FAQs on Plant Meristematic Tissues - Tissues - Class 9 - Science Video Lecture - CBSE Class 9 Biology(TISSUES)-Videos & documents by Letstute
| 1. What are meristematic tissues in plants? |  |
Ans. Meristematic tissues in plants are the undifferentiated, actively dividing cells responsible for the growth of the plant. These tissues are found in areas of the plant where growth occurs, such as the tips of roots and stems, and the buds. They give rise to specialized cells and tissues through the process of cell division.
| 2. How do meristematic tissues contribute to plant growth? | |
Ans. Meristematic tissues contribute to plant growth by continuously dividing and producing new cells. The cells produced by meristematic tissues differentiate into various specialized cell types, such as conducting tissues, epidermal cells, and xylem and phloem cells. This process of cell division and differentiation allows the plant to increase in size and develop new structures.
| 3. What are the types of meristematic tissues found in plants? | |
Ans. There are three main types of meristematic tissues found in plants: apical meristem, lateral meristem, and intercalary meristem. Apical meristem is present at the tips of roots and shoots, responsible for primary growth. Lateral meristem, also known as cambium, is found in the vascular region of stems and roots and contributes to secondary growth. Intercalary meristem is found in between mature tissues and helps in the elongation of organs.
| 4. How does the location of meristematic tissues vary in different plant parts? | |
Ans. The location of meristematic tissues varies in different plant parts. In roots, meristematic tissues are present at the tip of the root, known as the root apical meristem. In stems, meristematic tissues are found at the tip of the stem, known as the shoot apical meristem. In addition, meristematic tissues can also be found in the cambial region of stems and roots, which allows for secondary growth.
| 5. What is the importance of meristematic tissues in plant propagation? | |
Ans. Meristematic tissues play a crucial role in plant propagation. These tissues are responsible for the formation of new roots and shoots during vegetative propagation methods such as cutting, grafting, and layering. By utilizing the meristematic tissues, new plants can be produced from a parent plant, ensuring genetic similarity and faster growth compared to seed propagation.
