Topic: Meristematic Tissues Types and Locations
Multiple Choice Questions
Q1. Meristematic tissues are found in plants at:
- Only the root tip
- Only the shoot tip
- Growing regions of the plant body
- Only the leaves
Q2. Cells of meristematic tissue are characterised by:
- Thick cell walls and large vacuoles
- Thin cell walls, dense cytoplasm, and large nuclei
- Dead cells with lignified walls
- Irregular shapes and small nuclei
Q3. The apical meristem is responsible for:
- Increase in the girth of the stem
- An increase in the length of the plant
- Formation of cork
- Healing of wounds
Q4. The lateral meristem is located:
- At the tips of roots and shoots
- Along the sides of stems and roots
- At the base of the leaves
- In the flower buds
Q5. Intercalary meristem is found in:
- The tips of the roots
- The base of internodes and leaf sheaths
- The bark of trees
- The xylem vessels
Short Answer Questions
Q6. List the three main types of meristematic tissues and state where each is located in the plant body.
Q7. Why do meristematic cells have thin cell walls, dense cytoplasm, and large nuclei? How do these features help in their function?
Q8. Differentiate between apical meristem and lateral meristem in terms of location and function.
Q9. What is the function of intercalary meristem? Give TWO examples of plants where this meristem is particularly active.
Long Answer Questions
Q10. Describe the structure and function of meristematic tissue. Explain why meristematic cells are considered "immature" or "unspecialised." How do these cells contribute to the growth of the plant?
Q11. Draw a well-labelled diagram of a typical plant showing the locations of apical meristem, lateral meristem, and intercalary meristem. Explain the role of each in plant growth.
APPLICATION / ANALYSIS
Q12. A gardener notices that his rose plant has stopped growing taller but has become thicker and woody over the years.
(a) Which type of meristem was active when the plant was young and growing taller?
(b) Which meristem is responsible for the thickening of the stem now? Explain how this happens.
(c) If the gardener wants to make the plant grow taller again, what pruning technique should he use, and why?
Q13. Bamboo is one of the fastest-growing plants in the world. It can grow up to 91 cm in a single day!
(a) Which type of meristem is responsible for this rapid growth in bamboo? Explain.
(b) Why do you think bamboo can grow so much faster than a banyan tree?
(c) If a scientist wanted to slow down bamboo growth to prevent it from invading nearby crops, which meristem would she target, and how?
