Vascular Tissue Functions in Plant Transport

The video explains the transport systems in plants, focusing on xylem and phloem. Xylem transports water and minerals from roots to leaves, while phloem distributes manufactured food like sucrose and amino acids throughout the plant. The structure and function of these vascular tissues are detailed, including the role of tracheids, vessels, sieve tubes, and companion cells. The arrangement of vascular tissues in roots, stems, and leaves is also discussed.

What is the primary function of the vascular tissue in plants?

• To provide structural support

• To produce energy

• To transport substances throughout the plant

• To store nutrients

Which part of the xylem is responsible for the continuous flow of water from roots to leaves?

• Parenchyma

• Vessels

• Tracheids

• Fiber cells

What is the role of lignin in xylem cells?

• To conduct water

• To store food

• To strengthen the cells

• To transport minerals

What is the process of transporting manufactured food in plants called?

• Transpiration

• To store nutrients

Which type of cell in the phloem is dead?

• Sieve tubes

• Fiber cells

• Parenchyma

In which part of the plant do xylem and phloem form an x-like shape?

• Flower

• Root

• Stem

Where are the vascular bundles located in the stem?

• At the bottom

• At the top

• Near the edge

• In the center

What is the position of xylem in the vascular bundle of a leaf?
