Chap 3 Anatomy Flashcard

Front

What is a benign tumor?

Back

A benign tumor is a non-invasive growth that is contained in one region and can be easily removed.

Front

What stage of mitosis is characterized by the separation of sister chromatids?

Back

Anaphase is the stage of mitosis where sister chromatids are pulled apart to opposite sides of the cell.

Front

What is osmosis?

Back

Osmosis is the movement of water through a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What happens to a cell in a hypotonic solution?

Back

In a hypotonic solution, the concentration of dissolved substances is lower outside the cell, causing water to enter the cell, which may lead to bursting.

Front

What occurs during the S stage of interphase?

Back

During the S stage of interphase, the DNA is replicated, preparing the cell for division.

Front

Define malignant tumor.

Back

A malignant tumor is a cancerous growth that invades surrounding tissues and can spread to other parts of the body.

Front

What is the role of the cell membrane?

Back

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

Front

What is the difference between hypertonic and hypotonic solutions?

Back

A hypertonic solution has a higher concentration of solutes than the cell, causing water to leave the cell, while a hypotonic solution has a lower concentration, causing water to enter the cell.

Front

What is diffusion?

Back

Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration.

Front

What is the function of mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells.
