What is the role of lysosomes in a cell?

Back

Lysosomes are small sacks with digestive enzymes that break down waste, worn-out cell parts, and captured invaders.

Front

Which organelles are known to contain their own DNA and ribosomes?

Back

Mitochondria and chloroplasts are the two organelles that contain their own DNA and ribosomes, suggesting they may have lived independently in the past.

Front

What is the function of chloroplasts?

Back

Chloroplasts are responsible for photosynthesis, converting sunlight into energy stored in glucose.

Front

What is the difference between mitochondria and chloroplasts?

Back

Mitochondria are involved in energy production through cellular respiration, while chloroplasts are involved in energy capture through photosynthesis.

Front

What is the significance of the double membrane in mitochondria?

Back

The double membrane in mitochondria allows for compartmentalization, which is essential for efficient energy production.

Front

What are ribosomes and their function?

Back

Ribosomes are small structures that synthesize proteins, which are essential for various cellular functions.
