What is the function of the cell membrane?

• The function of the cell membrane is to produce energy for the cell

• The function of the cell membrane is to store nutrients for the cell

• The function of the cell membrane is to regulate the temperature of the cell

• The function of the cell membrane is to control what comes in and out of the cell, and maintain the structural integrity of the cell

Which organelle is responsible for protein synthesis?

• The ribosome

• The Golgi apparatus

• The mitochondria

• The cell membrane

What is the main function of the mitochondria?

• The main function of the mitochondria is to produce oxygen for the cell.

• The main function of the mitochondria is to produce energy for the cell through the process of cellular respiration.

• The main function of the mitochondria is to store genetic material for the cell.

• The main function of the mitochondria is to regulate the cell's metabolism.

What is the function of carbohydrates in living organisms?

• Carbohydrates provide energy to living organisms and are important for a properly function of the brain and the nervous system.

• Carbohydrates are important for muscular function

• Carbohydrates are responsible for the formation of blood cells

• Carbohydrates help regulate body temperature

What is the difference between prokaryotic and eukaryotic cells?

• Prokaryotic cells do not have a nucleus or other membrane-bound organelles, while eukaryotic cells have a nucleus and other membrane-bound organelles.

• Prokaryotic cells are only found in plants, while eukaryotic cells are only found in animals

• Prokaryotic cells have a nucleus and other membrane-bound organelles, while eukaryotic cells do not

• Prokaryotic cells are larger in size compared to eukaryotic cells

What is the function of the Golgi apparatus?

• The Golgi apparatus stores genetic information

• The Golgi apparatus produces energy for the cell

• The Golgi apparatus is responsible for modifying, sorting, and packaging proteins and lipids for transport to their final destination.

• The Golgi apparatus helps in cell movement

What is the role of the endoplasmic reticulum in a cell?

• The endoplasmic reticulum is responsible for producing energy for the cell

• The endoplasmic reticulum is involved in protein and lipid synthesis, as well as the transport of these materials within the cell

• The endoplasmic reticulum helps in cell movement

• The endoplasmic reticulum stores genetic information

What is the main function of lysosomes in a cell?

• Lysosomes are responsible for producing energy for the cell

• Lysosomes help in cell movement

• Lysosomes are involved in the breakdown of waste materials and cellular debris

• Lysosomes store genetic information
