Answer
(a) Phloem tissue. It is a complex permanent tissue.
(b)
| Simple permanent tissue | Complex permanent tissue |
|---|---|
| Made up of only one type of similar cells | Made up of more than one type of cells |
| Performs a single function like support or storage | Performs multiple functions, mainly transport |
| All cells are similar in structure and function | Cells are different in structure and function |
| Found in every part of plant | Found in vascular region of plant |
| Examples: Parenchyma, Collenchyma, Sclerenchyma | Examples: Xylem, Phloem |
(c) The role of phloem is transportation of food from the leaves to all parts of the plant.
