Exploring Cell Transport Mechanisms

The video tutorial from MooMooMath covers cell transport, explaining how cells move objects in and out. It distinguishes between passive transport, which doesn't require energy, and active transport, which does. Passive transport includes diffusion and osmosis, where substances move from high to low concentration. Active transport involves energy to move substances against the concentration gradient, using methods like pumps, endocytosis, and exocytosis. The video provides examples and analogies to clarify these concepts.

What does cell transport enable for cells?

• Cell division

• DNA replication

• Production of energy

• Movement of objects in and out of the cell

Which type of cell transport does not require energy?

• Exocytosis

• Passive transport

• Active transport

• Endocytosis

What is diffusion?

• Movement from high to low concentration

• Engulfing of objects by the cell

• Expelling objects out of the cell

• Movement of water from low to high concentration

What is osmosis specifically the diffusion of?

• DNA

• Proteins

• Water

• Glucose

Which process involves the cell using energy to move objects from low to high concentration?

• Active transport using pumps or channels

• Diffusion

• Osmosis

• Passive transport

What is endocytosis?

• The cell engulfs objects to bring them in

• The cell expels objects

• Movement of water

• Movement from high to low concentration

What is the opposite of endocytosis?

• Exocytosis

• Active transport

• Osmosis

• Diffusion
