Plant Structure and Function: Vascular Tissues

The video tutorial explains the structure and function of vascular tissue in plants, focusing on phloem and xylem. It describes how vascular tissue extends from roots to leaves, with a detailed look at tree stem layers, including bark, phloem, and cambium. The role of xylem in transporting water and nutrients is highlighted, along with its responsibility for forming annual growth rings, which help estimate a tree's age.

What are the two types of vascular tissue found in plants?

• Bark and Cambium

• Xylem and Bark

• Xylem and Phloem

• Phloem and Cambium

What is the primary function of phloem in plants?

• To transport water from roots to leaves

• To create new xylem and phloem

• To protect the stem

• To move food throughout the plant

Where is cambium located in a tree stem?

• Between the bark and phloem

• Between the xylem and phloem

• Inside the xylem

• Outside the bark

Which tissue is responsible for the formation of annual growth rings in trees?

• Phloem

• Cambium

• Xylem

• Bark

How can you estimate the age of a tree?

• By measuring the height of the tree

• By counting the number of leaves

• By counting the annual growth rings

• By examining the thickness of the bark
