Unit 2 - Cells

Front

What are the main differences between eukaryotic and prokaryotic cells?

Back

Eukaryotic cells have a nucleus and membrane-bound organelles, while prokaryotic cells do not. Eukaryotes are generally larger and more complex than prokaryotes.

What is the function of the nucleus in a cell?

Back

The nucleus protects the cell's DNA and regulates gene expression.

Front

What organelle is responsible for producing ATP?

Back

Mitochondria are responsible for producing energy in the form of ATP through cellular respiration.

Front

What is the role of the cell membrane?

Back

The cell membrane serves as the boundary of the cell, controlling the movement of substances in and out of the cell.

Front

What is a control group in an experiment?

Back

The control group is the part of the experiment that is used as a comparison to the experimental group, helping to isolate the effects of the variable being tested.

Front

What are ribosomes and what is their function?

Back

Ribosomes are cellular structures that synthesize proteins by translating messenger RNA.

Front

What is the function of lysosomes?

Back

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

Front

What is the role of the endoplasmic reticulum (ER) in a cell?

Back

The endoplasmic reticulum is involved in the synthesis of proteins (rough ER) and lipids (smooth ER), as well as the transport of materials within the cell.

Front

What is the significance of the cell wall in plant cells?

Back

The cell wall provides structural support and protection to plant cells, and helps maintain cell shape.

Front

What is the function of chloroplasts?

Back

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