Cellular Structure and Function

Front

What are prokaryotic cells?

Back

Prokaryotic cells are simple, unicellular organisms that lack a nucleus and membrane-bound organelles. Examples include bacteria.

Front

What is a key characteristic of prokaryotic cells?

Back

Prokaryotic cells do not have a nucleus; their DNA is located in a region called the nucleoid.

Front

What surrounds the cytoplasm of all cells?

Back

The plasma membrane surrounds the cytoplasm and controls the movement of substances in and out of the cell.

Front

What is the function of the plasma membrane?

Back

The plasma membrane regulates what enters and exits the cell, maintaining homeostasis.

Front

What organelle is known as the powerhouse of the cell?

Back

The mitochondria are known as the powerhouse of the cell because they convert energy from food into ATP, which cells can use.

Front

What is the role of mitochondria in a cell?

Back

Mitochondria convert energy stored in food into a usable form (ATP) through cellular respiration.

Front

What organelle is responsible for photosynthesis in plant cells?

Back

Chloroplasts are responsible for photosynthesis, converting light energy into chemical energy (glucose).

Front

What is the function of chloroplasts?

Back

Chloroplasts capture sunlight and use it to produce glucose from carbon dioxide and water.

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 organelles.

Front

What is the function of ribosomes?

Back

Ribosomes are responsible for protein synthesis in the cell.
