Question

Compound tissue is defined as-
(a) Similar type of cells held together by connective tissue
(b) Different type of cells which are different in structure and function
(c) Different type of cells performing one function
(d) Similar cells in the different region performing many functions

Answer 1

Hint: Compound tissue is a form of plant tissue consisting of several cell types. The two compound tissue styles are xylem and phloem. Conduction is the principal feature of the compound tissues. In addition, the cells of the compound tissue have thick cell walls made up of deposits of lignin.

Complete answer:
The complex tissue consists of more than one type of cells that function as a unit together. In the transport of organic matter, water, and minerals up and down the plants, complex tissues support. It is also known as conducting and vascular tissue for this purpose. The forms of complex permanent tissue that are typical are:
- Xylem or timber
- Either Phloem or Bast.
Xylem and phloem form vascular bundles together.

Additional information:
Xylem functions as the chief conductor of vascular plant tissue.
It is responsible for water and mineral ions/salt conduction. Xylem tissue along the main axes of stems and roots is arranged in a tube-like fashion. It consists of a mixture of fibers, vessels, tracheids, and ray cells, parenchyma cells. Tracheid vessels are long tubes made up of individual cells, while vessel members are open at each end.
Phloem is a plant tissue of similar significance as it is also part of a plant's 'plumbing system.' Phloem primarily carries dissolved food compounds in the plant. This conduction mechanism is made up of member and companion cells of the sieve-tube, which are without secondary walls. Both xylem and phloem produce the parent cells of the vascular cambium. Fibers, parenchyma, and ray cells are usually also included in this.
So, the correct answer is ‘(c) Different types of cells performing one function’.<.b>

Note: In vascular plants, Xylem transfers, and stores water and water-soluble nutrients. The transport of sugars, proteins, and other organic molecules in plants is the responsibility of Phloem. Owing to the rigidity of the xylem cells that sustain the plant, vascular plants are able to grow taller than other plants.
