Question

Define the transportation system in plants and animals​

Answer 1

transportation in plant

transport of water

1. ions in soil actively transport to roots, creating an ionic difference between soil and root.
2. Water from soil enters the root into root xylem, creating a water column.
3. Water from aerial surface of plant evaporates and creates a suction that pulls water from root xylem.

transport of food and other substances

• Food (sugar) stored in leaves is loaded into Sieve tubes of phloem m tissue with help of adjacent companion cell using ATP.
• Omotic pressure in the tissue increases.
• Water moves in to the tissue.
• food from the phloem moves into the tissue having less pressure.
