Understanding Cell Functions

The video tutorial explains the essential functions of cells, including energy conversion, material exchange, and reproduction. Cells convert food into energy for growth and repair, exchange materials through the cell membrane, and reproduce by dividing into new cells with similar characteristics.

What is one of the primary functions of cells related to energy?

• Creating proteins

• Storing waste

• Converting food into energy

• Producing oxygen

Which organelles are involved in the energy conversion process within cells?

• Lysosomes

• Ribosomes

• Mitochondria

• Nucleus

What role does the cell membrane play in material exchange?

• It divides the cell

• It regulates the exchange of materials

• It produces proteins

• It stores energy

How do cells typically reproduce?

• Through photosynthesis

• By absorbing nutrients

• Through cell division

• By creating energy

What happens to the characteristics of a cell after it divides?

• They become inactive

• They remain the same

• They change completely

• They are lost
