What is the function of ribosomes in a cell?

Back

Ribosomes are the organelles where amino acids link together to form proteins.

Front

What is the role of the Golgi body in a cell?

Back

The Golgi body packages and distributes proteins, and proteins may be modified here.

Front

Describe the structure of the phospholipid bilayer.

Back

The phospholipid bilayer consists of hydrophobic tails and hydrophilic heads, allowing it to form a barrier in cell membranes.

Front

What happens to a cell placed in a hypertonic solution?

Back

The cell shrinks in size due to the loss of water.

Front

Identify the structure that contains the cell's genetic material.

Back

Nucleus.

Front

What is the primary function of lysosomes?

Back

Lysosomes contain enzymes that break down waste materials and cellular debris.

Front

Explain the difference between isotonic, hypertonic, and hypotonic solutions.

Back

Isotonic solutions have equal concentrations of solutes inside and outside the cell; hypertonic solutions have a higher concentration of solutes outside the cell, causing it to shrink; hypotonic solutions have a lower concentration of solutes outside the cell, causing it to swell.

Front

What is the function of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, providing protection and support.

Front

What are the main components of the cell theory?

Back

1. All living organisms are composed of cells. 2. The cell is the basic unit of life. 3. All cells arise from pre-existing cells.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.
