Answer:
Xylem tissue helps in the transport of water and minerals. Phloem tissue helps in the transport of food. ... Transport in the xylem requires physical forces such as transpiration pull. Transport of food in phloem requires energy in the form of ATP.
Explanation:
good morning
have a wonderful day ahead
BTW how are you??
XYLEM
• Xylem tissue helps in the transport of water and minerals.
• The transportation of water is from upwards roots to aerial parts of plants.
• Transport in the xylem requires physical forces such as transpiration pull.
• Metabolic inhibitors do not influence xylem transport.
• Xylem tissues include tracheids, vessels, fibres and parenchyma and serve in the ascent of sap/water and minerals.
PHLOEM
• Phloem tissue helps in the transport of food.
• Food is transported in both upward and downward directions
• Transport of food in phloem requires energy in the form of ATP.
• Metabolic inhibitors inhibit phloem transport.
• Phloem tissues are composed of four elements: sieve tube elements, companion cell, phloem fibres, and phloem parenchyma and serve in the translocation of organic nutrients.
