Question

What do you know about complex tissue? Classify and explain its different types in plants with suitable diagrams.​

Answer 1

Complex Tissue​

• The complex tissues consist of more than one type of cells having a common origin. ​

• All these cells coordinate to perform a common function. ​

• Xylem and phloem are both conducting tissues and also known as vascular tissues; together both of them constitute vascular bundles.​

Types of Complex Tissue​

Xylem​

• Xylem is a vascular and mechanical tissue.​

• Xylem is a conducting tissue, composed of cells (called elements) of four different types: Tracheids, vessels, xylem parenchyma and xylem fibres.​

​

Phloem​

• Phloem is complex permanent tissue that conducts organic solutes or food materials from leaves to roots.​

• Phloem is composed of four components or cells- sieve tubes, companion cells, phloem parenchyma, phloem fibres.​
