What is a prokaryotic cell?

Back

A prokaryotic cell is a type of cell that does not have a nucleus or membrane-bound organelles.

Front

What is the main difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have both.

Front

What occurs during prophase of mitosis?

Back

During prophase, chromosomes become visible, and the spindle apparatus begins to form outside the nucleus.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of a cell, leading to water moving out of the cell.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of a cell, causing water to move into the cell.

Front

What happens to a plant cell in a hypotonic solution?

Back

The plant cell swells due to water entering the cell, which can lead to turgor pressure.

Front

What is enzyme-substrate specificity?

Back

Enzyme-substrate specificity is the concept that each enzyme catalyzes only one type of reaction with one specific substrate.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes act as catalysts to speed up chemical reactions without being consumed in the process.

Front

What is the significance of turgor pressure in plant cells?

Back

Turgor pressure helps maintain the structure and rigidity of plant cells, allowing them to stand upright.

Front

What is the function of the spindle apparatus during mitosis?

Back

The spindle apparatus helps separate chromosomes and pull them to opposite poles of the cell during mitosis.
