Botany - Anatomy of Flowering Plants Question with Solution | TestHub

The cells residing at the root and shoot tips are known as meristem cells. These are undifferentiated cells and are responsible for the plant growth due to its ability to divide. These cells are small and have thin cellulosic cell walls with large nuclei, small or absent vacuoles, and absence of intercellular spaces. These cells also help to increase the length of the plant as well as the girth (lateral growth) of the stem, branches and roots.
