What is the role of lysosomes?

Back

Lysosomes are organelles filled with enzymes that break down waste materials and cellular debris.

Front

What is the nucleus?

Back

The nucleus is the organelle that contains the cell's genetic material (DNA) and controls cellular activities.

Mitochondria are known as the powerhouse of the cell, generating energy through cellular respiration.

Front

What is the role of chloroplasts?

Back

Chloroplasts are organelles found in plant cells that conduct photosynthesis, converting sunlight into energy.

Front

What is the function of the Golgi apparatus?

Back

The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

Front

What is cytoplasm?

Back

Cytoplasm is the jelly-like substance within the cell membrane that contains organelles and is the site of many cellular processes.
