Question

how do plants transport nutrients and water throughout its body? in 2 marks answer

Answer 1

plants contain vascular tissues. first is Xylem which transports water and minerals up from the roots to the leaves. and second is phloem,which transports sugar molecules ,amino acids and harmones both up and down through the plants

Answer 2

Plants transport nutrients and water throughout their body by:

• The plants absorb water and nutrients through the xylem.
• The plant absorbs water through the root hairs by osmosis and after that water is transported by xylem elements.
• The cells of the xylem make ion channels in roots, stems and leaves. these ion channels are interconnected.
• Due to transpiration, there is a continuous loss of water through the leaf surfaces. only a small quantity is kept by plants to carry out photosynthesis.
• Loss of water through transpiration builds suction pressure which pulls water through cohesion adhesion from the xylem to the other parts of the plants.
