Front

What is the function of the Cell/Plasma Membrane?

Back

The Cell/Plasma Membrane surrounds the cell and regulates the movement of substances in and out of the cell, allowing only certain molecules to pass.

Front

What is Xylem?

Back

Xylem is the vascular tissue in plants responsible for transporting water and minerals from the roots to the rest of the plant.

Front

What is Commensalism?

Back

Commensalism is a type of symbiotic relationship where one organism benefits while the other is neither helped nor harmed, such as the pearlfish living in the sea cucumber.

Front

What is the correct equation for cellular respiration?

Back

O₂ + sugar → CO₂ + H₂O + ATP.

Front

What is the role of Ribosomes in a cell?

Back

Ribosomes are the cellular structures responsible for protein synthesis, translating messenger RNA into polypeptide chains.

Front

What is the function of the Nucleus in a cell?

Back

The Nucleus is the organelle that contains the cell's genetic material (DNA) and controls cellular activities.

Front

What is Phloem?

Back

Phloem is the vascular tissue in plants that transports sugars and other metabolic products downward from the leaves.

Front

What is the process of Mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells, essential for growth and repair.

Front

What is the difference between Mutualism and Commensalism?

Back

Mutualism is a symbiotic relationship where both organisms benefit, while in Commensalism, one organism benefits and the other is unaffected.

Front

What is the role of ATP in cellular processes?

Back

ATP (Adenosine Triphosphate) is the primary energy carrier in cells, providing energy for various biochemical reactions.
