Solution

Meristematic cells have a prominent nucleus and dense cytoplasm, but they lack vacuoles.
The reasons for the statement are:
Meristematic cells are undifferentiated cells capable of continued cell division.
The division helps create new cells for the differentiation of tissues and the formation of new organs.
Due to continued division, these cells have prominent nuclei and dense cytoplasm.
They lack vacuoles as they don't store food materials.
