Front

What is active transport?

Back

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy (ATP).

Front

Do prokaryotic cells have a nucleus?

Back

No, prokaryotic cells do not have a nucleus; their genetic material is not enclosed within a membrane.

Front

What are the two main reactants of cellular respiration?

Back

The two main reactants of cellular respiration are glucose (C6H12O6) and oxygen (6O2).

Front

What is the primary function of the rough endoplasmic reticulum (rough ER)?

Back

The rough endoplasmic reticulum is involved in the synthesis and processing of proteins, as it is studded with ribosomes.

Front

What is natural selection?

Back

Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring, often summarized as 'survival of the fittest.'

Front

What do both prokaryotic and eukaryotic cells have in common?

Back

Both prokaryotic and eukaryotic cells contain DNA as their genetic material.

Front

What is the role of mitochondria in a cell?

Back

Mitochondria are known as the powerhouse of the cell, as they generate ATP through cellular respiration.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen to produce energy, while anaerobic respiration occurs without oxygen.

Front

What is a vesicle?

Back

A vesicle is a small membrane-bound sac that transports substances within a cell.

Front

What is the function of the nucleus in eukaryotic cells?

Back

The nucleus houses the cell's genetic material (DNA) and controls cellular activities.
