Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the xylem sap composition?Primarily water and dissolved minerals, transported upwards via the cohesion-tension mechanism
2. What is the phloem sap composition?Rich in sugars (sucrose), amino acids, and hormones, translocated bidirectionally via pressure-flow
3. What is plant sap and why is it important?Sap is the liquid that moves inside plants, carrying water, minerals, and food. It helps plants grow and stay healthy.
4. How does sap move up the tree?In xylem, water is pulled up by tension from the leaves, like a river. The water sticks together and slides along the xylem walls.

Cohesion-Tension Theory: Explains the upward movement of water in xylem due to water's cohesive properties and transpiration pull.
Translocation: The movement of sugars and other organic molecules through the phloem of a plant.
Sieve Tube Elements: Specialized cells forming the conducting channels of the phloem, responsible for sap transport.
Laticifers: Specialized plant cells or tissues that produce and store latex.
