{'meristematic tissues': [0, 0, 0, 1], 'tissues': [6, 0, 3, 7], 'plants': [11, 0, 4, 4], 'dead tissues': [0, 0, 0, 1], 'cells': [0, 0, 0, 1], 'tree': [3, 0, 1, 1], 'wood': [2, 1, 4, 10], 'growth': [1, 1, 1, 0]}

The correct statement about meristematic tissues in plants is option 4: Growth occurs in plants due to the division of cells of these tissues.

Meristematic tissues are a type of plant tissue that is responsible for the growth and development of plants. They are found in areas called meristems, which are regions of actively dividing cells. These tissues are alive and highly active, constantly undergoing cell division to produce new cells.

Option 1 is incorrect because meristematic tissues are not dead tissues and do not form wood. Wood is formed from a different type of plant tissue called xylem.

Option 2 is incorrect because meristematic tissues do not provide flexibility to plants due to their thickened walls. Instead, they are responsible for the production of new cells, which contribute to plant growth.

Option 3 is incorrect because meristematic tissues are not limited to the bark of a tree. They are found in various regions of the plant, including the root tips, shoot tips, and cambium.

In summary, meristematic tissues play a crucial role in plant growth by continuously dividing to produce new cells.
