plant prepare food in their green leaves this food has to be transported to different part of the plant for energy and carrying our various activities plant absorb water and mineral from the soil with the help of their roots the water and mineral need to transported to different part of plant especially leaves which need water for the process of photosynthesis

• plant absorb water and mineral with the help of their root have plenty of hair that increase the surface area of the root here absorb water present between the soil particles water and mineral move from the roots upward throat tube like vessel mad of special type of shell forming a tissue called xylem these are vascular tissue that transport water and mineral in plant
• the food prepared in the leaves of plant is transported to different part of plants through another vascular tissue called phelom
