What is the function of the nucleus in a cell?

Back

The nucleus controls the activities of the cell and contains the cell's genetic material (DNA).

What organelle is responsible for producing proteins?

Back

Ribosomes are responsible for producing proteins in the cell.

What is the role of mitochondria in a cell?

Back

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

Front

What is a cell wall and which cells have it?

Back

A cell wall is a rigid outer layer that provides support and protection. It is found in plant cells, fungi, and some bacteria, but not in animal cells.

Front

What is the function of chloroplasts?

Back

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

Front

What is the significance of the microscope in biology?

Back

The microscope allowed scientists to observe cells for the first time, leading to the development of cell theory.

Front

What is the function of lysosomes?

Back

Lysosomes contain enzymes that break down waste materials and cellular debris.

Front

What is cytoplasm?

Back

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

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells do not have a nucleus or membrane-bound organelles, while eukaryotic cells do.
