What organelles contain their own genetic material?
Mitochondria and plastids
What happens if the organisation of a cell is destroyed due to physical or chemical influence?
The cell will not be able to function properly and may die.
Why are lysosomes known as 'suicide bags'?
Lysosomes are known as 'suicide bags' because if damaged, they may burst and their enzymes can digest the cell itself.
What is the function of plastids in plant cells?
Plastids are important for photosynthesis and storage of materials.
How do plastids compare to mitochondria in terms of structure?
Plastids are similar to mitochondria in external structure, as they both have their own DNA and ribosomes.
