Back

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

Front

What is the Golgi apparatus?

Back

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

Front

Is the cytoskeleton considered an organelle?

Back

No, the cytoskeleton is a network of fibers that provides structural support and shape to the cell, but it is not classified as an organelle.

Front

What is the cell wall?

Back

The cell wall is a rigid outer layer found in plant cells, fungi, and some bacteria that provides protection and structural support.

The endoplasmic reticulum (ER) is an organelle that synthesizes proteins (rough ER) and lipids (smooth ER) and transports them within the cell.

Front

What is the function of lysosomes?

Back

Lysosomes are organelles that contain digestive enzymes to break down waste materials and cellular debris.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and various organelles.
