Explanation:
Detailed explanation-1: -Meristematic tissues are growth tissues and are found in the growing regions of the plant. The cells of a meristematic tissue are similar in structure and have thin cellulose cell walls. Each meristematic cell contains dense or abundant cytoplasm and a single large nucleus.
Detailed explanation-2: -Since meristems are young cells and are actively dividing, they do not participate actively in food preparation. Also, they do not produce a large amount of waste. Hence, they lack vacuoles.
Detailed explanation-3: -Meristematic cells are small ( 5 µm) and densely packed with cytoplasm.
Detailed explanation-4: -Final answer:-Cells having dense cytoplasm and large nucleus are called meristematic tissues.
