Question

"We are very familiar with two things found in large woody plants, wood and bark. The wood is essentially made of ________ and the bark is essentially made of ________."

Answer 1

Xylem;phloem and cork

Step-by-step explanation:

Wood is mainly known as secondary xylem found in trees

• Xylem is basically the vascular tissue which is responsible for the conduction of water and nutrients from the roots to shoots and leaves
• Secondary xylem is formed from secondary growth and is associated with lateral growth and grows from the vascular cambium
• Its cell walls are thickened by deposition of lignin which provides mechanical support to plants and consists of tracheids and vessels that are shorter and wider
• In large woody plants secondary xylem get differentiated into heartwood and sapwood

Bark is essentially made of phloem and cork

• Bark sole purpose is to provide protection to trees
• The inner bark is produced by vascular cambium which consists of secondary phloem whose innermost layer transports food from the leaves to rest of the plant
• The outer bark is a dead tissue which is the product of cork cambium
