Cell Structures

What is the difference between plant and animal cells regarding cell walls?

• Plant cells have a rigid cell wall for structure and support, while animal cells do not have a cell wall.

• Both plant and animal cells have rigid cell walls.

• Animal cells have a flexible cell wall, while plant cells do not have any cell wall.

• Plant cells have a cell membrane, while animal cells have a rigid cell wall.

What is the nucleus?

• The nucleus is the control center of the cell that houses the cell's DNA and regulates gene expression.

• The nucleus is a type of organelle that produces energy for the cell.

• The nucleus is a structure that helps in the digestion of food within the cell.

• The nucleus is a protective layer that surrounds the cell membrane.

What is the function of the cell wall?

• The cell wall provides structural support and protection to plant cells, maintaining their shape.

• To facilitate cell division

• To provide structural support and protection to plant cells, maintaining their shape.

• To regulate the movement of substances in and out of the cell.

What is the function of peroxisomes?

• Peroxisomes contain enzymes that detoxify harmful substances and break down fatty acids.

• They contain enzymes that detoxify harmful substances and break down fatty acids.

• They are responsible for protein synthesis.

• They transport materials within the cell.

What is the role of the Golgi apparatus?

• The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

• It modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

• It generates ATP through cellular respiration.

• It serves as the site of protein synthesis.

What is the function of the plasma membrane?

• The plasma membrane is selectively permeable, allowing certain substances to pass while blocking others.

• It is selectively permeable, allowing certain substances to pass while blocking others.

• It stores genetic information.

• It generates energy for the cell.

What is the function of the cell membrane?

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

• It controls what enters and exits the cell, providing protection and support.

• It stores genetic information.

• It synthesizes proteins.

What is the role of chloroplasts?

• Chloroplasts are organelles found in plant cells that conduct photosynthesis, converting light energy into chemical energy.

• Chloroplasts are organelles that conduct photosynthesis, converting light energy into chemical energy.

• Chloroplasts store nutrients and water for the plant.

• Chloroplasts are involved in the synthesis of proteins in plant cells.

What is cytoplasm?

• Cytoplasm is the jelly-like substance within the cell membrane that contains organelles and is the site of many metabolic processes.

• A rigid structure that provides support to the cell.

• The outer layer of the cell that controls what enters and exits.

• A type of organelle responsible for energy production.

What is the role of mitochondria in a cell?

• Mitochondria are known as the powerhouse of the cell; they produce energy (ATP) through cellular respiration.

• They are responsible for protein synthesis.

• They store genetic information.

• They regulate cell division.
