Materials Movement Quiz

What is the term for the movement of water molecules from an area of high concentration to an area of low concentration?

• Osmosis

• Exocytosis

• Diffusion

• Passive transport

Answer explanation

Osmosis is the movement of water molecules from an area of high concentration to an area of low concentration. It is the correct term for this process.

What is the process called where molecules move from an area of higher concentration to an area of lower concentration without the use of cellular energy?

• Osmosis

• Active transport

• Passive transport

• Endocytosis

Answer explanation

Passive transport is the process where molecules move from an area of higher concentration to an area of lower concentration without using cellular energy.

What is the term for the condition when the concentration of solutes is greater outside the cell than inside it?

• Hypotonic

• Isotonic

• Osmosis

• Hypertonic

Answer explanation

Hypertonic refers to the condition when the concentration of solutes is greater outside the cell than inside it. This causes water to move out of the cell, leading to cell shrinkage.

What is the process by which a cell expels waste and other materials from within itself to the outside?

• Endocytosis

• Pinocytosis

• Phagocytosis

• Exocytosis

Answer explanation

Exocytosis is the process by which a cell expels waste and other materials from within itself to the outside.

What is the term for the process where small molecules enter the cell without using energy?

• Active transport

• Exocytosis

• Diffusion

• Osmosis

Answer explanation

Diffusion is the process where small molecules enter the cell without using energy. It occurs due to the random movement of particles from an area of high concentration to an area of low concentration.

What is the term for the condition when the cell has less of a material inside the membrane than outside?

• Hypertonic

• Isotonic

• Osmosis

• Hypotonic

Answer explanation

Hypertonic refers to the condition when the cell has less material inside the membrane than outside. It is the correct choice because it accurately describes this condition.

What is the term for the process where cells expel waste or secrete substances by vesicle fusion with the plasma membrane?

• Endocytosis

• Phagocytosis

• Exocytosis

• Pinocytosis

Answer explanation

Exocytosis is the process where cells expel waste or secrete substances by vesicle fusion with the plasma membrane.

What is the term for the condition when the concentration of solutes is greater outside the cell than inside it?

• Osmosis

• Hypertonic

• Isotonic

• Hypotonic

Answer explanation

Hypertonic refers to the condition when the concentration of solutes is greater outside the cell than inside it. This causes water to move out of the cell, leading to cell shrinkage.

What is the term for the process where the cell engulfs a particle by extending its cell membrane around it and forming a vesicle?

• Exocytosis

• Pinocytosis

• Endocytosis

• Phagocytosis

Answer explanation

Phagocytosis is the process where a cell engulfs a particle by forming a vesicle through the extension of its cell membrane. It is the correct term for this process.

What is Pioncytosis?

• The process of cell division in bacteria

• A method of treating cancer using radiation therapy

• A type of plant found in tropical regions

• Process by which cells engulf and internalize particles or cells by wrapping them in a segment of their plasma membrane

Answer explanation

Pioncytosis is the process by which cells engulf and internalize particles or cells by wrapping them in a segment of their plasma membrane.
