2101.113.1 Comparing Prokaryotic and Eukaryotic Cells Lecture Slides

What is the fundamental unit of structure and function in living things according to Cell Theory?

The cell is the fundamental unit of structure and function in living things.

What are the two types of cells that organisms consist of?

Prokaryotic and eukaryotic cells.

What is a characteristic of prokaryotic cells?

Prokaryotic cells lack a nucleus and many other intracellular structures.

From where do all cells originate?

All cells come from pre-existing cells by division.

What do cells contain that is passed from cell to cell during division?

Cells contain hereditary information (DNA).

What is the size comparison between eukaryotic and prokaryotic cells?

Eukaryotic cells are generally much larger than prokaryotic cells.

What do ribosomes do in cells?

Ribosomes synthesize proteins in cells.

What structure encloses the cytoplasm in a prokaryotic cell?

The plasma membrane encloses the cytoplasm in a prokaryotic cell.

What is a key feature of eukaryotic cells concerning DNA?

Most of the DNA in a eukaryotic cell is housed in the nucleus.

What components are found in all cells?

Plasma membrane, cytosol, chromosomes, and ribosomes are found in all cells.

What region in prokaryotic cells contains the DNA?

The nucleoid is the region where the cell’s DNA is located.

What is the typical diameter range of bacteria?

Typical bacteria are 1–5 μm in diameter.
