Biology Final REVIEW

Front

What is the main difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack membrane-bound organelles, while eukaryotic cells contain membrane-bound organelles.

Front

What is the function of xylem and phloem in plants?

Back

Xylem moves water up from the roots, while phloem moves food (sugars) throughout the plant.

Front

How do enzymes function in biological reactions?

Back

Enzymes are specific to a substrate, meaning their shape determines which reactions they catalyze.

Front

What is the primary function of carbohydrates in living organisms?

Back

Carbohydrates provide fast energy for cells.

Front

What process allows a virus's DNA to remain dormant in a host cell?

Back

The lysogenic cycle allows a virus's DNA to integrate into the host's DNA and remain inactive.

Front

What are the building blocks of proteins?

Back

Amino acids are the building blocks of proteins.

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis.

Front

What is the difference between the lytic and lysogenic cycles of viruses?

Back

The lytic cycle results in the destruction of the host cell, while the lysogenic cycle allows the virus to remain dormant.

Front

What is the function of the cell membrane?

Back

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

Front

What is photosynthesis?

Back

Photosynthesis is the process by which plants convert light energy into chemical energy (glucose) using carbon dioxide and water.
