L2 Biology Topic 2

Which cell organelle contains genetic material (DNA) that controls the activities of the cell?

• Mitochondria

• Nucleus

• Ribosomes

• Golgi body

What is the function of mitochondria?

• It is a jelly-like substance where the functions for cell expansion, growth, metabolism, and replication are carried out.

• They make protein which is needed for various cell functions.

• They modify, package and transport proteins and lipids to destinations within/outside the cell

• They are the "powerhouses" of the cell, converting sugar into energy by cellular respiration.
