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 scientific classification?Part of the vascular system (xylem and phloem) found in Tracheophytes
2. What is the primary transport functions?Xylem: Water and mineral ascent; Phloem: Sugar (photosynthate) translocation
3. What is vascular tissue in plants?Vascular tissue is the plant's plumbing system that carries water, food, and gives support. It has two parts: xylem and phloem.
4. How does xylem move water up the plant?Xylem moves water upward using the cohesion‑tension theory. When water evaporates from leaves, it pulls water from the roots through tiny cells called tracheids and vessel elements.

Tracheophytes: A plant division that possesses specialized vascular tissues for the transport of water and nutrients.
Cohesion-Tension Theory: Explains how water is pulled up through xylem due to water molecule attraction and leaf evaporation.
Pressure-Flow Hypothesis: Describes the mechanism of phloem transport, driven by osmotic pressure differences.
Translocation: The movement of sugars and other organic molecules throughout a plant's vascular system.
