Detailed explanation-1: -When weeds grow in farmland they can damage the crops and decrease the crop yeild of the farm. To get rid of the weeds without killing the crop many farmers spray their fields with herbicides. Herbicides are also made up of strong chemicals.

Detailed explanation-2: -Material like sucrose is transferred into phloem tissue using energy from ATP. This increases the osmotic pressure of the tissue causing water to move into it. This pressure moves the material in the phloem to tissues which have less pressure. This allows the phloem to move material according to the plant’s needs.

Detailed explanation-3: -Translocation is the movement of materials from leaves to other tissues throughout the plant. Plants produce carbohydrates (sugars) in their leaves by photosynthesis, but nonphotosynthetic parts of the plant also require carbohydrates and other organic and nonorganic materials.
