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 tissue type?Lateral meristem responsible for secondary growth in vascular plants
2. What is the secondary xylem production?Generates wood, comprising tracheary elements, parenchyma, and fibers, for transport and support
3. What is the vascular cambium and why does it matter for trees?The vascular cambium is a special layer of cells inside the trunk that keeps adding new cells each year. It makes the tree grow thicker and stronger, so it can stand tall and keep its leaves and branches.
4. How does the vascular cambium help a tree grow wider?Each year the cambium divides new cells on the inside and outside. The inside cells become wood that makes the trunk thicker, while the outside cells become bark that protects the tree.

Lateral Meristem: A type of plant tissue responsible for increasing the diameter of stems and roots.
Secondary Xylem: Wood tissue produced by the vascular cambium, essential for structural support and water transport.
Secondary Phloem: Inner bark tissue produced by the vascular cambium, responsible for sugar translocation.
Dendrochronology: The scientific method of dating tree rings to the exact year they were formed.
