The correct answer is A) Dense cytoplasm, thin cell wall, large nuclei and absence of vacuoles.
Meristematic cells are undifferentiated plant cells that are actively undergoing cell division. Characteristics of these cells include dense cytoplasm, thin primary cell walls (as they are rapidly growing and dividing), relatively large and prominent nuclei (controlling the cell cycle), and usually small or absent vacuoles, which would otherwise occupy significant volume and potentially hinder rapid division.
Mature plant cells typically have thick cell walls and a large central vacuole that can occupy up to 90% of the cell volume. Meristematic cells are found in regions of active growth, such as root tips, shoot tips, and vascular cambium.
