What structures are found in all cells?

Back

All cells contain ribosomes, DNA, a cell membrane, and cytoplasm.

Front

What is the function of ribosomes?

Back

Ribosomes are responsible for protein synthesis in the cell.

Front

What is the role of the cell membrane?

Back

The cell membrane controls which substances move in and out of the cell, maintaining homeostasis.

Front

What happens during metaphase in mitosis?

Back

During metaphase, chromosomes line up in the middle of the cell, preparing for separation.

Front

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.

Front

What is the function of the nucleus?

Back

The nucleus houses the cell's DNA and controls the cell's activities.

Front

What is cytoplasm?

Back

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

Front

What is the significance of the cell wall?

Back

The cell wall provides structure and protection to plant cells, fungi, and some bacteria.

Front

What is the process of photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen.
