The correct Answer is:
To determine the number of shoot apical meristematic zones in a twig of a plant with 9 branches and 39 leaves, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Concept of Shoot Apical Meristematic Zones**: - The shoot apical meristem is responsible for the growth of new shoots and branches in a plant. Each branch typically has its own shoot apical meristem. 2. **Identify the Number of Branches**: - According to the question, the plant has 9 branches. 3. **Relate Branches to Apical Meristematic Zones**: - Each branch will have one shoot apical meristematic zone. Therefore, the number of shoot apical meristematic zones is directly related to the number of branches. 4. **Calculate the Number of Shoot Apical Meristematic Zones**: - Since there are 9 branches, we can conclude that there are 9 shoot apical meristematic zones. 5. **Conclusion**: - The number of shoot apical meristematic zones in the twig is 9. ### Final Answer: The number of shoot apical meristematic zones expected in a twig of a plant possessing 9 branches is **9**. ---

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. __________ transports product of photosynthesis from the leaves where they are synthesised, to other parts of the plant.
