Question

Write the Function of following terms :

Xylem

Phloem

Pulmonary artwey .

Answer 1

Answer:

Xylem :

The basic function of xylem is to transport water from roots to stems and leaves, but it also transports nutrients.

Phloem:

Phloem is the vascular tissue responsible for the transport of sugars from source tissues (ex. photosynthetic leaf cells) to sink tissues (ex. non-photosynthetic root cells or developing flowers). Other molecules such as proteins and mRNAs are also transported throughout the plant via phloem.

Pulmonary artery :

The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs. The blood here passes through capillaries adjacent to alveoli and becomes oxygenated as part of the process of respiration. In contrast to the pulmonary arteries, the bronchial arteries supply nutrition to the lungs themselves.
