What is the main difference between exocytosis and endocytosis?
Exocytosis brings materials from outside the cell into the cell, while endocytosis brings materials from inside the cell to the outside.
Explore the differences and similarities between eukaryotic and prokaryotic cells, focusing on membrane-bound organelles and their functions. Learn about the key organelles found in both types of cells and their roles in cell metabolism and growth.
