Tubers and rhizomes are part of the root system. true or false.

False

Explanation:

Parts of the plant growing below the ground are considered as  root system. While part of plants growing above the ground are known as the shoot system. Though both tuber and rhizomes are found below the ground , they are not the part of root system. Tuber and rhizome are part of shoot system.They both are stem that grows below the ground and have buds and food reserves which make them edible. Some example of edible stems are - potato, ginger etc,

Thus the statement "Tubers and rhizomes are part of the root system" is false.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.

because the light is a great source of energy for the plants to survive. (i hope this )
