AI Generated Solution

The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Complex Tissues**: Complex tissues are defined as tissues that are composed of more than one type of cell. This distinguishes them from simple tissues, which consist of only one type of cell. 2. **Identifying the Options**: - **Colenchyma**: This is a type of simple permanent tissue made up of living cells of a single type. Therefore, it does not qualify as a complex tissue. - **Apical Meristem**: This is a type of meristematic tissue that is responsible for the growth of the plant at the tips of roots and shoots. It is not a complex tissue since it is involved in the formation of simple and permanent tissues before they mature. - **Ideoblast**: These are specialized cells that can be isolated and have unique properties, but they do not form a tissue type that is classified as complex. - **Conducting Tissues (Xylem and Phloem)**: These are the primary examples of complex tissues. Xylem is responsible for the transport of water and minerals from the roots to the rest of the plant, while phloem transports food produced in the leaves to other parts of the plant. 3. **Conclusion**: Among the options provided, the only correct answer that qualifies as complex tissues is the conducting tissues, which include xylem and phloem. **Final Answer**: Complex tissues include conducting tissues (xylem and phloem). ---

________ constitute the complex tissues in plants

How are simple tissues different from complex tissues in plants?

A tissue is a group of similar cells held together by a cementing substance produced by them, for performing a specific function. There are two types of tissue in plants i.e., meristematic tissue and permanent tissue. Meristematic tissue are found in all growing parts of plants such as root and shoot tips. These are called apical meristem. The tissue occurs right from the birth of plant, are called primary meristems. Permanent tissue arise from meristematic tissue and constitute major portion of the plant body. These includes simple and complex tissues. Simple tissues are parenchyma, sclerenchyma and collenchyma, complex tissue are xylem and phloem. Four students observed parenchyma tissue and drew following diagrams. Which one is correct?
