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.

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