Cell Biology Review

Flashcards based on key concepts from cell biology including transport mechanisms, cell reproduction, and organelle functions.

What is an example of diffusion?

Substances scattering evenly throughout an available space.

What type of transport requires energy to move substances against their concentration gradient?

Active transport.

Which of the following is an example of an active transport process?

All of the above (Ion pump, Phagocytosis, Pinocytosis).

Hypotonic solution.

What does the process of cellular respiration provide?

Energy required for cellular work.

What are the three main parts of a cell?

Plasma membrane, cytoplasm, and nucleus.

What are organelles?

Numerous small structures that function like organs in a cell.

What is the function of ribosomes?

To manufacture enzymes and other proteins.

What term describes the series of three nucleotide bases that act as a code for a specific amino acid?

Codon.

During which phase do chromosomes align at the center of the cell?

Metaphase.

What is the significance of the Golgi apparatus?

It is the chemical processing and packaging center of the cell.

What is the genetic information stored in the cell's nucleus called?

DNA.

What is the term for the division of the nucleus during cell reproduction?

Mitosis.

What is the role of mitochondria in the cell?

They are known as the power plants, providing energy.
