Front

What is the main function of chloroplasts in plant cells?

Back

Chloroplasts convert light energy into chemical energy through the process of photosynthesis.

Front

What type of cells are considered prokaryotic?

Back

Prokaryotic cells are simple, single-celled organisms that lack a nucleus, such as bacteria.

Front

What are the three main principles of cell theory?

Back

Front

Which structure is found in all cells?

Back

Cell membrane is found in all cells.

Front

What is a cell wall and which organisms have it?

Back

A cell wall is a rigid outer layer that provides support and protection; it is found in plant cells and bacterial cells.

Front

Do all organisms have more than one cell?

Back

No, some organisms, like bacteria, are unicellular and consist of only one cell.

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis in the cell.

Front

What distinguishes eukaryotic cells from prokaryotic cells?

Back

Eukaryotic cells have a nucleus and membrane-bound organelles, while prokaryotic cells do not.

Front

What is the function of mitochondria?

Back

Mitochondria are known as the powerhouse of the cell, converting chemical energy from food into ATP.

Front

What is cytoplasm?

Back

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