What is meristem? Discuss its role in plants

Meristem is a specialized tissue in plants that consists of actively dividing cells, serving as the primary growth center and responsible for the development of various plant organs and tissues. It is a region of undifferentiated cells with the ability to undergo continuous cell division and differentiation, playing a crucial role in plant growth, development, and adaptation. Meristematic cells are characterized by their small size, dense cytoplasm, prominent nuclei, and lack of specialized features.

There are two main types of meristems in plants: apical meristem and lateral meristem.

1. Apical Meristem:
   - Location: Found at the tips of roots, shoots, and in the buds of the plant.
   - Function: Responsible for primary growth, leading to the increase in height or length of the plant. The ____ _____ _________ _________ _____ _____ _____.
