Cell Structure and Function Concepts

Front

What are chromosomes?

Back

Chromosomes are tightly wound bundles of DNA that condense from long strands during cell division.

Front

What phase of the cell cycle do chromosomes become visible?

Back

Chromosomes become visible during prophase.

Front

What is a benign tumor?

Back

A benign tumor is a non-cancerous growth that does not invade nearby tissues or spread to other parts of the body.

Front

What is the difference between active and passive transport?

Back

Active transport requires energy (ATP) to move substances against their concentration gradient, while passive transport does not require energy and moves substances along their concentration gradient.

Front

What is interphase?

Back

Interphase is the phase in the cell cycle where the cell prepares for division, including DNA replication and growth.

Front

True or False: A tightly wound bundle of DNA is a chromosome.

Back

True

Front

What is the role of ATP in cellular processes?

Back

ATP (adenosine triphosphate) provides energy for various cellular processes, including active transport.

Front

What are the main stages of the cell cycle?

Back

The main stages of the cell cycle are interphase, mitosis, and cytokinesis.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis in the cell.

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 membrane-bound organelles.
