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 secondary growth mechanism?Involves the vascular cambium producing secondary xylem (wood) and secondary phloem (bark)
2. What is the structural component?Lignified cells (tracheids, vessel elements) provide high tensile strength and rigidity
3. What makes woody plants stronger than other plants?Woody plants grow extra layers of tissue called wood and bark. These layers are made of lignin, a strong chemical that keeps the stems rigid and able to stand tall and resist wind and snow.
4. How do trees grow taller over time?Each year a special layer called the vascular cambium adds new cells inside and outside the stem. The inside cells become wood, giving the tree more strength, while the outside cells become bark, protecting it.

Vascular Cambium: A lateral meristem responsible for secondary growth in woody plants.
Lignin: A complex polymer that strengthens plant cell walls, providing rigidity to wood.
Perennial: A plant that lives for more than two years, often exhibiting continuous growth.
