Questions and Answers

State the tissues and organs of the human cardiovascular system.

Tissues: heart muscle, blood vessels, blood. Organs: heart, blood vessels (arteries, veins, capillaries).

What is the equation for photosynthesis?

6CO2 + 6H2O -> C6H12O6 + 6O2

Define anaerobic and aerobic respiration.

Anaerobic respiration occurs without oxygen and produces lactic acid or ethanol. Aerobic respiration requires oxygen and produces ATP.

Label a cross-section of a leaf and state the function of the xylem and phloem.

<p>Xylem transports water and minerals from roots to leaves. Phloem transports organic compounds (sugars) from leaves to other parts of the plant.</p> Signup and view all the answers

Describe the sequence of blood flow through the circulatory system, starting from the heart and ending at the heart.
