Cell Biology Basics

What is the main function of a cell?

• Carry out essential processes for the survival of an organism

• Regulate body temperature

• Provide structural support

• Produce energy through photosynthesis

Name the organelle known as the 'powerhouse' of the cell.

• Endoplasmic reticulum

• Golgi apparatus

• Nucleus

• Mitochondria

Which organelle is responsible for protein synthesis?

• Ribosome

• Endoplasmic reticulum

• Mitochondria

• Golgi apparatus

What is the function of the cell membrane?

• The cell membrane functions as a storage unit for excess nutrients.

• The function of the cell membrane is to regulate the passage of substances in and out of the cell.

• The cell membrane is responsible for producing energy for the cell.

• The cell membrane acts as a protective barrier against external stimuli.

What is the role of the nucleus in a cell?

• Energy production in the cell

• Cell wall formation

• Control center of the cell and contains genetic material (DNA)

• Waste removal

Explain the importance of mitochondria in a cell.

• Mitochondria are responsible for cell division

• Mitochondria play a crucial role in providing energy for various cellular activities.

• Mitochondria store genetic information

• Mitochondria regulate cell communication

How do ribosomes contribute to cell function?

• Ribosomes produce energy for the cell

• Ribosomes synthesize proteins by translating mRNA

• Ribosomes regulate cell division

• Ribosomes store genetic information

Describe the function of the endoplasmic reticulum in a cell.

• The endoplasmic reticulum functions in waste removal

• The endoplasmic reticulum functions in cell division

• The endoplasmic reticulum functions in energy production

• The endoplasmic reticulum functions in protein and lipid synthesis and transport.

What is the purpose of lysosomes in a cell?

• To generate energy for the cell

• To store genetic information

• To regulate cell division

• To break down waste materials and cellular debris

How do vacuoles help maintain cell structure and function?

• Vacuoles help in cell division

• Vacuoles are responsible for cell movement

• Vacuoles store water, nutrients, and waste products, provide turgor pressure, and help regulate the cell's internal environment.

• Vacuoles produce energy for the cell
