Unit 4 AP Biology Insta-Review (Cell Communication & Cell Cycle)

Front

What is Direct Signaling in cell communication?

Back

Direct Signaling is a type of cell communication where cells communicate through direct contact, such as a Helper T cell binding to an antigen-presenting cell.

Front

What happens during Prophase of mitosis?

Back

During Prophase, chromosomes condense and become visible, and the mitotic spindle begins to form.

Front

Can a cell undergo mitosis without cytokinesis?

Back

Yes, a cell can undergo mitosis without cytokinesis, resulting in a cell with multiple nuclei.

Front

In which phase of interphase does DNA replication occur?

Back

DNA replication occurs during the S phase of interphase.

Front

What is the role of the Rough Endoplasmic Reticulum (Rough ER)?

Back

The Rough ER is responsible for the synthesis of proteins and is involved in the secretion of endocrine signals.

Front

What is Local Signaling?

Back

Local Signaling refers to communication between cells that are close to each other, often through the release of signaling molecules.

Front

What is Long Distance Signaling?

Back

Long Distance Signaling involves communication between cells that are far apart, often through hormones traveling through the bloodstream.

Front

What occurs during Anaphase of mitosis?

Back

During Anaphase, sister chromatids are pulled apart to opposite poles of the cell.

Front

What is the function of the Golgi Bodies?

Back

The Golgi Bodies modify, sort, and package proteins and lipids for secretion or delivery to other organelles.

Front

What is the significance of the S phase in the cell cycle?

Back

The S phase is crucial for DNA replication, ensuring that each daughter cell receives an identical set of chromosomes.
